All Roads Lead to…Data Science?

By David Crocker

I’m a Data Scientist at the National Renewable Energy Laboratory and I’m doing work in a job that didn’t exist when I was born.  It took me a long time to get to where I am, but eventually I did it.

I went to a public high school that had a few really good teachers and I was able to learn a little bit of Calculus before I graduated.  I got into a great university, UCLA, but I wasn’t prepared emotionally to do what it took to get through College.  There were really three reasons for my dropping out.  I lived far away and couldn’t afford to move closer, so I rode the bus for four hours a day.  When you are in college you have to spend a lot of time studying, and I didn’t know how to stay focused on my homework back then.  Also, when I went to college I realized that I would never be a doctor and I was deeply disappointed.  You see, I didn’t know about how many interesting jobs there were out in the world.


So I dropped out.  And I worked laying carpet, I worked in factories, and I worked at convenience stores.  But I never felt like I fit in.  I was curious about the world.  I always wanted to know how it worked.  I read a lot of books that had exciting ideas.


So after I got over my own disappointment at where I was in life, I started to go back to school.  I went to a community college, El Camino College, in Torrance, California.  I decided that I would study Electronics, and I really began to study hard.  When my friends were out partying all night, I would leave early and go study, or get sleep, so that I would be ready.  I worked evenings and nights at a convenience store to pay for my rent and food.  I got a cheap car, but I rode my bicycle whenever I could to save money on gas.  It was hard, but it was also some of the most fun that I had ever had.  I was surrounded by people that cared about ideas in the same way that I did.  I graduated with an Associate’s Degree!


Then I got a job building satellites.  I was working on and touching things that ended up in geosynchronous orbit, and one even went to Mars.  I wasn’t good with my hands the way that so many of my coworkers were, though.  So I started to plan the production of satellites.  I was translating blueprints into instructions for building microwave integrated circuitry modules that sent radio, television, and data around the world.


But things couldn’t be easy, could they?  No.  The company that I worked for had stiff competition, and for a lot of reasons, that work dried up.  Luckily, I was paying attention to current events and I saw it coming.  A lot of my friends were spending money and going into debt, but I started saving up and paying off every debt that I had.  Then I moved to Denver, Colorado.


I didn’t have a permanent job.  I worked at a lot of temporary office jobs, and soon I had a reputation as a solid worker.  But I knew that I wouldn’t be happy if I didn’t keep striving.  So I quit and enrolled at the University of Colorado at Denver.  I took out student loans for the first time in my life, but it took months before I started receiving the money.  At one point, I ate rice and beans for a solid month.  I had to borrow money from my parents, and it was humiliating.  But I paid them back as soon the money came through.  I got rid of my car and rode a bicycle everywhere in every kind of weather except ice—I learned that the hard way.


I love History and English, and I was thinking that I would get a degree in one or the other, but part of my degree required that I take a class on science for non-majors.  The professor that taught that class changed my life.  Dr. Robert Damrauer was able to teach Chemistry in a way that students without a deep background could really understand.  He convinced me to switch majors to Chemistry, he gave me a job in his Organosilicon Research Laboratory, and soon I was supplementing my income with money I earned doing science.  I owe Dr. Damrauer a debt that I can never repay.  He, and the Chemistry Department faculty supported my studies in a way that was both personal and professional.  They didn’t just teach me.  They cheered me on.  They corrected me when I made mistakes, and they gave me feedback that I needed.


I focused my effort on school and staying in shape.  I lived as cheaply as I could stand, and I made friends who studied together.  We quizzed each other, and when one of us got the material and others didn’t, we would explain it to the others.  Sometimes people who are smart and motivated don’t make friends because they are too busy competing with each other.  But that is a mistake that we worked hard to overcome.  We worked together, we studied together, and we shared our knowledge.  We competed with each other, too, but when someone else did better, we congratulated them, and we meant it.  The wisest thing that I ever did in college was to surround myself with people that were smarter than me, and help them however I could.


After I graduated I got a job installing and repairing scientific instruments.  I travelled for several years and went to hundreds of laboratories all around the country.  I worked in laboratories that tested food flavors, water and air quality, pesticides, and even chemical weapons.


After several more years, I realized that I still wasn’t doing the jobs that I was best suited for, so I went back to get my Master’s degree in Computer Information Systems.  I had programmed for fun in high school, and had taken several college courses, but it was time for me to get serious again.  I was working and took evening classes to get the degree, and it was very expensive, so I made sure that I finished.


This led me to a contract and then a job with the National Renewable Energy Laboratory (NREL) in Golden, Colorado.  Now I work to integrate software and help other scientists with publishing their research and their data.  And one of the most important things that I am doing is making it possible to make our data available to the public.  Every federal agency, and many state and local ones, are now trying to make data available for free to the public.  This will change how the worlds of science and of government work because individual citizens will be able to use it to understand the world through science.  It will lead to new inventions and new businesses.  It will help ordinary people make sure that their governments are doing the right things.


I didn’t go straight through college like some of the other students in my high school did.  But I never stopped trying to learn new things.  I worked hard, and I still do, but a lot of people have helped me out.  I couldn’t have done it without some great teachers that invested their time and effort in me.  I couldn’t have done it without taxes getting invested in my schools and colleges.  For many years my jobs didn’t pay very well, but they were always interesting, and I always got by, and I always felt like I was doing something that made the world a better place.


A Lifetime of Curiosity

by Robert (Bud) Talbot, PhD

Dr. Talbot’s STEM of choice is Science with a focus on physics education. He now works for The University of Colorado Denver, as an assistant professor of science education in the School of Education and Human Development. Dr. Talbot helps to recruit and train new secondary school science teachers, and does research on teaching and learning science at the university level. In his spare time, outside of work, Dr. Talbot loves to run, work with technology (especially amateur radio!), engage in citizen science projects, and do sciency things with his 6 year old twin daughters. If there was one thing he wished he had known before college about STEM, it would be “how being scientifically literate shapes the way you do anything and everything in the world!”

He studied for many years to get where he is, first at Indiana University for degrees in Geology and science education (BS and MS), then at the University of Colorado Boulder for a PhD in science education, researching how to develop tests and surveys to be used in science teaching and learning.


My bio is above, but that is not who I am. Here’s the truth about me: I’m a geek and I’ve always been a geek. I love geeky things like technology, computing, and amateur radio. But I also love to be active. I’m totally obsessed with running and I love to dig deep into all of the data related to my running: GPS tracks, heart rate, power output, pace- lots of numbers! All of this geekery was instilled in me early on. I was lucky enough to grow up in a family where we spent a lot of time outdoors, camping, hiking, taking crazy roadtrips. Did I mention maps? I LOVE maps. They are everywhere in my house. Anyway, back to my childhood. My mom told me that I once went to the public library at the age of 6 and asked for a book on “splitting atoms.” Of course I don’t recall that, but I bet it was a cool book. I didn’t know it at the time, but I was well on my way to being a science teacher.

Materials and Methods

Degrees can only tell you so much about a person’s STEM career, here’s my actual journey: I thought I wanted to be an accountant when I started college. My brother in law was an accountant and I really looked up to him. But the classes turned out to be really boring! Then I discovered Geology. What fun! Maps, rocks, lots of camping and hiking. That was the best. So now I was on my way to being a geologist. Well, I ended up taking a few years off from school before finishing (long story…) during which time I realized that my true passion was trying to help others see how cool science was. I was always asking questions and getting others to geek out with me. So it seemed natural that I should be a teacher!

I went back to school and became a high school physics and Earth science teacher. It was a great experience, and I was fortunate enough to learn a lot and build lasting relationships with many of my students. I know that my work made a difference. After seven years of teaching, I yearned for more learning and to work with teachers, so I went to graduate school in Boulder. It was there that I learned about research on teaching and learning, which prepared me for the job I now have as a professor.


Right now, I am focusing on undergraduate science education at my job as an assistant professor. We help other professors to think about better ways to teach biology, chemistry, and physics at the university, and investigate the impacts of innovative teaching on how students learn. Our main focus is to help students in these courses succeed and become prepared to pursue their future goals. Our work is making a difference!


I love science education, and especially physics, and here’s why: it really helps me to see how important it is to have a scientific worldview. I can apply scientific reasoning to any aspect of my life. Not only is that fun, it is useful. Many of the skills and dispositions that we use as scientists (like curiosity, research methods, and writing ability) are useful in all aspects of life. And my interest in physics and Earth sciences lets me do lots of fun things in my spare time, like amateur radio (my callsign is W0RMT), and participating in citizen science projects (check out CoCoRaHS, mPING, CWOP, SETI@home, and LHC@home).

Science is everywhere, and it’s fun and useful. It leads to a lifetime of curiosity!   

Canis lupus familiarus: A ridiculous story of artificial selection

By Dr. Debbie Rook


“Natural Selection” is a complicated and intricate biological concept that often trips up the most educated and well-read among us. To get to that, we’re first going to start with something we all can relate to and understand- specifically, breeding or “artificial selection”. This means specifically that people are the selecting what traits are passed on to the next generation, instead of nature.

Think of a dog, any dog. You may know a chihuahua down the street or your great aunt’s mastiff. Dogs come in amazingly different varieties, different sizes, weights, strengths, hair, tails, ears, noses… you name it! You probably have heard that the dog came from wild wolves, which even look like a few breeds (huskies and malamutes, mostly). But how did we get there? How is that even possible to get so much change in just a couple of thousand years?

Artificial selection is the answer. Back in the days long ago (around 130,000 years ago), there were likely wolves that hung out around farmers or nomadic tribes because there was easy food to get- whether it be cattle or other farm animals, the rabbits that came to eat crops, or simply leftover scraps that were either discarded or given to the wolves willingly. Over time, the wolves that had a nicer temperament (less biting, better smiles), would be given more scraps (think if a stray dog came up to you at a park- would you share your ham sandwich if it was growling at you or cuddled next to your side?). This was the beginning of a beautiful relationship between the more tame of the wolves and the humans. Now, how was this really selecting? The humans were not breeding these dogs yet, nor were the animals even living with them, so how could that change the population? Simple- food. The nicer dogs are more likely to get scraps from the humans, and therefore more likely to survive the winter and reproduce, while the mean wolves got no scraps and had to fend for themselves. Slowly over time, the scrap-grabbing would change into cohabitation of tame wolves and humans, which would allow those dogs to have even more offspring, because they were being actively cared for by the humans. And that’s how you get dogs! Bring a nice wolf into your house and in a couple (hundred) generations you’ll have yourself a dog (but don’t try this at home…).

So that’s great, a slow change in the population over thousands of years got us from nasty predator wolves to tame live-in dogs. But how did we go from wolf-like dogs (big, sharp teeth, long noses, pointy ears) to all the different kinds today (big/small, variable teeth, long/short/pug noses, pointy/droopy ears)? That is where serious artificial selection comes in, breeding.

Say you are a farmer and need a dog to look after your flock of sheep. You start with the basic wolf-dog and you select for traits that you want. Specifically, you want a dog that is kind to you and your sheep but will scare away other animals. So you take all your dogs and find the ones that meet those criteria best. They won’t be perfect yet, maybe it will sometimes snap at you or a sheep, but otherwise just likes to chase off coyotes. You mate the two together that have the best traits. Those offspring then will have a smaller range of these traits closer to your ideal. It’s possible that in one generation you will have succeeded with at least one of the dogs, but if not you just try again with the next breeding cycle. This also works if you need a dog to pull a sled, or find foxes, or cuddle with your kids, or even carry in your purse. Slowly, over a few generations you can get a lot of change in these animals.

I’ll give you one more example because I think it is so cool. Bull terriers. Bull terriers are known for their noses that are shorter and angled downwards. Here is one:


This is a very dramatic feature, so you’d think that it would take hundreds or years to get a nose like that from a regular looking dog. BUT…

Here is a bull terrier from 1915.


And 1918 (for good measure).


You can see that those noses have changed a lot in the last hundred years. The 1918 picture also shows you a little how this works. If you look at the four dogs, they are all bull terriers and likely related, but there is variation (differences) between the noses. Specifically, the second from the left has a nose that is slightly more downturned than his siblings. If you were trying to make the modern bull terrier, he is the dog you would want to mate to get the next generation.

So you can see that in a few decades you can get dramatic changes in breeds of dog, all by having humans select traits that they like the most. Selective breeding has brought about the multitude of types of dogs that you see today. Hopefully you have a better understanding of this now that you’ve seen it in action!

Next time: nature takes a crack at selecting for different animals, incredible variation, and adaptation occurs.

The Zika Virus (#1)

By Lauren A. R. Tompkins

A collection/series of blog posts entitled:

The Zika virus pandemic – insights from a scientist

The past few weeks (March 2016) have provided major advances in our understanding of Zika virus through publication of several key research studies. In the wake of the global response to the Ebola virus outbreaks, measures to expedite research and prevention strategies for Zika virus are now underway. Emerging infectious diseases, which manifest outbreaks without warning and often without the presence of effective control measures, are dramatically affecting how information is shared between scientists and how prevention strategies, such as vaccines, are regulated. In a time of public health crisis, the scientific community has pulled together with the common goal of a rapid response to combat Zika virus.

 First blog post for this series, entitled: The politics of Zika virus

             On Monday (April 11, 2016), Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases (NIAID), and Dr. Anne Schuchat, principal deputy director of the Centers for Disease Control and Prevention (CDC), addressed reporters at a White House briefing. The topic of discussion was Zika virus and an appeal for the necessary funds to prepare for mosquito season, when the virus will likely spread to the southern United States. According to the CDC, at least 346 people from the continental United States have been infected with the virus, mainly through travel-related exposure. However, with the summer months approaching, and mosquito populations expanding with warmer weather, local transmission of Zika virus is likely to occur.

A gridlocked Congress is not an unusual concept to the American people. Still, a “public health crisis of international concern”, as stated by the World Health Organization (WHO) in February of this year, should theoretically hold weight if politicians continually claim to have the best interests of Americans in mind, let alone the public health of all inhabitants of our planet. Unfortunately, Congressional Republicans are tightening their wallets and stubbornly resisting the allocation of necessary funds for combating Zika virus. Rather than listening to knowledgeable scientists and public health officials, pleas for appropriations are falling on deaf ears. Indeed, President Obama has asked Congress, again, for the full $1.9 billion dollars that is required to fuel Zika virus research. On Tuesday (April 12, 2016), Congress approved a bill to provide financial incentives to companies to develop treatments for Zika virus infection, although no funding was provided. Currently, roughly $600 million has been diverted from the Ebola virus funds towards Zika virus research.

Let me pause here to let the following concept sink in: now that Ebola is no longer a potential threat to the United States, it is assumed that the rest of the world can handle the fallout itself…but, that doesn’t seem to be the case. Dr. Margaret Chan, WHO director-general, announced in January that although all known chains of transmission in West Africa had stopped, including the most recent outbreak in Liberia, new flare-ups are likely to occur. This will require a sustained response for prevention of future outbreaks. Indeed, Sylvia Mathews Burwell, U.S. Health and Human Services Secretary, told reporters, “We face two global health challenges, Ebola and Zika, and we don’t have an option to set one aside in the name of the other.” The decision to pull money from the Ebola fund is somewhat analogous to withdrawing military troops from countries where the United States has intervened and then pulled out, for one reason or another, hoping for sustainable change in those regions. Historically, this system doesn’t seem to work, and furthers the global opinion that Americans don’t care about non-Americans.

There is a comical phrase among infectious disease scientists: “ATM diseases” get the money. Essentially, the majority of funding is allocated to AIDS/HIV, tuberculosis, and malaria research, which some say are “sexy diseases” as they engender public attention. We know that these diseases are incredibly important to study and combat, but when funding is limited, research on other diseases stalls. Why don’t we know that much about Zika virus? It didn’t cause outbreaks until recently. This is the problem with emerging pathogens: they burst forth rapidly when we don’t have the tools to control them. The scientific community is now scrambling, working around the clock to learn as much as possible, as quickly as possible. $600 million sounds like a great deal of money, but it is nowhere near enough to fight Zika virus, as Dr. Fauci reiterated on Monday.

Pull-quote: “When the president asked for $1.9 billion, we needed $1.9 billion.” – Dr. Fauci, NIAID

One day several years ago, as a novice virologist, I was star struck when I met Dr. Fauci during one of his routine visits to the laboratories of the NIAID. The first thing I noticed was Dr. Fauci’s notorious New York accent, the second, his calm demeanor, humility, and compassion. His lectures inspired me, giving me great faith in the leaders of our scientific community. Why this faith is lacking in our Congressional leaders is nonsensical to me. If we cannot trust those we have appointed to run programs ethically and passionately, then what is the point of having these leaders?

Pull-quote: “Everything we look at with (Zika) virus seems to be a bit scarier than we initially thought.” – Dr. Schuchat, CDC

The NIAID and CDC, institutions that preserve public health in America, are not the only scientific leaders voicing the urgency of combating infectious disease outbreaks before they become uncontrollable pandemics. The WHO has also emphasized the potential consequences of a Zika virus pandemic. Indeed, although Zika virus is an old virus (it was discovered in 1947), it emerged as a rapidly spreading pathogen causing sizeable outbreaks in recent years. In the span of about one year, 440,000 to 1.3 million Brazilians have been infected with Zika virus, which has spread to at least 33 countries. At this point, the association between Zika virus infection during pregnancy and microcephaly, a condition among infants resulting in a smaller than normal head size, has essentially reached causality. That is, scientists can definitively and causally link the virus to microcephaly. [In subsequent posts, I will present some of the important research rocketing into publication regarding this issue.] In addition to microcephaly, the WHO acknowledges that Zika virus infection likely causes Guillain-Barré syndrome, an autoimmune disorder in which a person’s immune system attacks his/her own nerves.

Science is not devoid of political influence. Granted, financial resources are not endless, but history has shown the rapidity with which infectious diseases can spread and the devastation that follows. We were not prepared for Ebola virus, which claimed the lives of over 11,000 people. Will the necessary funding come for Zika virus research, or are we destined to continually ignore potential public health crises until it’s too late to combat them?

Hot and Spicy Chemicals

By Dr. Doris Kimbrough

You grab a bag of corn chips and a bowl of salsa out of the refrigerator and settle in to watch TV. The salsa is hotter than you expected and after about five chips, your mouth is on fire. Big gulps of ice water don’t help, so you head back to the kitchen to look for sour cream or a glass of milk. What is going on in your mouth? How can cold salsa from the fridge burn your mouth? Why doesn’t cold water help the way it would for hot soup or hot tea? How does the sour cream or whole milk solve the problem?

To answer these questions we have to look at some special nerve cells (neurons) and the chemicals found in hot peppers. In addition to the nerve cells that help you move (motor) and control body functions (autonomic) you have lots of different kinds of sensory nerve cells. Sensory neurons are responsible vision and hearing and all your other senses. There are many different types of neurons involved in touch. Some can detect pain; others respond to pressure, heat, cold, or itchiness to name a few. The nerve cells that detect heat are the ones we need to focus on for this story.

Heat detecting neurons don’t work at or below normal body temperature; think of them as sleeping until you touch a hot stove when they wake up and tell you “Ouch, pull back! Pull back!” Hot peppers like jalapeños contain a chemical called capsaicin (cap-SAY-shin) that fools these nerve cells. The capsaicin binds to the nerve cells and wakes them up. Your brain gets signals that something is burning you even though nothing that is actually hot (in temperature) is involved. There are other chemicals that can do this: piperine and sabinene are chemicals found in ground pepper and curry spices.

So why doesn’t a nice cold drink of water help with the burning? Capsaicin is a chemical that is hydrophobic—literally: “water fearing”. Capsaicin doesn’t really fear water; it can’t because it is a molecule, which cannot have feelings. However hydrophobic compounds, like capsaicin, do not dissolve in water. Other hydrophobic substances are vegetable oil, wax and gasoline. So when you gulp cold water because spicy salsa is “burning” your mouth, the capsaicin stays bound to your neuron and your brain still gets signals that your mouth is burning. Hydrophobic compounds do dissolve in other hydrophobic substances, like oils or fats. You may have heard the expression, “like dissolves like”. The fat in sour cream and whole milk will dissolve the capsaicin and remove it from the nerve cell. This turns off the signaling to the brain and lets you get on with your life.

About the author: Doris Kimbrough is a chemistry professor at CU Denver. She grew up in Atlanta, GA, and went to college at the College of William and Mary in Virginia and to graduate school at Cornell University in Ithaca, New York. She has loved science and chemistry since she was a little girl when her chemist father let her play (safely!) with stuff in his lab.

For the Love of Derby…I mean Biology

By Abena Watson-Siriboe

Who I really am-

I grew up in a family of scientists. My grandmother obtained her pharmacy degree when few women or even women of color were involved in the field. My grandfather was a Korean War vet and dentist deeply entrenched in his community. My mother is a biologist and father a chemical engineer. You can say that science was in my blood. Growing up, my family made sure to foster my interests by providing me with science kits and even a rat to dissect when I was too young to handle a scalpel. In middle school, I received a microscope that probably dated to the late 60s, but I loved it. I searched my house for things to inspect and was even tempted to take my own blood sample but eventually chickened out. Little did I know that as an adult, I would be inspecting and showing off x-rays of my ankle broken during a roller derby game. Not only am I a scientist, I’m a roller derby player who goes by the name Norah P Neffrin. You can take the nerd out of the lab but you can’t take the science nerd out of the girl.

How I got here-

When I first started my undergraduate degree, I was a philosophy major with aspirations of going to medical school. As my studies progressed and I took courses such as cellular biology and neuroscience, I realized that medical school wasn’t in the cards. I wanted to be a researcher. So, much to my parent’s pleasure, I changed my major to Biological Sciences and decided on a minor in neuroscience. One of my teachers expressed to her class that she was looking for students to conduct research in her neuroscience lab. I immediately jumped at the chance and was immediately smitten. My research involved the response of a brain region called the Supra Optic Nucleus (SON) to dehydration in rats. Most of my days were spent treating, sacrificing and preparing rat brain tissue. I would go home and my mother complained that I smelled like rat, but I loved every minute of it.

My time conducting research during undergrad inspired me to get a Masters degree, but it also required moving across the country away from family. I continued to work in the neuroscience field but my work focused on a smaller scale. My work focused on a transporter responsible for sequestering molecules such as serotonin and norepinephrine into vesicles. Small changes in the genetic script of this protein have been linked to mental conditions such as bipolar disorder. It was my hope to provide some insight into the role this protein plays in such a complicated condition. During my MS, is when I started roller derby, hence the derby name, a play on norepinephrine. Oddly, most people don’t get it.

What I do now-

Currently, I work in a biophysical laboratory at CU, Denver. My lab examines membrane binding proteins, some of which are present in the brain and or pancreas. We use varying techniques to determine what parts and under what conditions does the protein bind to the membrane. Some of the proteins we work with contribute to membrane fusion whilst others prevent it. My protein of interest prevents vesicles that contain insulin from being released by specialized pancreatic cells, potentially playing a role in diabetes. By understanding how this protein works, our work can inform potential drug targets. In addition to my work in the lab, I still play roller derby with a league ranked #9 in the world. But these days I skate under my legal name.

Passion for the subject-

As a kid, I was obsessed with how things worked, especially the natural world. It still amazes me that we’re made of atoms, molecules, cells, organs that all work together mostly in harmony. Even more amazing is how small changes can disrupt an equilibrium and result in conditions such as bipolar disorder or diabetes. It’s this wonder and hunger for answers that keeps me motivated and impassioned.

Microbes, Molecules, and a Love of Biology


by Lauren A. R. Tompkins

Lauren’s STEM of choice is Science with a focus on microbiology and immunology. She studied for many years to get where she is, first at The College of Wooster for a Bachelor of Arts degree in Biochemistry and Molecular Biology, and at The University of North Carolina for a Master of Science degree in Microbiology and Immunology, researching reservoirs of human immunodeficiency virus (HIV) throughout the human body, with a focus on the brain. She is now pursuing a career in science journalism and freelance writing. In her spare time, outside of work, Lauren also loves reading about science in the news and delving into a good research article. If there was one thing she wished she’d known before college about STEM, it would be “[that] science isn’t a unidirectional path lacking bends, turns, and forks in the road – you make your own way and figure it out as you go”.


My dad taught science to high school students for 30 years in Cleveland, Ohio. I guess you could say there is a genetic component to my interest in science, but I think it all began with an inherent curiosity about life. I remember investigating my Dad’s biology textbooks when I was a kid, perusing the pictures and diagrams with interest, reading strange-sounding words like “mitochondria” and “pulmonary,” curious about their meaning. It never ceased to amaze me how our bodies are essentially sacs of water and bones, yet our minds have the ability to reason and invent, create and love. So, understanding how the body works always intrigued me.

Materials and Methods

In high school, I took honors and advanced placement courses in the sciences, specifically in biology and chemistry. I then searched for colleges with strong programs in the sciences in the context of a liberal arts education. The beauty of a liberal arts education is in its well-rounded, holistic approach to learning. Students are required to enroll in unique courses outside of a selected major of study, often including studies in humanities, sociology, and art. At the College of Wooster, I was able to major in Biochemistry and Molecular Biology, while still taking Comparative Film Studies and Abnormal Psychology. Wooster also emphasizes the importance of solid writing skills in life and in any profession, so most of the courses I took were writing-intensive.

Each student at Wooster completes an independent study (research) project in his/her senior year. As a science major, I planned and conducted a series of experiments towards a research goal of my own design, culminating in a written thesis and oral defense. My project was essentially in drug design, under the umbrella of organic chemistry, with the aim of combatting antibiotic-resistant bacterial infection. Conducting my own research was a completely different experience from instructional lab work as part of a course requirement. It’s far more exciting to think independently in the context of one’s own work, and science truly comes to life in this way. My experience at Wooster solidified my decision to pursue a career in biomedical science.

The most memorable experience that I had in college was when I studied abroad in Australia. Some of my most cherished memories are from my time spent on the other side of the world. I still dream about the Great Barrier Reef – the color of the water, the feeling of floating in another world, the incredible creatures of the sea. In Australia, I spent much of my time in the Reef, either scuba diving or snorkeling, eagerly awaiting the next wonder the ocean held. I learned to rock climb and surf; I camped on remote islands and drove the Great Ocean Road; I sailed around the Whitsunday Islands and swam with sharks. Every chance I had to conquer a fear, I took it. I am who I am today because of Australia, and I urge every young person to try to join a study abroad program. Never pass up an opportunity for adventure!

After college, I joined the laboratory of Dr. Albert Z. Kapikian at the National Institutes of Health (NIH) just outside of Washington D.C. Dr. Kapikian, who is recently deceased, was an extraordinary scientist and humanitarian whose invention and dissemination of rotavirus vaccines has affected the lives of innumerable infants and young children. Rotavirus infection causes diarrhea and dehydration, which in severe cases lead to death. In fact, roughly 500,000 children die from rotavirus infection annually, despite the existence of highly effective vaccines. Children of developing countries largely shoulder the rotavirus disease burden, as facilities and funding for vaccine production are limited. To address this issue, Dr. Kapikian pioneered an international rotavirus vaccine program, which licenses rotavirus vaccine technology to manufacturers in developing countries for self-sustainable production. The ultimate goal of this program is to promote the distribution of affordable, life saving vaccines to children in need. I served as a manager for the vaccine program, where I communicated with licensees, provided support and troubleshooting advise during vaccine production, and performed experiments to confirm vaccine composition and quality. This experience was incredibly rewarding for me, and in commemoration, I have a framed photograph of a Ghanaian infant receiving a dose of one of our vaccines hanging on my wall at home.

During my time at the NIH, I also conducted research and published a paper examining viral molecular epidemiology, essentially characterizing strains of viruses that caused severe diarrhea in children of developing countries. I found that I enjoyed lab work and decided to continue my education in pursuit of a career in scientific research. I was accepted to several graduate programs and decided to attend the University of North Carolina based on educational and research merits as well as a generally collegial, friendly atmosphere. I joined the laboratory of Dr. Ronald Swanstrom to study the human immunodeficiency virus (HIV). Dr. Swanstrom was among the first HIV researchers who heralded discoveries in the composition of the HIV genome and viral replication strategies. My research project was centered on analyzing reservoirs of HIV throughout the human body. HIV reservoirs are currently a hot topic of study due to their significance in finding a cure to HIV infection, which is incurable, but treatable. HIV persists in the human body over long periods of time in the form of a reservoir, which is a place in the body where the virus survives, avoids recognition by the immune system, and is protected from the action of drugs that treat HIV infection. Treatment regimens are responsible for controlling most of the infection, but since they do not affect viral reservoirs, these drugs must be taken throughout life to prevent disease progression and associated pathologies.

After about three and a half years of graduate school, I realized that my career aspirations were changing, becoming refined. Although I greatly enjoyed my years at the lab bench conducting experiments, I found that reading and writing about science was by far the most interesting to me. I yearned for a creative platform to discuss topics in science to a general audience, in hopes of cultivating interest in the field so that we may improve our world through positive change. After speaking with science journalists and freelance writers, I decided to graduate from my program with a Master of Science degree rather than continue on to a doctorate, so that I could pursue a career in science writing and communication. When I think about it, I’m not that surprised that I ended up in a career centered in writing, given my history at Wooster. I am excited to embark on this new adventure, a career that suits my passions of discovering, learning, and contributing to a better world.


Right now, I am working as a freelance writer and editor in the biomedical sciences. I’m at the beginning of a career in science writing, so I’m currently building a portfolio of work. For now, my income is mostly from editing scientific articles to improve flow, clarity, and grammar. I am also contributing to blogs, composing story pitches to publications, and even doing a little creative writing. Since I am my own boss, I can choose what scientific topics to study, which opens up so many possibilities to learn about exciting new research. I also work from home and make my own hours. The greatest challenge has been in transitioning from structured to unstructured time throughout my day. I have to be self-motivated to do my job, which takes discipline and focus. At the same time, when I’m suffering from writer’s block, I can choose to do something else productive, like research new science articles, until my writing muse returns. My income is not steady as a freelancer, but I love what I do, I have a great work-life balance, and I’m always optimistic that opportunities will arise with effort and perseverance.


As I am a virologist in training, I am most interested in infectious diseases, especially outbreaks of microbes that we know little about, such as the Zika virus and its likely contribution to microcephaly in fetuses of infected mothers. With the upcoming Summer Olympics being held in Brazil at the heart of the Zika outbreaks, I am curious, and concerned, about how increased travel to the area will affect the prevalence of the virus in other regions of the world. Mosquitos are the main culprits for spreading Zika, but it’s beginning to look like the virus is also transmitted person-to-person, at least sexually. Can we control these outbreaks through the use of mosquito repellants and netting? Or are we playing with fire when we risk exposing millions of people to Zika this summer? These are some of the questions I think about addressing through writing.
