The Story of How I Earned My STEM Degree as a Minority

“It’s my job to prepare you for wherever you go after you leave my lab. When you go into a company, no one is going to tell you if your presentations and writings are sloppy. You won’t get promoted and you’ll never know why!”

In my post entitled, Who will benefit from Apple’s $350 billion investment?, I cited data stating that less than 10% of Science, Technology, Engineering and Mathematics (STEM) degree holders are African American – a staggering number as these are some of the highest paying careers today. With the first principle of my blog being “Creating Ecosystems of Success”, and one of my focuses being awareness of the STEM careers, I wanted to tell my story.

Thus far I’ve published posts discussing the ‘Biomedical’ sciences I’ve been trained in, ‘Regulatory’ science, the ‘Applied’ sciences, and the ‘Transferrable’ skills learned when earning STEM degrees. In these posts I’ve attempted to make these sciences easily understandable for students and families with backgrounds like my own (see the story of my blog). Potentially the most important story of all though is how one becomes a STEM professional.

I’m a firm believer in teaching the ‘how’. It’s important to encourage participation in the STEMs, but as a student who walked into my training not fully  understanding the opportunity in front of me, I think it’s also important to share what went into earning my STEM degree in a very open and honest way – the good, the bad and the ugly – no fairy tales and no magic. In this post, I’m thus revisiting both my learning points science-wise, and some personal challenges during the process as an African American male coming from Buffalo’s east side. The latter challenges may surprise you.

The majority of the visuals used in this piece are materials from my thesis. Click on any of them to enlarge them. Lastly in this piece I refer to my thesis project without getting into its specifics. I describe it in greater detail in my Basic Sciences and Basic Research post.

Learning how to do Science

I fell in love with “Life Science” in the seventh grade at Campus West in Buffalo, NY. I followed that love into Hutch-Tech High School where I majored in ‘Biotechnology’ (AP Biology). At Johnson C. Smith University (JCSU), I distinguished myself as a ‘A’ student in my core courses as a Biology major which led to my participation in the Ronald E. McNair Program, where I worked two summers in a Hepatic (Liver) Physiology lab.

It was my first time performing ‘Basic’ scientific research (see my Basic Sciences and Research post). I earned an undergraduate fellowship from the Environmental Protection Agency my last two years at JCSU. This precluded my participation in the ‘Minority Access to Research Careers’ (MARC) Program where I would’ve worked on a research project year-round, and would’ve gained more valuable experience.

Having participated in the McNair Program, I decided to pursue a Ph.D. in Pharmacology, thinking that working in a Pharmaceutical company like Pfizer or Merck would provide stable employment. Thus, the sole focus for my science training was finding a job. While a Ph.D. in Pharmacology would help me get there, I didn’t completely understand what the road to a Ph.D. in this particular STEM field entailed, as I didn’t yet know how to do science fulltime.

Rigorous Scientific Research

“Anwar has never done rigorous scientific research before,” my Graduate Advisor, a fellow Western New Yorker, wrote in my evaluation for my second lab rotation within the Department of Pharmacology of the University of Michigan. He gave me an ‘A’ which I was happy about, though based upon his statement, I wasn’t sure how I’d done in the lab. Did I perform adequately over those four months? Did I underperform, but still received an ‘A’ just because? Either way, he allowed me work under him for my thesis project – perhaps seeing some potential in me.

What made me want to stay in his lab? After my summers in the McNair Program, I knew something about the enzyme my Graduate Advisor’s lab worked on; “Neuronal Nitric Oxide Synthase” (see my Basic Sciences and Research post). I was also encouraged by two more senior students in another lab to stay based upon my advisor’s: talent, his productive track record and the productivity of his students.

By the way, in the coming years when prospective students would visit our department, my Graduate Advisor was always very adamant about the prospects getting the current students’ perspectives on the department. I think his reasons were that doctoral research is a significant life and time commitment as you’ll see later, and it’s in a student’s best interest not to walk into a department ‘blind’. Ideally, they should have a feel for the overall climate of their prospective department; its culture, its faculty and whether its students go on to establish their own careers.

The Basic Sciences and Research

The Basic Sciences and Basic Research are worlds all in themselves, worlds I initially didn’t know how to succeed in. Aside from some of my teachers in high school, there were no STEM professionals in my ecosystem in Buffalo. Also, once again, while my summers in the McNair Program gave me a taste of this new adventure I was embarking upon, they didn’t show what the experience would be like fulltime.

What qualities and attributes were needed to earn my Ph.D. in the STEM field I had chosen? One very important quality/value I received from my home ecosystem was that of hard work and the importance of doing quality work. I’ll credit my mother for this and her many years of making us do chores at home, which instilled a sense of personal responsibility and pride in my work. Also, the adversity-filled experience on my high school basketball team taught me how not to quit on things when they got hard – another valuable tool. Lastly, I was always naturally very malleable personality-wise, and open to being taught.

My Dad’s words about excelling in my coursework helped me to get into Graduate School and were useful until the end of my coursework. Once the fulltime research phase began however, it was a whole different ballgame, as working for my Graduate Advisor required a host of other ‘tools’.

I myself was a ‘project’ going into my Graduate Advisor’s lab – one which needed to be built from the ground up. There were plenty of challenging times for both of us as my first two to three years were spent literally just figuring things out. Fortunately, he was willing to teach me as long as I was willing to do the work and be taught. What do I mean by figuring things out? The following is a summary of what I learned as I worked on my thesis project:

Learning to ask Questions, to be Inquisitive and to Talk about Science

I added this learning point in last, but it may be the most important of all. I’ll credit the whole department for teaching me this lesson. One classmate and one professor stand out here. Verbally asking questions is essential to doing science. In my Basic Sciences and Basic Research post, I described how our experiments were questions themselves, but it’s also very important to be able to verbally ask questions of peers about their science both one on one, and in group settings in a respectful way.

During graduate school, I sat in on numerous seminars, and I was initially afraid to ask questions in front of everyone else. Part of it was a fear of sounding foolish. The other part of it was that while I’d excelled in my coursework as an undergraduate, I didn’t regularly talk about science with my classmates at my undergraduate institution. Over time I overcame my fears and got to the point where getting my questions answered superseded everything else.

Seeing and Understanding the Science through my Advisor’s Eyes

“You’re going to have to drive the project!” My biggest learning point was learning to see the science through my Graduate Advisor’s eyes, and not just in terms of obtaining my Ph.D. and finding a job. There was an ‘art’ to science, a thought process, a methodology, a culture and a lifestyle. It took about five years of training to get to the point where I could start see the science the way he saw it, and even talk about my project the way he talked about it.

I needed to understand the science in its entirety and appreciate the process, and all the challenges involved. I needed to approach my research like a professional; to design my experiments systematically and proactively – to think about the limitations of our experiments and the data we generated, to think of the next steps, and to always think about the final published paper.

Doing Science in the Lab Everyday vs. Learning about it in the Classroom

There’s a major difference between learning about science in a classroom setting, and actually doing quality science fulltime. For me that involved being proactive about my work, and being consistent in everything I did experimentally, in my writings and my presentations. Our experiments were questions, the results were the answers, and we needed the answers in a timely fashion. Everything needed to be approached with a sense of urgency, and in a way, time was our enemy. It also involved thinking about the project when outside of the lab – something my Advisor and his peers and competitors did – sometimes at the expense of other things.

I was now out on the edges of science in the ‘trenches’, trying to discover new knowledge. A major part of this involved approaching my thesis project like a job. And in many ways it was, as my peers and I received stipends. It wasn’t a high-paying job in terms of salary, but instead the payment was knowledge and wisdom which would equate to greater financial compensation later.

Graduate Research is in part a Job or an Apprenticeships line one of the Skill Trades

“This is your job now!” My Graduate Advisor and I had this conversation after my completing two years of coursework and starting my thesis project fulltime. I hadn’t made the connection yet that my research involved being in the lab 100% of the time. It required being on time in a job-like setting where I’d work on my project daily at a work bench – sometimes at night and on weekends. The data generated from my project would be published in scientific journals, as well as when my Graduate Advisor sought to renew his own research grants. Finally, it would be the basis for my completed dissertation, in addition to a record of my productivity after eventually leaving his lab.

Learning to Multitask

I had to learn to work smart, and not just hard. My Graduate Advisor instilled in me the ability to multitask and to, “have multiple things going at once,” as he always emphasized. In addition to working on my own project, I was also responsible for growing the stocks of proteins that the entire lab used, which was a huge responsibility. I was also the lab’s “Chemical Safety” officer who was responsible for all the lab’s waste disposal – chemical and radioactive. Multitasking was what he did on a grander scale all year. As a student, it seemed unfair at the time, but it’s a skill that has transcended our lab into other arenas, as with everything he taught us.

Learning to Compete and the Culture of Science

“You have to know where the line is, and then do your best to stay above it,” my Graduate Advisor told me years later after I graduated. Though I didn’t understand it at the time, he was teaching his students how to compete and survive. It’s not widely discussed, but science is about competition, especially in academia where at any given time, multiple labs around the country, and even around the world, are working to make the same scientific breakthrough. It’s an arena where ultimately, the group who makes the finding first gets the fame and notoriety, and future grant funding.

There was such a thing as being ‘scooped’. This is when another lab made the finding first, leaving its competitors to either disprove it, to add something to it, or to work on something else altogether. Because my Advisor was so talented and hungry, it never happened to us, but I saw it happen to some of my peers and their labs. Nothing was guaranteed. Just like he had to fight and claw to keep his lab running, I also had to fight and claw to push my project through to completion. I further had to fight and claw to stay in the department and finish my degree. Science and life are about competition.

“I know that I drove you guys pretty hard,” my Advisor shared with me years after I graduated, which we both smiled about. At times he was very abrasive, aggressive and very demanding of us. It was for a reason though and I realized during my training that working for brilliant and driven people is hard, but if you can stay in the process and take their coaching, you’ll be better off for it later.

Driven by Their Research

My Graduate Advisor attended the Massachusetts Institute of Technology (MIT) as an undergraduate, the University of Michigan for graduate school, and then the National Institutes of Health (NIH) for his own postdoctoral training before becoming a professor at the University of Michigan. We never talked about MIT in my ecosystem in Buffalo, and I just started understanding my Advisor’s pedigree towards the end of my training. His father was a scientist as well, and he thus had exposure to science at an early age, and even earned a couple of patents before starting college. Don’t get me wrong, having parents in the STEMs isn’t a necessity to getting into one of the fields yourself, but the early exposure can pay huge dividends later.

This is a good place to state that my Graduate Advisor, his peers, and scientists at most research universities are driven by their scientific research, and they’re always thinking about it; late at night, and even on family vacations. The argument can be made that their research is their purpose for living. The truly talented ones are further tough enough to withstand any environmental changes such as when the second Bush Administration cut the NIH’s budget, causing many labs around the country to downsize or perish altogether, while others figured out how to survive.

“You all are very different than we were! When I was a graduate student, we fought over the latest issues of the Journal of Pharmacology and Experimental Therapeutics (JPET),” said one of the more senior and celebrated faculty in our department who was jokingly said to have invented the Heart. He felt that we weren’t studying up on our field enough in our spare time beyond our core curricula. Most of us were only doing the minimum reading and studying, something my Graduate Advisor also stayed on me about during my training.

Learning to Manage my Life outside of the Lab so that I could do Science

Learning to manage my life outside of the lab so I could do science

The accompanying newspaper clipping is from one of Buffalo’s local weekly black publications, The Challenger. My mother proudly submitted the story and that’s her handwriting on the top of the clipping. It was a big deal back home and she even shared with me that I’d exceeded her expectations which was very gratifying. When looking at the clipping, it’s something to proud of, but what you don’t see there is that there were a host of personal learning points outside of the lab as well – experiences which could’ve derailed the whole thing.

Being African American and ascending in education and a career often leads to discussions of “forgetting where you came from”. So, I want to close with what I learned about how life outside of the lab can affect one’s ability to do science and be a professional. Sometimes it’s actually necessary to leave certain parts of your old life behind. I learned on numerous occasions during my STEM training that I had to protect both my project and my life. That is, I had to make strategic decisions in my personal life that would increase my chances of finishing my degree and surviving to talk about it.

While working on my thesis I got involved in a very chaotic romantic relationship which compromised my mind, spirit and overall well-being at times; nearly derailing my project and potentially adversely affecting my Graduate Advisor’s entire lab all at the same time. There was one day I consider a near death experience – something I’ve discussed with friends and relatives only in bits and pieces. Fortunately, I survived, but this type of thing wasn’t restricted to my significant other.

There were two instances involving two close friends whom I consider my second and third brothers. One incident transpired over a Thanksgiving holiday and the other a Christmas holiday – both of which involved nearly getting pulled into violent confrontations late at night at nightclubs and parties in my hometown of Buffalo, NY. One friend had too much to drink and in the process of having his own fun, inadvertently splashed another guy with his beer. The guy who got splashed was unhappy about it and started following us around the venue. While I thought bullets might fly, my friend got away with just getting punched and knocked out temporarily. Fortunately, we both made it home safely.

In the second incident, another buddy wanted to stay and confront some guys over a female outside of a nightclub. Apparently, he was looking at the guy’s lady and there was an initial confrontation I didn’t see inside the venue. My friend didn’t want to appear afraid and wanted us to take our time leaving. When I realized what was going on, I wanted to leave immediately – something he and I clashed over afterwards. Fortunately again, nothing happened, and we got out of there safely.

Neither of these incidents were worth the potential price to be paid. Neither my significant other, or either of my friends considered the possibility of my showing up to the lab in a cast, with a black eye, or with teeth missing, or maybe being laid up in a hospital, unable to continue my research. The take home message from all of this is that you must be your own best advocate in life. None of us can avoid tragedies, but there are some things we can avoid.

You must protect what you’re doing, sometimes from people around you in your family circle, friends or significant others, because someone else’s selfishness and bad decisions can hinder your life and professional aspirations. In my case it was earning my STEM degree and starting my career.

Closing Thoughts

“Give a man fish and you’ll feed him for a day. Teach a man to fish and you feed him for a lifetime.”

I included this famous quote from the Chinese Philosopher Lao Tzu because the road to my STEM degree was literally like learning how to fish. The opening quote from this piece is from one of my many talks with my Graduate Advisor. In some ways our relationship evolved into that of a father and a son which I’m very, very grateful for as not every student had this. I saw several peers leave partway through their graduate training without their doctorates either due to a loss of hope, or irreconcilable differences with their advisors. Some were African American, but not all were.

This is my STEM story and there are many others out there. I want to point out that the point of telling this story was not for my glorification. As I said in the opening, I think it’s critical to explain all sides of the process in addition to simply encouraging students to get involved in the STEMs solely because of our under-representation as African Americans, and because of the monetary benefit. The how is very, very important. If you’re a STEM professional, I encourage you to also tell your story to STEM-hopefuls in an age-appropriate way.

I’d like to end this story by acknowledging the late Dr. Minor J. Coon.  Dr. Coon was not only a member of my Thesis Committee (on the program above), but he was also a legend and a pioneer the in the study of Phase I Drug Metabolizing Enzymes – Cytochrome P450s particularly.  Dr. Coon actually trained my Graduate Advisor who subsequently suggested asking Dr. Coon to be on my committee – something that surprised me as we all looked upon him with great reverence.  Growing up on Buffalo’s east side, I never dreamt of being a part of such a well accomplished tree of scientists.

Can You Keep One Eye On The Business Ball Without Taking Work Home With You This Evening?

Two of the focuses on of my blog are Career Discussions, and Health and Wellness. When stepping up into management positions, balancing one’s health with the new demands can be a challenge. The title of this contributed post is thus entitled; Can You Keep One Eye On The Business Ball Without Taking Work Home With You This Evening?

* * *

Managers are always told that they shouldn’t take work home with them. We all need a break now and again, after all. By taking care of admin into the early hours, you’ll soon start to suffer. Keep this going for too long, and you could experience the notorious ‘manager burnout’. If that happens, your work will suffer. You may even have to take time out. Whatever happens, it won’t be good.

Instead, managers across the world work hard to switch their business phones off and leave their laptops in the office. And, the chances are this is an effort you also attempt to get behind. Good for you. Prioritizing your own time is part of what makes you such an excellent manager.

The trouble is, leaving the office at five and switching off altogether could leave you stalling in the morning. Rather than getting straight to work, you’ll have to take a little time to get back into things. Often, that’ll leave you behind before the day has even started.

Hence why we’re going to suggest something revolutionary. While you still want to leave work at the office, it is possible to keep your mind on the ball regardless. All you need to do is make use of the following outlets during your down hours.

Podcasts

Image Source

We all love a podcast, don’t we? Whether we’re listening to Serial or The Daily, this is now the way many of us choose to unwind. Lucky for you, there are plenty of business-based podcasts which can help you relax while teaching you a thing or two. Shows like Fire Nation can teach you about every aspect of entrepreneurial life. In episodes like this one where JLD chats with Joe Kashurba, you can even learn how to grow your business. Options like the Social Pros Podcast can even teach you about content marketing and everything social media. While fun and interesting, these options also fuel the embers of your business fire, rather than putting it out overnight.

YouTube videos

Who doesn’t spend at least some of their evening browsing YouTube? If you get stuck in loops of cat videos, opt instead for inspirational business-based channels. The official TED channel includes talks for individuals from every industry, including business. You may also want to subscribe to entrepreneur-specific YouTubers such as GaryVee. His business advice has gained him well over 1.5 million subscribers. Watching these guys, you’ll feel like you’re relaxing with a past time you love. But, you can bet you’ll learn a few useful tidbits.

Listen to industry news

While we can’t help with any specific suggestions, it’s also crucial you listen to industry news. By finding field-specific radio stations, you can get your fix of what’s going on in the rest of your industry. That can help with everything from finding your target audience, to keeping them interested. Rather than listening to 80s pop music on your way to and from work, then, consider sticking this on and learning something you wouldn’t otherwise.

A Look at STEM: What are the Basic Sciences and Basic Research?

“In addition to understanding the fundamental principles of one’s field, a major part of understanding Basic Research and Science is understanding the instruments and technologies used.”

One of the focuses of my blog is awareness of the Science, Technology, Engineering, and Mathematics (STEM) fields. Thus far, I’ve written posts covering the “Biomedical Sciences” I’ve been trained in including: Pharmacology, Toxicology, ADME/Drug Metabolism, and Inhalation Toxicology. I’ve also written a post discussing “Regulatory Science” in the Public and Private sectors, in which I discussed the “Applied Sciences” and “Research and Development”. In this post I want to discuss the “Basic Sciences” and “Basic Research”, the foundations from which we receive all our new scientific knowledge.

The foundations of any of our commercial scientific and technological innovations are the Basic Sciences and Basic Research. A simple Google search led me to a site which stated that the four major Basic Sciences are: Biology, Chemistry, Mathematics and Physics. Many people consider Physics to be the ‘Grandfather’ of all the sciences because each of the others rest upon its shoulders in some way. Any of the other Basic Sciences fall under one of these four branches.

For Biology for example, many of the sciences underneath its vast umbrella include: Biomedical Sciences, Agricultural Sciences, Environmental Sciences, etc. Within the Biomedical Sciences there are the sciences I’ve written about, as well as: Cellular and Molecular Biology, Genetics, Microbiology, Virology, etc. The same is true for Chemistry under which there are: Analytical Chemistry, Organic Chemistry, Physical Chemistry, etc. While Physics is its own discipline with its own subdisciplines, as you’ll see later, its principles permeate throughout the other major sciences, especially when you’re carrying out ‘Basic’ scientific research.

Basic Research is simply the pursuit of new knowledge and the understanding of a specific area of focus. As described throughout my blog, my Ph.D. is in Pharmacology, with two and a half years of training in its sister science, Toxicology. In the Basic Research world scientists known as ‘Principal Investigators’ run labs at major research institutions, like the University of Michigan, where they have specific research areas of interest.

Principal Investigators ask specific research questions in their areas of focus through their research projects. They arrive at their answers for these questions through experiments and report their results in papers published in scientific journals. To carry out their research, which I’ll describe later, Investigators usually receive grant funding from federal sources such as the National Institutes of Health (NIH), or from the Private Sector. As you’ll see there is a business side to research, both in academia and in the private sector.

* * *

As described in my Pharmacology post, there are numerous sub-disciplines within Pharmacology. My Graduate Advisor’s area of focus was ADME/Drug Metabolism which involved some aspects of Biochemistry and Cell Biology based upon the questions he was asking. For the remainder of this post I am going to discuss my thesis project in his lab to give readers a feel for what Basic Research is and why it’s important. Some of the terms I’m going to use will be on the esoteric side, but I’m going to do my best to keep the discussion as simple as possible.

The title of my thesis project was the “Labilization and Proteasomal Degradation of Neuronal Nitric Oxide Synthase” – a mouthful for anyone unfamiliar with the field. If you google me, you’ll find two ‘first author’ publications that I published in my Graduate Advisor’s lab with the assistance of my lab mates; fellow students, postdoctoral scientists, senior scientists, and technicians. I’m crediting the entire lab because, while I was the first author on these papers and it was my thesis project, my colleagues also contributed their expertise and man-hours. Everything in our lab was done as a team. I also contributed to my lab mates’ work. My two first author publications are:

Ubiquitination and degradation of neuronal NO-synthase in Vitro: Dimer stabilization protects the enzyme from proteolysis published in Molecular Pharmacology and;
Tetrahydrobiopterin protects against Guanabenz-mediated inactivation of neuronal nitric oxide synthase in Vivo and in Vitro published in Drug Metabolism and Disposition.

What does all this mean? In simple terms, our bodies are made up of numerous organs, systems and tissues. These are, in turn, made up of cells, nucleic acids and proteins which do the work on the ground level in our bodies. When we become ill, infected with a bacterium or a virus, poisoned by a toxicant, or develop cancer, there’s an underlying biochemical change that has occurred on the cellular level. It could be the enhanced production of viral particles, DNA damage leading to tumor formation, inhibition of an enzyme’s function, or the breakdown of key cell signaling pathways.

In Type II Diabetes, for example, the cells of our bodies become nonresponsive to endogenous ‘Insulin’, which naturally allows them to take up glucose from our bloodstreams. The breakdown of this intracellular signaling pathway leads to the hallmark maladies associated with Type II Diabetes. Pharmaceuticals likewise exert their therapeutic effect by modulating these same cellular processes. But how do these processes occur? And how do pharmaceutical companies design drugs we use to treat diseases? The answer is Basic Research.

My Graduate Advisor, a Pharmacologist and a Biochemist in training, was very interested in how exogenous chemicals could selectively control the fates of proteins within cells. Prior to my entering in his lab, he discovered that an anti-hypertensive drug called ‘Guanabenz’ could inhibit the metabolic activity of the protein “Neuronal Nitric Oxide Synthase” (nNOS), and then cause the loss of the protein itself in rat penile tissue. Other chemicals also inhibited the protein’s activity but didn’t cause a loss of the protein. So again, there was something unique to each chemical and their effect on the protein in the cell. There was a trigger that made the protein go away in certain instances. But how was this all happening?

In my earlier posts, I discussed how animals are used as models for studying human health based upon shared organ systems and metabolic pathways. My thesis project investigated this phenomenon in rat penile tissue using an in vitro system, meaning that it all took place in test tubes in a ‘cell-free’ system where we could mimic the cellular environment and control the conditions of our reactions. This allowed us to ask questions we couldn’t ask in cell or animal models.

My first finding was that our protein of interest had to undergo a major structural change for it to degrade. Chemicals like Guanabenz triggered this structural change by causing the breakdown of the homo-dimeric active protein form to its inactive monomeric form. Other chemicals prevented this structural change and protected the protein from degradation. What was even more fascinating was my second finding. This structural change was triggered by loss of a specific intracellular Cofactor which was important for maintaining the homo-dimeric form of the protein. It was the loss of this cofactor that triggered the subsequent toxicity in the rat penile tissue.

My project was a very ‘mechanistic’ project in that we were going down into the ‘weeds’ to figure out how the effect in the whole animal occurred. Why was this important and what could be done with this information? Several things. It could be used to create new drug targets, and it could also be used to predict and understand similar toxicities by chemicals with similar structures. These are all things Chemical and Pharmaceutical companies, and Regulatory Agencies consider when bringing new products to the market and when protecting human health.

During my thesis I performed ‘Bench Science’. I literally had a work bench and performed experiments every day, working to generate quality data I could publish. As I worked to answer my research questions, I also learned a wealth of research techniques and technologies, in addition to learning how to perform scientific research (discussed in the next post). While it was a biological project in nature, my thesis project involved the use of numerous analytical chemical tools and technologies, many of which involved some understanding of Chemistry and Physics.

In this section I’m going to introduce a few terms commonly used in the research world which were foreign to me when I started. ‘Assay’ for example, is just a fancy term for an established and widely used experimental method. The others will be explained throughout and should be easy to follow. The devices and technologies described are hyperlinked.  The methods, tools and processes I utilized during my research included the following:

Cellular and Molecular Biology techniques: We used numerous cell models to: generate large quantities of our protein of interest for our in vitro experiments, and we had other cell lines to ask questions about the fate of the protein within cells. The latter involved inserting (transfecting) the DNA of the protein of interest into cells. This involved the use of Cellular and Molecular Biological techniques, and the use of Cell Incubators and, in some instances, Orbital Shakers to culture (grow) the cells, depending on the cell line.
Stoichiometry: This key aspect of General Chemistry was a critical part of all our experiments. Specifically, it was central in the calculation of ‘Molar’ concentrations when preparing the numerous ‘Chemical Reagents’ that were used including: buffers, cellular media, solvents, matrices, resins and so on.
Column Chromatography and Protein Purification Methods: We used numerous protein purification methods, particularly Affinity and Size Exclusion chromatographic methods to create clean preparations of our proteins of interest and other preparations. This allowed us to study its activity in isolation, its protein levels and ask questions about any structural changes.
Gel Electrophoresis and Protein Detection Methods: We used electrophoretic and antibody-based detection methods for measuring actual protein levels for visual analysis and quantification. The bread and butter technique of my experiments was called the ‘Western Blot’ analysis, whereby the proteins in my in vitro assay were separated by size, then detected, and finally, quantified using a radio-labeled antibody. One of techniques used in the lab was the Protein Assay, which allowed us to quantify the amount of protein in various preparations using a 96-Well Microtiter Plate Reader; arguably the workhorse for not just our lab, but also for neighboring labs. The Microtiter Plate Reader contained a Diode Array that measured changes in absorbance which helped inform us of the concentrations of the protein preparations (Beer’s Law). One of the 96-Well plates used in the Microtiter Plate Reader is picture below without any dyes or solutions.
Enzymatic Activity Assays: We used numerous assays to measure the activity of our protein. The primary assay used for measuring the activity of the protein was the “Oxy-Hemoglobin Assay” where we measured the conversion of Oxy-Hemoglobin to Met-Hemoglobin. We used this conversion to quantify the amount of Nitric Oxide produced by our protein with and without inhibitors/inactivators. This assay relied u9pon measuring changes in absorbance and thus, once again, the Microtiter Plate Reader was the primary tool for asking questions about the activity of our protein of interest. In some instances, other methods were used to measure activity as described next.
Physical and Analytical Chemical and Detective Methods: Consistent with most ADME/Drug Metabolism labs, a tool we heavily relied upon was High Performance Liquid Chromatography (HPLC) – a classic detection tool used for measuring the following: cofactors, molecules, metabolites, and proteins; based on their chemical properties and how they behaved in specific organic and non-organic solvents. Later in my thesis project, our lab purchased several Mass Spectrometers, which is the most sensitive chemical detection tool. However, my projects didn’t require me using them.

In addition to understanding the fundamental principles of one’s field, a major part of understanding Basic Research and Science is understanding the instruments and technologies used. As the researcher, understanding these technologies is critical to understanding what your data are and are not telling you. If you’re listening to a peer’s seminar, or reviewing their publication, understanding the technologies also helps you understand their work. In some instances, a researcher’s understanding of the technologies gives them ideas about combining them to ask unique questions.

What’s the measure of how good a scientist is? It’s their publication and funding records. The top scientists and their labs continuously come up with good ideas, then publish their work in competitive scientific journals. When scientists continually come up with good ideas and continue to publish quality work, they’re more likely to continue to secure funding and ascend in their field. The reciprocal is true for scientists who don’t come up with good ideas and don’t publish.

It’s worth noting here that the rules for publishing are different in the Private Sector vs. Academia. Research projects in the Private Sector are usually geared towards innovation and selling a product. As a result, research findings are considered ‘Intellectual Property’ which companies own and may not want to disclose out of fear of losing a competitive advantage to other companies in their sector. The research projects are also very focused, and the scientists have less freedom in terms of what they can work on. Employment is also heavily dictated by that particular company’s economic health and overall direction.

A byproduct of training in the Basic Sciences and performing Basic Research is acquiring the knowledge and expertise which the Applied Sciences and the Private Sector use to bring new products to the market. The training can also be used to form Consulting groups (see my Regulatory Science post). If a scientist is thoroughly trained, he or she will also acquire a separate set of skills described in my blog post entitled; The transferrable skills from a doctoral degree in the basic sciences. In my case, the discipline was Pharmacology, but this applies to pretty much any of the other Basic Science and Basic Research disciplines.

How long can it take to earn a degree in a STEM? It depends on the STEM area. The path I chose took roughly 5-6 years. That length of time was impacted by my first learning how to do research (discussed in my next post), and then working through the complexities of my project. If the systems and tools for asking your scientific questions are already established, then it’s a clearer path. If you’re establishing your methods for the very first time though, it could take a little longer.

If you’re building upon someone else’s work, you must also hope that they’ve reported their methods and results honestly and accurately. If so, their work will be easier to reproduce. The hard part when doing Bench Science is that many experiments don’t work initially, and it can take time to get your systems to the point where you can start generating quality, publishable data. During my thesis, I easily performed hundreds to thousands of experiments. It took time to establish my systems and their conditions, and then it took more time to generate quality, publishable data to answer my scientific questions.

Having role models is critical when training in the basic sciences. Your graduate advisor typically plays this role. Why is it important to have role models? Having inspirational figures to look up to whilst studying can be extremely important. They can provide motivation, career guidance, representation, and inspiration. These can serve as examples of what can be achieved with hard work and dedication, and they can provide invaluable advice on navigating the industry’s challenges. In addition, people who have managed to earn their way into the science industry by their own merit, such as Monica Kraft Duke Settlement, can be great motivators and inspire you to create your future.

The Basic Sciences and Basic Research are vast. This post just focused on one aspect of Pharmacology – a Biomedical Science. Whether it’s a: pharmaceutical, an industrial chemical, a medical device, a GMO crop, a Blockchain Technology application, or one of Elon Musk’s new SpaceX rockets, someone had to do the underlying research which gave rise to the innovation. I’m going to close by reiterating something from my Pharmacology and Toxicology posts, which is that each Basic Science has its own professional society and annual meeting. Thank you for taking the time out to read this blog post. I hope I was able to give you an understanding of Basic Sciences and Basic Research.

Your Five-Year Plan

Two of the principles of my blog are “Creating Ecosystems of Success” and “Long-Term Thinking and Delayed Gratification”. A key to being successful is looking into the future, setting goals and planning the steps towards achieving those goals. The following contributed post is thus entitled; Your Five-Year Plan.

* * *

Do you often find yourself just going through the motions of your life, without any clear goals or targets? Just living life day to day, without purpose or focus? Many of us do. Then, a few years down the line, we look back at what we’ve achieved and find that nothing has changed. We still have debts, we still live in the same place, our relationship hasn’t developed or grown, we’re no closer to getting what we really want from our life, and our career has stalled.

Well, this happens when we don’t have a plan. You’re never going to hit your goals if you don’t have any. You get one life, you should be making the most of it. A five-year master plan can help you to do this. Five years is a great period of time. A lot can change in five years. Think about who you were five years ago, what you enjoyed doing, who your friends were. Now, look at your life today. In five years, we grow, we change, we start to enjoy different things, we meet a lot of people. You might eat differently, look after yourself more or less, and even go to bed at a different time. Five years is long enough to make massive changes and achieve a lot, but not too long that you can’t look ahead with focus and determination. So, here’s a look at how to create a five-year master plan to help you to develop and get what you want from life, as well as some ideas of things that you should include.

The Benefits of a Five-Year Plan

If you are the kind of person that just lives day to day, you might not see the point of a five-year plan. But, it can have some definite benefits. It gives you focus. Instead of a general idea of what you want to do with your life, you’ll have clear and well-defined goals for all areas. Five-years means that you’ve still got time to be spontaneous and do what you want, as long as you get back to your plan and continue working towards your aims. It also helps you to prioritize, to stay on track, to keep motivated and to say no to things that would take you off course.

Merely sitting down and writing goals forces you to think about what you want and reflect on your choices so far. You are also statistically more likely to achieve things if you’ve written them down. Something about writing down a target makes it real and gives you a greater focus to achieve it.

How to Create One

Sit down and think about your life so far. Think about what your dreams were when you were younger, and if you still want the same things now. Then, write yourself a Wishlist. Think of your ultimate goals and dreams, no matter how outlandish they might seem. Write them all down. Even those that might take longer than five years to achieve.

Then, ask yourself why you want these things? Will hitting these goals make you happy or improve your quality of life? Try to picture your life if you reach these targets? Take some time to imagine your ideal life. Now, look at your list again, do you need to add or remove anything?

Now you’ve got the what’s and the why’s. It’s time to think about the how’s. This is potentially the most crucial part of your master plan. Without plans, your goals are vague and unreachable. Ask yourself what you can do to meet your targets, or to get significantly closer to them. Write these down too. Now, let’s take a look at some of the things that you might want to include.

Money

Money is often a big part of our future plans, and your goals might depend heavily on your current financial situation and what you want from your future. If you need to borrow to help you achieve other goals, this is the website to help. If you need to save, or pay off debts, work out how much you need to save each year.

You might have something specific that you’d like to achieve financially, perhaps saving enough to start a business, or to buy a house. Or, you might want to improve your credit score and pay off your debts. Five years is long enough to make massive changes to your financial situation. Think about your goals and take the time to make a household budget to match.

Relationships

Source

Your relationships will also depend on where you are now and what you want in the future. If you are in a relationship, marriage and children might be in your near future. If not, you might want to think about meeting the right person and starting down the road to settling down.

Wherever you are romantically, there will be other relationships that you need to nurture. Make giving your friendships plenty of love and attention a goal. You might also want to rekindle old relationships, mend family feuds or meet new friends and expand your circle.

Career

Your career is a big one. Getting your career right can improve your financial situation and allow you to take more time for your relationships. Do you have any burning ambitions? Do you want to start your own business, or would you like to dive into a career change? If you are happy where you are now, you might just want to aim for a promotion or try to learn more about your industry to become more confident at work.

Health and Fitness

Source

Our health is something we often neglect when making plans for the future. Especially when we are young and healthy. But, it shouldn’t be. Your health and fitness are essential to a happy and long life. But, your goals don’t need to be huge. They might just be to carry on what you are doing or to make small improvements to your diet. Think about small, realistic changes that you can make that will improve your health and fitness.

Break it Down

Now you’ve got your five-year targets, you should think about breaking them down. A five-year master plan is fantastic, but it can be hard to stay focused when something is so far away. So, break it down and make plans for the year ahead. Thin about what you can do in the next 12 months to help you to reach your goals.

A look at STEM: What is Regulatory Science?

The first principle of my blog is “Creating Ecosystems of Success”, and one of the main focuses of my blog is awareness of the Science, Technology, Engineering, and Mathematics (STEM) careers and fields. Up to this point I’ve written several posts discussing the ‘Biomedical Sciences’ which I’ve been trained in: Pharmacology, Toxicology, ADME/Drug Metabolism, and Inhalation Toxicology. In this post I want to discuss what “Regulatory Science” and “Regulatory Affairs” are – the scientific interface between the ‘Public’ and ‘Private’ sectors where the safety of commercial products sold to the general public are determined – a science not well understood by the general public despite its importance to our everyday lives – myself included initially.

“You can always go into ‘Regulatory’,” a classmate who I’ll refer to as Greg said, during graduate school at the University of Michigan. I was feeling the stress of working on my thesis project which consisted entirely of ‘Bench’ or ‘Basic’ scientific research, and lamenting that I wasn’t sure if I wanted to stay in academia once I finished my dissertation. Greg had worked in one of the bigger Pharmaceutical companies, and understood everything that comprised them. At the time I wanted a career with a ‘regular’ schedule which is something I’ll describe more in depth in my next blog post which will discuss the ‘Basic Sciences’. I, coincidentally, did start a career as a Regulatory Scientist by accident, depending on your belief system.

When giving my annual Toxicology lecture at SUNY Albany, I always tell the class that Regulatory Scientists are ‘Watch Dogs’ or ‘Gate Keepers’ who evaluate new products generated by the ‘Private Sector’ to make sure they are safe for the public. What types of products am I talking about? You can start with anything in and around your home, whether it be food products, pharmaceuticals, or industrial chemicals, air fresheners, household cleaners, paints, or cosmetics. These are just the chemicals which we consume, or are exposed to on a personal level. Another context is the environment. For every product generated, questions must be asked about what that product will do to wildlife, their unique ecosystems, lakes, oceans, the air, etc. Here think about coal and petroleum products as good examples.

The term ‘Regulatory’ is rooted in the ‘Regulations’ put in place by Federal and State governments – laws and statutes which dictate how and when the government should act in the general public’s best interests to ensure that the products they are being sold are safe. Going back to the previous paragraph, there are regulations for example for registering the following: crops and commodities, livestock and poultry, pharmaceuticals, medical devices, industrial chemicals, industrial materials and textiles, and energy products such as petroleum and coal. We’re very close to the use of ‘Nanomaterials’, so products that contain them are of particular interest now.

Here is a good place to think back to the 2016 Presidential election where the then candidate, Donald J. Trump, discussed the need to rollback excessive, costly and burdensome regulations put in place by the Obama administration to allow private businesses to grow and thrive. Having an understanding of Regulatory Science and Regulatory Affairs is the essence of that discussion because it takes resources to demonstrate the safety of products; otherwise it can cut into profits if their uses are restricted. Important questions to thus consider are: 1) is there such a thing as over-regulation; and 2) is there a happy balance between business and keeping the public and environment safe? Some food for thought.

Regulatory Scientists work in both Public and Private sectors. On both sides each must understand the Federal and State government laws and regulations. Scientists in the Private sector must understand the regulations and provide the government with the data it needs so that their companies can efficiently register their products. Scientists in the Public sector must understand the regulations to ensure that the companies trying to register their products are in compliance, so as to not cause injury to individuals in the general public and create subsequent litigation. While this post is about Regulatory Science, it’s also worth noting here that most of the private companies also have scientists working in the ‘Applied Sciences’ and ‘Research and Development’, which is where their new products come from – examples are the Food, Pharmaceutical, Biotech, and Crop-Science companies.

Where do Regulatory Scientists receive their training and what types of skills do they need? Most Regulatory Scientists receive their training in the ‘Basic Sciences’ at major research universities, such as the University of Michigan, where I received my training. This means that they first become trained in specific scientific areas of expertise – Pharmacology and Inhalation Toxicology in my case – and they then use those knowledge sets in the Regulatory world to make safety decisions. The same is true for the Applied Sciences where that expertise is used to create new products. As you can see these worlds are closely interrelated.

The four Biomedical Sciences I’ve discussed in detail – Pharmacology, Toxicology, ADME/Drug Metabolism and Inhalation Toxicology – are all basic sciences which translate to the Applied Science and Regulatory sciences. Scientists trained in these fields and others can either remain in academia, or take their skill sets into the Public or Private sectors. See my post entitled, “The transferrable skills from a doctoral degree in the basic sciences” to get a feel for what skills are necessary to work in the Regulatory Sector or Regulatory Affairs. Just briefly, a couple are of the skills are the ability to: 1) work on teams; 2) write; 3) plan; and 4) speak orally, as there are lots and lots of meetings.

There are typically two contexts for Regulatory Science – one which takes place in a classic laboratory setting, and the other which takes place in an office setting. In the lab setting, experiments are carried out to test products safety. In the government office setting, scientists interpret the results generated on specific products using the above-mentioned regulations and policies which each scientist has to learn when starting in the field. It’s worth noting here that science is constantly changing and evolving, and thus a challenge to working in the Regulatory sector in government settings is staying current on new and relevant scientific breakthroughs and methods. This can be done in any number of ways including attending national meetings, and participating in special ‘work groups’, for example.

A third context for Regulatory Science is consulting. Many scientists, after working in the Public or Private sectors, eventually opt to the start their own consulting companies. These consulting groups typically work with Private sector companies to get their products registered swiftly and efficiently, with the goal of keeping their costs as low as possible.

What do Regulatory Scientists make in terms of salary? That is in part dictated by one’s degree level, and whether the scientist works in the Public or Private sectors. Scientists in both sectors can start out making $70,000. Federal and State Regulatory Scientists are typically paid according to the ‘General Schedule’. While Regulatory Scientists in Private Industry are paid according to what that company determines the individual is worth, and the mutually agreed upon salary.

In closing, when you think about Regulatory Science, think globally. While the United States Government has numerous agencies to protect the general public – the EPA, FDA, USDA and the NRC to name a few – other countries around the world have them as well. And there are actually global partnerships and cooperatives amongst nations which are important when it comes to international trade and commerce, in addition to environmental protection. A career in Regulatory Science thus has the potential to touch not only the lives of those in your immediate circle, but also those in faraway places.

The next posts in this series will talk about what Basic Research and Science are, and then my personal journey towards becoming a Scientist. If you enjoyed this post you may also enjoy:

Father’s Day 2018: Dad’s Doctor and his Lawyer, and a Discussion on Careers

“Your brother is going to be my Doctor, and you’re going to be my Lawyer!”

A Quick Plug

Hello. Thank you for clicking on this link and I hope you enjoy this essay. Writing a book was the genesis of me blogging and becoming a video content creator. I am close to publishing part one of my book project entitled, The Engineers: A Western New York Basketball Story. Please consider visiting the page to learn more about the project and see promotional content I’ve created surrounding the project. And now on to our feature presentation.

Father’s Day 2018

Happy Father’s Day. My 2017 Father’s Day blog post talked about some of my father’s life and money lessons, and there were many. I wrote some more about us in my second essay submitted to A Voice For Men entitled: Two very well-behaved boys left to figure things out on their own: Reflections on growing up ‘Blue Pill’, which discussed how my brother and I had to figure out several aspects of manhood on our own. There weren’t a lot of men around growing up, and there were limitations in what we were taught by the men we did know.

For this 2018 post, I’m going to go in a different direction and will discuss what Dad wanted both me and my brother to be career-wise, versus what we actually became. This piece isn’t an “ode to fathers” per se, but instead a set of thoughts and ideas based upon something my father said to us as children, which will serve as a jumping off point for things me and those in my circle regularly discuss today as adults – things that have impacted our family dynamics as the years have gone by. As described in my piece Challenging stereotypes and misconceptions in academic achievement, Dad’s fatherly guidance helped me reach my academic potential. He also stimulated me to start thinking about potential careers at an early age.

Envisioned Careers

“Your brother is going to be my Doctor, and you’re going to be my Lawyer!” Dad said on one of our summer visits in the mid-1980s. The three of us were crossing a street in downtown Schenectady, NY and he turned and gave his proclamation to the both of us – communicating with one of his hands – his signature style. Like many parents, Dad had his own plans for what we should be. Somewhere along the line, he determined that it should be a medical doctor and a lawyer, and as with everything Dad said, he said it with lots of authority, pretty much commanding us.

Not having either in my immediate family circle on either my mother’s or father’s side, I didn’t know much about what lawyers did. I had some idea of what medical doctors did because I had gone to see them on numerous occasions as a child. One of Dad’s first cousins was in fact a medical doctor, but we didn’t see him enough to be able to ask him about his career. In elementary school it hadn’t occurred to me what I wanted to be career-wise, though I got the inkling that it would be something scientific after really enjoying “Life Science” in the seventh grade – essentially beginner’s Biology. My brother had begun showing signs of being both artistic and creative.

But what made my father so enamored with medical doctors and lawyers in terms of careers for his sons? Dad was always one for stability which is why he became a junior high science teacher. Neither of his parents had gone to college, so he was a first-generation college graduate. From what I can see, some parents naturally want their children to do better than them. In the mid-1980s, the conventional wisdom was that medicine and law were two very high-profile professions which would lead to affluent and comfortable careers/lifestyles.

“I know that your grandfather would be very proud of you being a doctor and all,” Dad said on several occasions regarding my Ph.D. years later. He didn’t necessarily understand what my doctorate stood for, or the skills it represented, but the title of ‘doctor’ meant a lot to him – something I witnessed in the coming years both positively and negatively. Coincidentally, I think he initially discouraged me from pursuing a doctorate – potentially because he only knew Ph.D.s in the context of the school system, and not the ‘research’ and ‘regulatory’ worlds.

White Collar Careers

With one of the principles of my blog being “Critical Thought”, I believe it’s important to look at things in their entirety. So, while Dad wanted these two prestigious careers for us, what would it have taken for us to get into these two professions? The answer is it would’ve taken lots and lots of school for the both us and then, most likely, considerable debt to pay back. This is something very important to consider for parents and students looking to attend college to pursue ‘White-Collar’ careers.

In terms of higher education, thinking out the entire plan long-term is critical – considering the cost of the degree, how to get a quality degree for the least amount of money possible, what the expected salary will be on back end, and finally how much debt will need to be paid back. According to a 2014 article in Forbes, the average amount of debt for Law School graduates ranged from $84,000 to $122,158. Also, according to a recent 2018 article by Credit Donkey, the average medical school graduate finishes with $192,000 of debt.

Keep in mind that these are on top of however much debt was accrued during one’s undergraduate studies. The numbers probably weren’t as high thirty years ago, but it’s important to be mindful of blindly chasing certain careers based upon titles and prestige. If it’s something a student really wants to do, that’s different, but the costs still ought to be considered.

If you run the numbers and your prospects aren’t good, I would recommend not going into debt for that particular degree. A mentor recently taught me that the economy actually dictates the need for specific careers at a given time. I don’t know what the prospects were like for lawyers in the mid-1980s when Dad announced his wish for me, but as I progressed in my education, I heard more and more stories about the market being ‘saturated’ with them. I likewise heard that the landscape for medicine had changed, and in some ways, it wasn’t as lucrative a career as it once was.

In terms of my career, I figured it out as I went along. I had an interest in the biological sciences and thus followed that path. I pondered going to medical school at one point, but decided against it after a professor at Johnson C. Smith University encouraged me and some of my classmates to study up on what it entailed – the demands, the lifestyle, and the backend costs.

Blue Collar Careers and Skill Trades

It’s also important for students and parents to keep in mind what the student is good at, and where their gift/passion lies. While I turned out to be the son that was interested in the Biology, my brother’s gifts were completely different. He turned out to be a ‘design and build’ –type of guy. He had the gift for designing things, constructing things, taking them apart, and he was quite formidable with tools and devices. He started studying Architecture in college but didn’t finish, but in hindsight, he may have also been well suited for one of the ‘skill trades’ – something that didn’t come up as a child as college and ‘White-Collar’ careers were emphasized as opposed to ‘Blue-Collar’ careers.

Speaking of the trades, since finishing my own education, I’ve realized that there is power in learning one or more of the skill trades. There will always be the need to build and fix things. That includes: the electricity and plumbing in your home, airplanes we travel on, the public transportation vehicles we ride to work on every day, and so much more. If your refrigerator breaks down as mine did recently, for example, you either have to buy a new one or hire someone to come and fix it – unless you can do it yourself.

Unfortunately, our society looks down on the Blue-Collar careers in some ways, though they pay very, very well and don’t require the years of schooling doctors and lawyers need – the same is true for the debt required to train for the latter two careers. In my opinion, individuals who are proficient in the trades people are willing to pay for; and those who also have some business training, stand to make lots of money as they can do things like start their own companies and hire other people.

My brother never finished college and has become a bit of an inventor/entrepreneur which actually is the route that our technology giants like: Bill Gates, Steve Jobs, and Mark Zuckerberg took. There may have been some luck involved for each of them, but these men are reminders that in some instances, ideas and skills are more powerful than the degrees themselves. Today for example, there are quite a few individuals making significant incomes without being ‘degreed’ – those who can write code for Blockchain Technology applications for example. Also, while my brother isn’t degreed, he’s also not saddled with a significant debt payment of any kind – a tremendous advantage.

Financial Literacy Regardless of Field

As for me, depending on your belief system, I got lucky. I pursued a Ph.D. in a Science, Technology, Engineering and Mathematics (STEM) field at a time when the economy rewarded individuals with such degrees. What’s even more significant is that I finished only with a little bit of debt from my undergraduate studies. Because I pursued a STEM degree, I didn’t pay for any of my graduate studies so I didn’t have a hefty loan to pay back for those five to six years of graduate school. This brings me to my closing point. It wasn’t until I finished that phase of my science training that I realized that I was missing something very, very important – something some kids are given early, and something others stumble upon later in life if at all.

Regardless of whether or not you get a college degree, a trade or some sort of entrepreneurship, the critical piece is understanding money. Something not discussed much in our younger years was wealth-building – something that is possible for everyone, and independent of one’s career choice as it involves a specific set of behaviors that I’ve written about in my Net Worth and Debt Snowball pieces. Understanding the concepts of wealth-building: budgeting, living within one’s means, delaying gratification, investments, and ‘Compound Interest‘ – these are the keys to a great and bountiful life, not necessarily the careers and titles themselves, contrary to what many people think.

Prestige and titles are nice, but if you read Dr. Thomas Stanley’s The Millionaire Next Door, you’ll see that there are many high-income professionals who look the part, but who are actually struggling. In my blog post about the Tax Reform and Jobst Act, I referenced a 2016 article in the Washington Post entitled: The shocking number of Americans who can’t cover a $400 expense which showed that even some individuals making over six figures, surprisingly couldn’t cover such an emergency.

I never wanted to be one of those people. I may be different from most, but I’d rather secretly live nice and comfortable with a simple outward appearance, as opposed to looking wealthy and struggling behind closed doors. That’s a personal choice however – one which everyone must make for themselves.

Closing Thoughts

In closing, our parents sometimes have dreams of what they want us to be. Some kids actually go ahead and fulfill their parents’ dreams while others go their own way. In some instances, our parents can discourage us from what we really want to do based upon what they know and feel from their lives.

There is thus a complex set of decisions to be made based upon: what one really wants to do, their unique gifts, what they’re passionate about, and how they’ll be able to earn a living on the back end. In the end, the economy dictates what’s needed at that particular time – it will determine who gets hired and how much they will be paid. Lastly, no matter what path is chosen, the critical piece is understanding money. Once again, Happy Father’s Day.

Tableau hosts discussion on educating in a data driven world revisited

Shortly before the Examiner closed its operations in 2016, I was invited to write a story on a symposium hosted by the company Tableau regarding the increasing role of data and analytics in education. During my doctoral and postdoctoral research in Pharmacology and Toxicology, I experienced firsthand the importance generating quality data and statistical analyses, though I didn’t realize that data and analytics was literally its own field. It turned out that there was a whole data and analytics community/world, with companies like Tableau creating software for quality data analyses and interpretation. Likewise there are whole careers in data and analytics, and these professionals are critical components of Academia, and the Public and Private Sectors.

* * *

On June 9, 2016 Tableau hosted a symposium in Washington DC titled; “Educating in a Data Driven World”. The symposium took place at Washington DC’s St. Regis Hotel and featured a panel of experts from the United States’ leading institutions of higher education. Among them were:

• Mike Galbreth, Associate Professor of Management Science, University of South Carolina
• Danial Lopresti, Professor and Chair of Departmen3t of Computer Science and Engineering, Director of Data X Initiative, Lehigh University
• Cheryl Phillips, Hearst Professional in Residence, Stanford University
• Vijay Khatri, Associate Professor of Information systems, Arthur M. Weimer Faculty Fellow, Co-Director, Kelley Institute for Business Analytics, Indiana University
• Jana Schaich Borg, Postdoctoral Associate, Duke University
• Jon Schwabish, Adjunct Professor in the McCourt School of Public Policy and the McDonough School of Business at Georgetown University, Lecturer at the Maryland Institute of College of Art

The Moderator of the panel discussion was Ben Jones, Director of Tableau Public. The panel discussion revolved around the state of analytics education and how higher education is responding to the increased demand for analytics skills in the workplace; a topic all in itself which impacts pretty much every sector and discipline; Politics, Humanities, Business and lastly Science, Technology, Engineering, and Mathematics (STEM) fields. Specific topics discussed were: Issues pertaining to data literacy, how students can be better educated to increase their data literacy, the importance of communication and soft skills for data professionals, and the common traits of individuals interested in analytics.

“Just like there are a lot of programs to help young girls get into STEM fields, we think that it’s important that we help educate our students to be successful in an increasingly data driven world. We have academic curricula for teachers to help them get started with Tableau in the classroom. We do whatever we can to help close the skills gap,” said Tableau for Teaching Manager Emma Trifari. Tableau’s motivation for hosting the panel was the understanding that there is a huge skills gap in the data world, and in order to fill that gap, data literacy needs to start from the beginning.

The Transferrable Skills from a Doctoral Degree in the Basic Sciences

“What does having a doctorate in the basic sciences actually mean, and what does it actually empower one to do particularly in the sciences?”

When I set out to earn my Ph.D. in Pharmacology, I wasn’t clear on what I was supposed to be getting from my doctoral research besides the degree itself, and hopefully a job at the end of it all. It turned out that in addition to the expertise gained in my thesis project, there were several other important skills that the University of Michigan’s Department of Pharmacology sought to instill in me and my classmates.

These skills – some of which took time and effort to learn are actually very critical in any of the “Biomedical” sciences that I’ve recently written about: Pharmacology, Toxicology, ADME/Drug Metabolism and Inhalation Toxicology, and others. They’re further critical in any of the ‘Basic’ research sciences.  All Ph.D.s are not the same, nor are all Ph.D. programs the same and you may have learned some or all of these skills in yours. The following piece discusses the transferrable skills scientists in the Basic research sciences receive during their training which are very valuable in: Academia, and both the Public and Private sectors.

Going Home to Ann Arbor

July 8, 2015 marked the ten year anniversary of the earning of my Ph.D. (doctor of philosophy degree) in Pharmacology from the University of Michigan. It was a tremendous accomplishment educationally and scientifically for a kid from Buffalo’s eastside. Coming from my community, it had far reaching effects and implications socially that I didn’t understand at the time.

On June 2, 2015, the University of Michigan’s Department of Pharmacology hosted its annual Pharmacology and Experimental Therapeutics Career Day. The event was designed to expose the department’s current students, to the multiple career options available to them following their doctoral and masters level trainings. As a key component of the day, select alumni (myself included) were invited back and asked to discuss their careers and share their experiences.

Going back to Ann Arbor is always like going home. Six of my most of the most meaningful years were spent there learning about science and life. My graduate advisor for example taught me lasting lessons not only about pharmacological research, but also how to be a professional and how to survive in this world. In a lot of ways, he was like a second father.

While I experienced tremendous growth during graduate school earning my degree, some of the most meaningful lessons about my doctoral degree itself took place after leaving Ann Arbor. College towns like Ann Arbor are unique in that the University is a major part of the town’s culture, and as such there is an unusually high concentration of highly educated individuals there. Needless to say every place isn’t like that, and you don’t realize it until you leave.

The Power of a Degree

Once I left, I discovered that my degree touched people in many different ways. I actually wrote a ten part series for the Examiner titled “Pursing a Ph.D”. One part of the series was dedicated to the social implications of the degree, specifically some of my biological father’s words of wisdom.

“I wouldn’t tell people that you’re a doctor when you first meet them. They’re going to expect you to have certain things and look a certain way.” Upon moving to Albany, NY for my Postdoctoral fellowship, my father gave me this stern recommendation. I didn’t understand why he was encouraging me to keep my great accomplishment a secret, but to make a long story short, he was afraid of other people’s expectations, and there was some validity to his fears.

Our society associates the title of doctor with wealth, no matter what kind of doctor the person is. The late Dr. Thomas Stanley, author of the Millionaire Next Door series discussed in his books that being a high-income professional, and the accumulation of wealth don’t directly correlate. Wealth building involves: sound money management skills, financial literacy, and in some cases delayed gratification – components that not all doctors have.

Varying Perceptions and Responses

“I wasn’t aware of Dr. Dunbar’s level of education when I met him so I was unable to address him by his proper title,” said a teacher at a Career Day at a local elementary school in late May. I casually revealed to the class that I earned a Ph.D. but didn’t introduce myself as “Dr. Dunbar”. As best I could, I tried to humbly explain to her class of sixth graders that success, in this case earning a doctorate, is a door that swings both ways.

That is, some people will instinctually be happy for you, celebrate your success and look at you with reverence, while others will unfortunately feel threatened and insecure about it and behave as such. This can be relatives, friends, significant others, coworkers, etc. There are numerous stories I could tell about this both good and bad, but there isn’t enough room in this piece.

In any case let’s circle back to the University of Michigan’s Pharmacology and Experimental Therapeutics Career Day. What does having a doctorate in the basic sciences actually mean, and what does it actually empower one to do particularly in the sciences? As the lone government Regulatory Scientist at the Career Day, I interestingly drew the first time slot for the morning speakers.

The Transferrable Skills

I had no idea what my peers were going to talk about, but surprisingly most of our talks shared similar core themes. Each of us in our own way, communicated that in addition to becoming experts of our thesis projects, in my case the “Ubiquitination and Proteasomal Degradation of Neuronal Nitric Oxide Synthase”, there were a host of other skills that we had all learned that were applicable to our current careers and other areas, particularly the Public and Private sectors. Among them were:

• Critical thinking/Problem solving skills
• The ability to multi-task, organize and coordinate multiple projects at one time
• The ability to write clearly
• The ability to speak and present clearly
• The ability to work on teams
• The ability to adapt and understand new systems

My classmates had all gone on to do some very impressive things. Each of us worked on research projects in the areas of: Cardiovascular Pharmacology, Receptor Pharmacology, and Drug Metabolism, just to name a few. However after graduation, not everyone had taken the traditional path of becoming tenure-track academic researchers.

Some had gone on to: work in the pharmaceutical industry, start their own companies, become consultants, become academic professors or administrators (at small teaching colleges), or science advocates. Our varying careers spoke in part to our department’s openness to prepare its students for the potential for other careers, in addition to the versatility of the skills that we had acquired. See my Pharmacology blog post to get a feel for just how vast the field is.

Closing Thoughts

In summary, earning any doctorate whether it be in the sciences or the humanities is a tremendous accomplishment. That being said, it’s what one does with the skills they’ve acquired during their thesis research that makes them great, not the degree itself. In the sciences, in addition to mastery of one’s area of expertise there a core set of skills learned. And it is these skills that make that person exceptional no matter which field they go into.

I’m going to end this differently than the original piece by saying that with a simple Google search, the publications I proudly generated during my research days I believe are all still available online for those curious individuals.

A Look at STEM: What is Inhalation Toxicology?

“While other bodily tissues can tolerate varying degrees of O2 deprivation, it is well understood that even short periods of deprivation of the brain can cause irreversible damage, unlike with long periods of food and water deprivation.”

Inhalation Toxicology

With the exception of my Blockchain Technology post, my previous Science, Technology, Engineering and Mathematics (STEM) posts have covered the fields of: Pharmacology, Toxicology, and ADME/Drug Metabolism – all of which are considered ‘Biomedical’ sciences. Similar to those fields, Inhalation Toxicology as a discipline dates back to over a century ago, and is very complex regarding the wealth and depth of information available. It’s also still evolving today.

The goal of this post is not to address every detail and nuance of the field, but instead to give readers unfamiliar with it a basic introductory understanding of the discipline. This post was prepared for a general audience and thus any fellow Inhalation Toxicologists who may read this, may find it a little too simplistic. That’s okay though, as the goal is to educate others on our field and what we do. Further details about the many aspects of Inhalation Toxicology can be accessed online, or in scientific journals.

This overview of Inhalation Toxicology definitely falls under my principle of ‘Creating Ecosystems of Success’ as it is a very unique knowledge and skill set possessed by only a select few – one of which I acquired accidentally when seeking training in ADME/Drug Metabolism as a ‘Postdoctoral’ scientist. Why is Inhalation Toxicology a unique skill set? I’ll start with a holistic discussion about the three routes of human exposure which will take us briefly into another biomedical discipline; ‘Anatomy and Physiology’, which deals exclusively with the organ systems within the human body, and how they collectively work together at the tissue and cellular levels.

Routes of Exposure

My posts regarding Pharmacology, Toxicology, and ADME/Drug Metabolism focused on exposure to chemicals primarily through the oral route – ingestion through the mouth and then absorption into the ‘Gastrointestinal Tract’ (GI-Tract). While we typically think about the ingestion of chemicals through the oral route, the reality is that humans can be exposed to drugs and toxicants through two other routes; the dermal route by way of our skin, and the inhalation route by way of our ‘Respiratory Tracts’ – the region spanning from our nasal passage down into our lungs where gas exchange with the atmosphere occurs. Each route has its own unique properties anatomically which impact the potential absorption of chemicals into the body where they can exert their therapeutic or toxic effects at specific tissues.

Each route receives differing amounts of what’s called the ‘Cardiac Output’ or the blood delivered from the heart. On average, the GI-Tract receives 21%, the skin receives 9%, and the lungs receive 100% of the heart’s Cardiac Output. This makes sense as the function of the lungs is to facilitate gas exchange between our bodies and the Earth’s atmosphere.

The Alveoli and Gas Exchange

The lung’s ‘Alveoli’ are critical for the body’s absorption of ‘Molecular Oxygen’ (O2) into the bloodstream. Once inhaled, the O2 in the air is very rapidly absorbed into the pulmonary capillaries from the alveolar spaces where it binds to the ‘Hemoglobin’ in our blood while the ‘Carbon Dioxide’ (CO2) releases into the alveolar spaces to be exhaled. This exchange of O2 and CO2 are both very rapid and efficient in healthy lungs – something our bodies do without us even thinking about it. What allows for this very efficient exchange of gases with the environment is a very, very thin 0.5 micron three-cell layer separating the alveolar spaces from our pulmonary capillaries.  These capillaries immediately receive and return blood to the heart for distribution to the body.

Without the continuous exchange of O2 and CO2 through our lung’s alveoli, our bodies could not function as O2 is a necessary substrate for our body’s many tissues at the cellular and molecular levels. This is important because while other bodily tissues can tolerate varying degrees of O2 deprivation, it is well understood that even short periods of deprivation of the brain can cause irreversible damage, unlike with long periods of food and water deprivation. For this reason alone, maintenance of proper respiratory function is critical. With that, I’ll transition into what Inhalation Toxicology is and why it’s important.

Hazard Through Inhalation

Inhalation Toxicology is the study of the harmful effects of chemicals on living systems through the inhalation route of exposure via breathing – typically as it applies to mammalian species. It’s a very important field as respiration is a critical biological process for mammals as described above, and thus any toxicant that compromises the body’s capacity to exchange O2 and CO2 with the environment is very dangerous.

Before I discuss the types of chemical agents that can cause injury through inhalation exposure, I’ll first describe the two types of effects that can result from exposure to inhalation toxicants; ‘Portal of Entry’ effects and ‘Systemic’ effects. A Portal of Entry (POE) effect is an effect produced in the tissue or organ of first contact with a chemical or toxicant. In this case it’s an effect where a toxicant causes damage starting from the nasal passage down into the multiple regions of the lung. There are multiple regions and cell-types along the respiratory tract – each with specific functions – all of which can be uniquely injured.

In laboratory settings described later, some POEs are instant when observing lab animals and manifest as ‘clinical signs’ which are visible. Irritation in the respiratory tract can trigger the ‘Paintal’ reflexes and ‘Bradypnea’ in rodents which are immediate changes in the breathing patterns of the animals through very sensitive nerve processes and receptors in respiratory tissues. Anyone who has worked in a research lab and has opened a bottle of concentrated Hydrochloric Acid outside of a fume hood appreciates how quickly irritation can occur, as it only takes seconds to feel the burning sensation in the nose followed by: coughing, watering eyes, shortness of breath, etc.

Long-Term Effects

Other POE Effects are more time dependent and can take hours, days, or weeks to fully set in. Some are some are reversible, while others are irreversible. Prolonged exposure to some toxicants can cause ‘Inflammation’ in the lungs leading to ‘Pulmonary Fibrosis’ (formation of scar tissue) or the formation of ‘Pulmonary Edema’ – both of which compromise lung function and can eventually be fatal. ‘Asbestos’ poisoning causes injury through prolonged activation of the ‘Immune’ system in the lungs, damaging them over time as the Asbestos particles cannot be removed once inhaled.

Smoking cigarettes is a good example of people willingly injuring their lungs. The paper used to roll cigarettes and the ‘Tobacco’ inside them contain thousands upon thousands of compounds before the cigarette is even ignited. Once lit and those chemicals are ‘combusted’, they transform into numerous other chemicals – some of which are referred to as ‘Reactive Intermediates’ which themselves come into contact with the cells of the Respiratory Tract. Years and years of direct cigarette smoke inhalation can cause irreversible damage leading to diseases like Lung Cancer. There is also risk of lung injury from living in industrial areas where there is the potential to inhale combusted compounds and particulates from factory emissions.

Before moving on, I’ll add here that while many inhalation toxicologists consider the lung itself to be the most important part of the Respiratory Tract, recent science has shown that the Nasal Passage is also a toxicologically revelation tissue as it relates to inhalation exposure. It contains drug metabolizing enzymes similar to those described in my ADME/Drug Metabolism post.  The lungs do as well.  Some chemicals can thus damage these regions if inhaled for prolonged periods of time.

Systemic Effects

Systemic effects refer to injury/toxicity in other parts of the body beyond the Respiratory Tract. If a chemical/toxicant can efficiently pass through the lung’s alveoli as described earlier, it can enter the blood stream and into the body’s general circulation.  From there it can damage other organs as discussed in my Toxicology post. Medicinally, some therapeutics such as anesthetics for surgeries are actually administered this way – Halothane is an example.

Two classic systemic inhalation toxicants are Carbon Monoxide (CO) and Hydrogen Cyanide (HCN) which I’ve hyperlinked in case you’re curious to learn more about how they work.  While CO poisoning has been associated with accidental deaths from tailpipe emissions in garages, HCN is a known potential chemical weapon which is particularly dangerous in enclosed spaces such as subway stations – something our intelligence agencies are very aware of.

These are just a few examples of toxicity through the inhalation route of exposure. There are many other chemicals and substances that can cause injury and in some cases therapeutic benefit through the inhalation route of exposure. Many industries and groups highly consider Inhalation Toxicology. They include:

The Chemical Industry: Pretty much any industrial chemical that’s generated has the potential for inhalation exposure depending on its ‘Physical-Chemical’ properties, and how it’s used. These include paints, pesticides, and disinfectants – any product that companies are looking to sell to the general public.
The Tobacco Industry: The Tobacco Industry has to have a firm understanding of what cigarette smoke does to its customers and bystanders inhaling ‘second hand’ smoke. They are thus very interested in the long-term effects of cigarette smoke inhalation.
Nanoparticles and Nanomaterials: We’re very early in the use of ‘Nanomaterials’, and there is a lot that is unknown regarding the toxicity of these particles – in this instance, when they’re inhaled.
National Defense: Our military and the ‘Defense’ sector very much care about Inhalation Toxicology as soldiers are sometimes sent into theaters of war where enemies use biological and/or chemical weapons. There are also unfortunate incidences where chemical weapons are unleashed on civilians such as the recent chemical attack in Syria where rescue officials believe the agent used was Chlorine gas.
The Pharmaceutical Industry and Medical Devices: Some medicines can and must be delivered through the inhalation route. A classic example is the use of ‘Albuterol’ for patients with Asthma, but there are numerous other examples such as when anesthetics and other treatments are given through inhalation exposure.
Public Health: Federal and State governments, academic researchers and private sector companies are always cognizant of how the general public is exposed and affected by any of the chemicals described above which invariably end up in the air, and can cause any number of disease states including Asthma, and in some cases Lung Cancer.

Inhalation Toxicology Research

Having introduced the field in terms of background and context, I’ll now discuss some of its experimental and technical aspects using visuals provided by CH Technologies – a leading company in the manufacture of Inhalation Toxicology exposure systems. Inhalation Toxicologists and Scientists not only need an understanding of the biology of injury to the Respiratory Tract via inhalation exposure (examples described above), but they also need an understanding of how to properly create the experimental conditions to test for inhalation toxicity. It’s relatively straight forward to feed a test specimen the chemical of interest in food or water, or to apply it via the skin, but how do you administer it for inhalation exposure?

The answer is that the chemical must be administered as a ‘gas’, an aerosol’, a ‘dust’, or even a ‘cigarette  smoke‘ suspension in some instances. This involves some knowledge of Chemistry and Physics, as well as Mathematics and Statistics. A key aspect of any toxicological field is proving the concentration/dose tested and properly correlating it with the effects observed. Scientists must thus be able to verify their test atmospheres, and there are numerous ‘analytical’ chemical methods for doing so.

Gases, Aerosols, Dusts and Vapors

Some chemicals readily exist in the ‘Gas Phase’ – that is they have what is referred to as a high ‘Vapor Pressure’ and are very ‘Volatile’. Some are liquids while others are solids. Mothballs are an example of a volatile substance – a solid which ‘sublimes’ and converts directly into a vapor. They give off the unique odor most of us know from our grandparents’ closets, and are comprised of the chemical ‘Naphthalene’ which itself has a high vapor pressure. Other chemicals have low vapor pressures and are considered ‘Non-Volatile’ and must form aerosols to be inhaled – think of a mist from a spray bottle. ‘Dust’ suspensions can be generated as well for experiments. In some instances, generating inhalable suspensions are not feasible depending on the properties of the test material of interest.

Test Models and Species

While the test species for Inhalation Toxicology studies vary, the species of choice is typically rodents – rats and mice. In some instances guinea pigs and primates are used. Each of these species possess the same organs that humans possess for the most part, and are thus useful models for human exposure.  Scientists must be well trained in both caring for the test animals and also operating the highly specialized equipment used in these studies which I’ll cover next.

Test Systems

Testing a drug’s/chemical’s efficacy/toxicity through inhalation exposure requires the use of an ‘exposure chamber’ where an inhalable atmosphere of the test article is generated for inhalation exposure by the test subjects.  The accompanying picture shows a single level chamber with the accessory equipment used for measuring the chamber’s inner atmosphere using some of its ‘exposure ports’. Click on the image to enlarge it. Using the accessory equipment, the concentration of the test material in the chamber can be monitored by the scientists running the experiment, in addition to other important measurements including: O2, CO2, temperature and humidity to name a few.

To generate the chamber’s test atmosphere, most modern systems utilize an air-pressure pump to create an in “inflow” into the exposure chamber, and a vacuum pump to create an “outflow” from the chamber – together creating a consistent supply of O2, and removal of CO2 for the test subjects. The accompanying diagram shows a complete inhalation exposure system designed to expose the test subjects to aerosols. Click the image to enlarge it. Whether gases, aerosols or dusts are generated, a supply-line for the test article is ligated into the air supply line feeding the exposure chamber, allowing for the control of the concentration within the chamber by the scientist – something that must be actively monitored throughout experiments.

Whole-Body and Nose Only Exposures

Inhalation studies can use ‘whole-body’ chambers where the animal’s whole body is exposed, or ‘nose- or head-only’ chambers which in some instances have become the preferred method due to their increased specificity to the respiratory tract. A potential drawback of using Whole-Body chambers is that test subjects – usually rodents in the process of grooming themselves can orally ingest the test material by licking their fur coats.  ‘Dead space’ within whole body chambers is also a drawback.  The accompanying picture shows how a rodent sits in a ‘restraint‘ tube during exposure.  An important key to properly running inhalation exposure experiments, is making sure that animals are adequately acclimated to the tubes and are comfortable in them for extended periods of time.

The accompanying photograph shows a Nose-Only inhalation exposure chamber with all of its exposure ports occupied by the restraint tubes for rodent species. Click on the image to enlarge it.  The picture further shows how the number of animals exposed can be increased by stacking multiple chamber levels and increasing the total number of exposure ports.

Depending on the questions being asked in that particular experiment, exposures can range from: hours, to days, to weeks, to months and years. During and afterwards, any number of toxic or therapeutic biological responses can be measured including changes in: clinical signs, body weights, blood chemistry, clinical chemical parameters, and changes in organ weights and tissue microstructure (histopathology). Again, collectively these are a very technical set of experiments to run, and which require a very specific and unique skill set.

Inhalation Toxicology Training

How can students get trained in Inhalation Toxicology? Beyond high school, students can major in Biology, Chemistry, or any of the Biomedical sciences as undergraduates where they can start receiving lab training if there are researchers at that particular university, or one close by. Further training can be obtained at the Masters or Ph.D. levels. Similar to Pharmacologists, Toxicologists and Drug Metabolism Scientists, Inhalation Toxicologists generally receive their training at major research universities.

As a sub-discipline of Toxicology, scientists looking to receive training in Inhalation Toxicology can have varying backgrounds in terms of degrees conferred. If an individual doesn’t initially train in an Inhalation Toxicology lab, they can work in these labs as Postdoctoral scientists or ‘Fellows’ with any of the Biomedical degrees, and even with ‘Medical’ and ‘Veterinary’ degrees. When I gained my training in Inhalation Toxicology, my Ph.D. was actually in Pharmacology.

Depending on the degree level earned and where the scientist is employed, Inhalation Toxicologists can earn starting salaries of $60,000-$70,000 and above. One of the themes of my posts in this series is there is a tremendous amount of flexibility and overlap in the Biomedical sciences. Upon receiving training in Inhalation Toxicology, scientists must then determine which sector they want to pursue – academia, the private or public sectors, or nontraditional careers. Scientists with this background also have the flexibility to combine their knowledge sets with other disciplines to go into a wide variety of areas in: pharmaceutical companies and biotechs, chemical companies, consulting, patent law and even starting their own companies and ‘Contract’ labs.

Toxicology For the 21st Century

It’s worth reiterating something from my Toxicology blog post and that is there’s an effort currently underway called ‘Tox-21’ or ‘Toxicology For the 21st Century’. One of the goals for Tox-21 is to minimize animal usage. Currently, there are efforts to develop methods to test for inhalation toxicity using in vitro models and cell culture preparations simulating animal tissues. Students interested in this field will position themselves well by learning about some of these advances that are on the horizon.

Thank you for taking the time to read this post, and I hope I was able to shed some light onto what Inhalation Toxicology is as a field. Similar to the other disciplines I’ve discussed, Inhalation Toxicologists have their own professional societies and meetings. While the Society of Toxicology has subsections on Inhalation Toxicology, the field has two of its own professional societies and meetings; the American Thoracic Society, and the American Heart Association as the Heart is a major organ affected by the inhalation of toxins.

The next posts in this series will talk about what Regulatory Science is, and then my personal journey towards becoming a Scientist. If you enjoyed this post you may also enjoy:

A special thank you is extended to my Postdoctoral Advisor and his lab for allowing me to learn and train in this exciting field. I also want to thank two other colleagues who will remain anonymous – very brilliant veteran inhalation toxicologists with vast experiences, who have continued to teach me about the field. Finally, I want to thank and acknowledge CH Technologies for graciously answering my many phone calls as a Postdoctoral Scientist when I was first learning how to use their inhalation systems; and also for graciously providing the diagrams and pictures of the inhalation exposure chambers, and systems used in this post.

Dr. Namandje Bumpus discusses her educational path, and her research career in Pharmacology

While black history should be celebrated throughout the year and not just in February, the month provides the opportunity to not only recognize African Americans who have made significant contributions in the past, but also those who are presently making history. As there are numerous African American scientists and innovators who are typically celebrated during black history month in Science, Technology, Engineering and Mathematics (STEM), there are also quite few African American scientists in modern times that are worth recognizing. One such scientist is Dr. Namandje Bumpus (pronounced Na-Mon-Jay), of The Johns Hopkins University. On Feb. 1, 2016, Dr. Bumpus granted an interview to discuss her background, the path to her current career, and potential avenues for under-represented minorities to get involved in STEM. I originally published this piece when I wrote for the Examiner, and two years later, I’m republishing here on my blog.

Anwar Dunbar: First Namandje, thank you for this opportunity to interview you. My writings in February tend to focus on Black History Month and as a scientist myself I want to shine the light on other African American scientists and innovators who are currently in the trenches expanding our scientific knowledge. Also being in the biological sciences versus the information technology and robotics fields, it’s not so obvious to the lay person what a pharmacologist is, so for all of these reasons I thought about you. With those things being said, let’s start.

Talk a little bit about your background. Where are you from? Were there any scientists in your family who you were exposed to at an early age? Were you always interested in science? If so, was it always biology or were you good at other parts of STEM, mathematics for example?

Namandje Bumpus: I was born in Philadelphia, but grew up in western Massachusetts. There were no scientists in my family. I had an uncle who spent some time working in a lab as an undergraduate student. He wasn’t a scientist, but he still talked to me about how he enjoyed working in the lab. Hearing about his experiences working in a lab was interesting to me. Early on I liked chemistry. My parents and others in my family started getting me chemistry sets when I was in elementary school because I started vocalizing that I thought science would be something interesting to do.

I worked through them (chemistry sets) and I really liked it, and when I was ten (pre-email), I actually wrote a letter to the American Chemical Society to ask about information for careers for chemists. They sent me back lots of brochures and a letter discussing things you could do with a chemistry background. That really got me even more excited just having all of that information and starting to dream about the things that I would do. So I was really more chemistry focused until high school when I finally took a physiology class, and then realized that I wanted to lean more towards biology and physiology.

AD: Talk briefly about your educational path. We overlapped at the University of Michigan’s Department of Pharmacology. How did you get there? What got you interested in research?

NB: I went to Occidental College, a small liberal arts college and did some research there. We didn’t have many labs so I was doing plant research and I really liked that, but I thought that I wanted to do something that was more directly related to human health and physiology, so I started researching certain fields to see what that would be. I came across Pharmacology and it was something that seemed interesting, so the summer after my junior year, I applied for summer research programs in Pharmacology so I could try it out.

Michigan had a summer program called the Charles H. Ross Program for African American undergraduates to come and work in the Pharmacology Department for a summer, so I applied for that and I got it. That summer before my senior year, I had a really great experience in the department in general. I worked in Dr. Richard Neubig’s lab, and they gave us a short course where I was introduced to the principals of Pharmacology. That really sold me on Pharmacology and since I also had such a great experience in the department, I became really interested in going to the University of Michigan for graduate school.

AD: Not a lot of people understand what doctoral training is like and what it entails. You chose the lab of Dr. Paul Hollenberg which was a Cytochrome-P450 lab and we will discuss that, but what was it like learning how to do research? For example, what was the question you were looking to answer through your thesis project?

NB: In my project I was specifically looking at how genetic variances and mutations that existed in the population could impact their ability to metabolically clear certain drugs that are used clinically. We focused on a drug used to treat depression called Buproprion, and we looked at an HIV drug called Efavirenz. So I was looking at how genetic mutations could affect clearance of the drugs, and how those genetic variances might impact different people having genetic differences in drug-drug interactions.

AD: So would that be in the area of Pharmacogenomics?

NB: Yes.

AD: So as a Postdoctoral scientist did you work on a similar project? Or did you go in a completely different direction?

NB: Yes, my postdoc was somewhat different. I was looking at how lipids and fatty acids are cleared and how we regulate that process. Specifically, I was trying to find which pathways in cells were responsible for the metabolism of fatty acids. In particular, we were interested in stress activated pathways and seeing how activation of these stress pathways impacted expression of Cytochrome P450s that were responsible for metabolism of lipids.

AD: So right now in your own lab, what are you all working on?

NB: Lots of different things. The major focus has still been P450s, but looking at two different areas. The first is seeing how P450s and their metabolites contribute to drug induced toxicities, and to see if there are ways we can mitigate toxicities. We’ve had a focus on drug usage through HIV. The other side of my lab has been helping in collaborative clinical teams to develop drugs for HIV prevention, and trying to figure out how people’s pharmacogenetic variances in drug metabolism can impact their therapeutic responses when they are taking drugs used for HIV prevention.

AD: Now just briefly, from your doctoral studies through your postdoc, were there skills that you had to develop or did you come ready to go with everything? What were your major learning points as you worked through your thesis and your postdoc?

NB: My postdoc was really different. The experimental tools that I learned during my dissertation didn’t really help with what I wanted to do in my postdoc. I wanted to learn something new. Obviously the thinking and knowing how to design experiments was translatable. In graduate school I was doing a lot of mass spectrometry, more chemical-type techniques, and more biochemistry and enzymology. In my postdoc I was doing more in vivo biology and physiology, so I was using mice for the first time. I had never worked with a whole animal before. So I had to do a lot of cell isolation experiments and injections, things I had never done before; so I really had to learn a lot of new techniques for my postdoc. Now in my lab its great because we’re able to combine all of that, so we do a lot of mass spectrometry, biochemical techniques, in vitro mechanistic stuff/enzymology, as well as a lot more whole animal work, and a lot more whole cell work, things that I picked up in my postdoc, and I was able to combine both skill sets to build my program.

AD: And you did your postdoc at?

NB: The Scripps Research Institute.

AD: Did you always have the leadership skills necessary to run a lab or did you have to learn them? Was it a work in progress?

NB: Yes, you always build on it and it’s still a work in progress. I think you don’t necessarily get trained for it in graduate school or as a postdoc, but I tried to participate in things that were extracurricular; the Association for Minority Scientists at Michigan, and in my postdoc I was a part of our postdoctoral association, so I tried to pick up leadership skills by being involved in those other groups; but even still you’re not prepared to run your own lab. You really learn it as you go; you try things to see how they work. You talk to senior colleagues to get their advice and potentially go back and try something else. You take mentorship or leadership classes which I’ve done too, but I think it’s always a work in progress.

AD: We’re almost done. For the lay person, what are Cytochrome P450s and why are they important?

NB: They are proteins expressed in our bodies in all tissues, but mostly in the liver. What they largely help us to do is clear foreign compounds from our bodies. So for instance, if you are taking a drug therapeutically, you take it orally and you swallow it, one of the first places it’s going to go is into your liver. Your liver doesn’t want it to hang around and be inside of your cells forever, so we have these proteins that will change (biotransform) these drugs structurally to make them something that can be removed from your cells and removed from your liver. Thus, P450s are proteins that help us to clear foreign compounds and molecules. Drugs are obviously a large percentage of the foreign compounds that we’re exposed to, so we call them drug metabolizing enzymes.

AD: All of us went different routes after leaving Michigan. Some landed in the private sector in big pharma or the chemical industry. Others like myself, went into the public sector on the regulatory side, and I think I’m one of the only ones from our department to do that. A large chunk of our graduates went into academia which requires a ton of skills: leadership skills, entrepreneurial skills, and teaching skills. It’s also a very competitive environment and I very much admire my peers, such as yourself, who went that route. What made you decide to go into academia as opposed to the private sector or some other track?

NB: I think academia is the only thing that really fits my personality. I really like interacting with and training students. I like having a really close relationship with them where they come and work in my lab for several years while they work on earning a Ph.D. I get to see them grow. It’s similar with postdoctoral fellows. They come to the lab for a couple of years and I help them try to get to the next stage in their career.

I really love the educational aspect of the training. Additionally, I really like the broader training environment. In addition to my associate professorship, I’m also associate dean in the area of education where I get to spend a lot of time with graduate students who aren’t in my lab. I work more broadly with other graduate students helping them decide which lab they should choose for their thesis, and what they want to do next with their career. I further help them identify training opportunities for careers that they might want outside of academia. I really enjoy education training so this is the place for me.

Also, I like that scientifically, if I can dream it I can do it. If we have something that I really want to test in my lab, we can find a way to do it and test it out. I like the autonomy and the ability to be that creative with our science as well, so I think it’s a really good fit for my personality and goals.

AD: Now lastly, what advice would you give to young African American girls or those who are curious about science, but not sure that they can do it, or parents who are reading this and want to expose their kids to science?

NB: I think first knowing that if it’s something you really want to do, then you can do it. I think what’s most important about being a scientist is the passion for it and the interest. It’s not about everyone thinking that you’re brilliant. It’s about being interested and being a curious person and organically interested in science. I think it depends on which stage you’re at. If you’re in elementary school, starting off like me getting chemistry sets and microscopes is a good start – getting kids the type of gifts that will stimulate their interest and curiosity in science. Make them see that they do have the ability to do experiments and explore things on their own, and I really think that can get them even more excited about it. Microscopes, chemistry sets, and telescopes, those are things you start with from five years old.

Often times there are summer camps. At Johns Hopkins we have summer programs for people, middle school students and high school students. At many different stages you can contact local universities and museums to see if they have summer camps for science that kids can go to and that can be helpful. A lot of schools including ours have high school programs. In ours you can spend the whole summer working on a project and I think that’s a great way to see if you like scientific research and really get excited about doing research; so I think there are a lot of opportunities. You just have look out for them. The best place to start is contacting local universities and museums. Most universities will have a community engagement program you can contact for opportunities.

AD: The last question, Namandje, involves something personal you shared with me. The science community recently suffered a great loss, someone who was a mentor to you. Would you like to say a few words in memory of this individual? From what I gather, this person was also a female African American scientist.

NB: Sure. Her name was Dr. Marion Sewer. She was a full professor at the University of California-San Diego, and a Pharmacologist as well. She worked on endocrinology and really did a lot to understand the endocrine system and how it impacts lipid metabolism.

She was just a very highly regarded scientist and she was also someone who cared a lot about outreach. She ran a lot of programs that were focused on diversity and giving opportunities for people in high school through undergraduate school, and really spent time with postdocs to make sure there were really opportunities for people of different backgrounds, including African Americans, particularly for African Americans to have exposure to science. She was someone who was a really great colleague, a really great scientist and someone who also, in a rare way, really cared about people, service, equity and inclusion in science. She really inspired me and helped me to get my first National Institutes of Health (NIH) grant by reviewing it for me several times. She was more senior and experienced, and I think a lot of us have that same story where she helped us get started because she was so generous with her time, so it was definitely a really big loss.

AD: Well thank you for this interview opportunity, Namandje, and your willingness to discuss your life and career. A lot of people will benefit from this.
