Dr. Karena Nguyen, Disease Ecologist

What is your favorite part about being a scientist, and how did you get interested in science?

The best perks about being a scientist are sparking wonder and creativity in others (especially the general public!), hearing about ongoing research in other fields, and conducting interdisciplinary research to integrate knowledge across disciplines.

During my time as a Ph.D. student, I did a variety of volunteer projects to engage members of the Tampa community. Science is for everyone, and the best scientists can and do communicate their work to the general public!

I stumbled into science the way most scientists do (I think) – completely by accident. I was set on being pre-med, but when I took Biology II my second semester freshman year, I fell in love with ecology. While everyone else was griping about the topic, the interactions between species and the environment made sense to me. The professor teaching the class noticed and took me under his wing. I started doing undergraduate research in his lab and took General Ecology a couple years later. There was one lecture on disease ecology and I still remember how it sparked these additional questions in my mind, e.g. how does the environment influence the spread of infectious diseases? I was totally hooked from then on and decided to pursue graduate school to answer these questions.

What do you do?

I am mainly interested in how environmental factors, especially temperature, influence interactions between parasites and their hosts. For my dissertation, I studied a human parasite, Schistosoma mansoni, and its intermediate snail host, Biomphalaria glabrata. The parasite must infect a snail before it can infect humans, and I examined how temperature influenced the parasite at various points of its life cycle, in addition to how temperature affected infected snails over time (see figure). I combined published data and laboratory experiments with mathematical models to predict how disease transmission may shift in response to changing temperatures under global climate change conditions.

What are your data, and how do you obtain them?

For my dissertation, I used a combination of published data and data from laboratory experiments to simulate how changes in temperature influence the parasite and its intermediate snail host.

How does your research contribute to the betterment of society?

Infectious diseases of humans and wildlife are increasing due to complex interactions between human population growth, changes in agricultural supply and demand, and global climate change. For example, human population growth is driving increases in agricultural development and accelerating global climate change. As more habitats are cleared for farmland, the likelihood of humans encountering wildlife that carry infectious diseases will likely increase. Global climate change may also influence how easily these diseases are spread between humans and wildlife. Thus, the broader goal of my research is to improve predictions of disease spread so that the public health sector can improve the timing and application of intervention methods. By examining how one part of the puzzle affects disease transmission, we can disentangle what to expect in the future as interactions between humans, animals, and environment continue to change.

Niba Nirmal, Plant Geneticist, PhD Candidate, Creative

Processed with VSCO with al1 preset

I’m Niba and I create notes about science (biology, especially plants!) and style (fashion, makeup, skincare)! I write in a physical journal, share photos on Instagram, and create videos on YouTube. I have always loved science – logical thinking, rationalizing answers, learning how to learn—and I also love style—fashion, beauty, skincare, modeling. As a scientist, I am taught logical thinking and rationalizing while cultivating a desire to learn. However, my life as a model is based on fashion trends, creating beauty, and skincare health. For a long time, these concepts existed as incompatible, separate parts of my personality. As I continue my journey as a female scientist and young model, I have integrated the different parts of my life to create my own distinct and compelling self. As I learn more about science and style, I would love for you to join me on my path at Notes by Niba . I’m now modeling, blogging, and beginning my third year as a PhD student studying the genetics of plant development.

I have always loved the process of learning, which led me to the scientific method. The scientific method can be applied to literally everything – working out, training my cat, as well as my experiments in the lab. In lab, I’m discovering how plants express genes to grow and develop. I am trying to understand how a gene control module puts tissues in the right place. This is a huge question in development because proper developing needs careful gene expression in time and space. Because gene networks control every biological process, my research benefits many other fields. For example, many human diseases are caused by impaired networks (ex. Cancer).

Specifics: My research looks into the SCARECROW plant gene, which forms two tissues – the cortex and endodermis. This is done by a certain kind of cell division, where one cell becomes a cortex cell and the other becomes an endodermal cell. Without the SCARECROW gene, the original cell never divides and is just one fat mutant cell that acts like BOTH a cortex and an endodermis at the same time. Just like how the SCARECROW in Wizard of Oz doesn’t have brain tissue, these plants are also missing a tissue. But we don’t know what the proper SCARECROW expression is to form these two tissues. My research is to determine what kind of SCARECROW gene expression–not just the amount but also at what time–is needed to form cortex and endodermis. By using existing gene modules, I can create different gene circuits to figure out what kind of SCARECROW expression will make the cell divide and get the proper tissues in plant roots. I can see this division in real time in living plants with a super powerful microscope in my laboratory.

Plant research is essential, resulting in drought-resistant food crops, more effective medicines, clothing and fashion, etc. More than 30 THOUSAND plant species are medicinally used (ex. anti-cancer drugs and blood thinners). The world’s food supply is under threat due to population growth, water scarcity, reduced agricultural land, and climate change. As potential biofuels, plants are also important as a potential source of renewable energy. That means it’s critical to be able to detect, learn from, and innovate with our green plant friends. Our past, present, and future depends on plants.

As a scientist, I am pushing the boundaries of what humanity knows – it’s an incredibly fulfilling job and I am grateful for this privilege.

Riley Black, Science Writer & Paleontologist

What is your favorite aspect of being a scientist, and how did you get interested in science? 

Science thrives on curiosity. Even though we can talk about Science as an apparatus of journals, schools, and theories, basic questions like “What’s that?” are what draw us into a richer understanding of nature. For myself, dinosaurs were my introduction to science. I wanted to know everything I could about them from the time I was little. I wanted to know how they moved, what they ate, why they dominated the world for so long, and more. And while a career as an academic paleontologist wasn’t in the cards for me, I’m glad that writing about the past gave me an alternate route to engage with paleontology and contribute to the field in my own way.

What do you do?

I’m a writer! My career is centered around writing about paleontology and the animals the science studies, which means I freelance for publications such as Smithsonian, Slate, and Nature when there’s something neat to say about prehistoric life. I’ve also written several books. Written in Stone, My Beloved Brontosaurus, and Skeleton Keys are fossil-based books for adults, while Prehistoric Predators is a children’s book about ancient carnivores. And I’m just starting a new adult-audience book about the mass extinction that ended the Cretaceous. The flexibility in my career also lets me go out on fossil expeditions, and I’ve been going out every summer since 2011 to join different museums and universities all across the American west to help them find and excavate fossils. I never expected to become a writer, but searching for old bones is what I’ve wanted to do since I was a kid.

A Brachychirotherium track Riley found!

What methods do you use to engage your audience and community? 

There’s no single way to best communicate science. The methods that work in a museum, a podcast, Twitter, a book, or a talk are all different. And that’s what’s wonderful. There are so many ways to tell stories about science, who engages in the quest, and what questions we most want to know. My biggest bit of advice would be to think about your format and audience. Who are you trying to reach? What stories do you want to tell? Connection can take many forms, and simply keeping that goal in mind can have a huge difference. Science isn’t an Answer or a dictate. It is, and should be, a conversation.

How does your research and writing contribute to the understanding of paleontology?

We often think of the past almost as an alien world. We focus on the strange and unusual. But the fact of the matter is that the world around us today evolved from times of the past, and we can trace everything around us through Deep Time. Every species alive today has connections through the fossil record, for example, and we can look at how organisms in the past reacted to issues we face today – from forest fires to sweeping climate change. I see my role as an interpreter of these stories. I want to remind people that we have an inextricable connection to our favorite extinct species and that a richer view of the past helps us appreciate the world we’re now in. I also try to comment on how science gets done and changes through time. Science is done by people, after all, and that means the history of paleontology and how the science is conducted is just as important as its results.

What advice do you have for aspiring scientists?

Ask questions. Not only of what you want to know, but about the paleo pathways you might travel. There’s a common misconception that becoming a professor or curator is the pinnacle of paleontology and what everyone aspires to. This isn’t true at all. Some of the happiest paleos I know are collections managers, preparators, mitigation paleontologists, or have taken positions outside the tenure track lane. And paleontology offers many opportunities to stay involved even if studying fossils isn’t your career. The field thrives on amateur expertise and assistance, from searching for new fossil localities to assisting in museum collections. Whatever you do, don’t listen to anyone who tries to tell you that there’s only one way to be a paleontologist or that you need to give up your identity to fit a certain mold. There are so many ways to engage your wonder about ancient life, and the greater the diversity of voices in the field the stronger our understanding will become.

Madison Elsaadi, Neuroscientist

What is your favorite aspect of being a scientist, and how did you get interested in science?

I’ve basically been a scientist since I was a kid, it wasn’t until college that I began to consider science as a career path.  I’ve always been curious about the world, and even today my favorite part about being a neuroscientist is knowing that I’m at the forefront of human knowledge, it’s a powerful thought that has always attracted me to the field.  Neuroscience is essentially one of the only fields of science that lacks a foundational principle.  In other words, we know so little about the brain.  We know far more about galaxies light years away!

What do you do?

My research focuses on DNA damage and repair in adult neurons.  Every cell of your body, except neurons, can copy its genome in case the original suffers damage.  Because neurons don’t divide, your neurons are stuck with the same copy of DNA your entire life!  My work aims to better understand how neurons handle DNA damage, and how a lifetime of this damage can accumulate and manifest as a disease like depression, schizophrenia, and especially age-related diseases like Alzheimer’s or Parkinson’s disease.

What are your data, and how do you obtain them?

To test DNA-instability in neurons, we use genetic engineering tools like CRISPR/Cas9 to modify genes involved in DNA damage repair.  I then measure structural changes in individual neurons.  Working with brain tissue, I can label proteins of interest using fluorescent dyes, and visualize them in 3D space using a confocal microscope, followed by 3D reconstruction of individual neurons.  Confocal microscopes emit a high-powered laser that shows nanometer structures…it’s like peeking inside a single neuron!

(Left) Flourescent 3D image of a single labeled neuron from the striatum of the mouse brain, captured using a Nikon Confocal Laser Scanning Microscope. (Right) Image is magnified and partially reconstructed using commercial software. Reconstructions permit detailed analyses of neuronal morphology.

How does your research contribute to the betterment of society?

The world is rapidly aging, and as of date no disease modifying therapeutics exist to combat neurodegenerative diseases.   Unlike other diseases, patients with neurodegeneration never recover and family members are exhausted from caring for them.  This means no one advocates for these patients or these diseases and often funding lags behind other fields like cancer research.  This has led many experts to sound the alarm and warn of a coming neurodegenerative epidemic [1].  My research suggests DNA-instability underlies neurodegeneration, and I hope the technology we’re developing can expedite drug discovery for these diseases and thereby lessen the burden families and society will face.

What advice do you have for aspiring scientists?

For anyone considering a career in science, particularly entering into a life science PhD program, you should know it will be the most exciting, rewarding, stressful and frightful time of your life, so you should be ok with all those emotions!  I recommend thinking about potential career paths after graduate school – go perform the self-assessment [2] at the link below (it’s designed specifically for life science graduate students).  Secondly, I would join a research lab ASAP.  Cold call professors at local institutions and tell them your plans.  Many undergraduate professors will be eager to take you in.

Ashley Ramsey, Staff Geologist for Geosyntec Consultants, Inc.

Professional Headshot.

What is your favorite part about being a scientist and how did you get interested in science in general?
My favorite part about being a scientist, why I chose science, and particularly why I decided to be an environmental consultant, is that the field is constantly changing, and there is always something new to learn, discover, or develop. Through my obtaining my undergraduate geology degree at Baylor University and my masters geology degree at The University of Tennessee, I was never sure what career path to take, but I knew that I liked to learn and do so at a very quick pace. Since beginning my consulting career just over one year ago, I have had the opportunity to study a multitude of contaminant impacts and remediation techniques for groundwater, porewater, soil, and sediment. Not only this, but every day I am fortunate to collaborate with scientists across the United States on a daily basis.

Step 1, wear proper PPE😊 Work can be a bit messy sometimes, but that’s half of the fun, right?!

In laymen’s terms, what do you do?
As a consultant at Geosyntec I conduct environmental contaminant investigations and remediations concerning chlorinated solvents, petroleum, metals, pesticides, and/or emerging contaminants. These contaminants are sourced from many historic and modern day industrial activities like dry cleaning and petroleum storage and sales among many others. My work over the last year and a half has been on sites located across state of Florida and have involved in soil, sediment, porewater and groundwater monitoring and sampling; contractor oversight; permitting; and the development and execution of proposals, remedial designs, and reports.

How does your work contribute to the betterment of society in general?
My work provides knowledge to clients and the public about the state of their environment and what steps we can actively take to better it. As environmental consultants we conduct investigations to ensure environmental contaminants are not migrating away from their source and that concentrations are not increasing. This work is extremely important as it ensures no harm is coming to the members of our community from the investigated contaminants as they go about their day to day lives.

What advice would you give to young aspiring scientists?
Keep at it! Sometimes you will have no idea which path to take and may become overwhelmed by those around you who already have their path determined. Take on a new project, study a new field, take that random class or field trip. By exploring every possible avenue, you will find your niche.

Ian Forsythe, Invertebrate Paleontologist and Undergraduate Researcher

I study ways we can tell species apart based on their morphology (the structure and shapes of their hard parts).  For my research, I use the fossils of brachiopods (marine animals that resemble clams) from the Upper Ordovician period (around 450 million years ago). I collect the majority of my data from fossils in museum collections but collect fossils in the field when I can’t find what I need in an existing collection. While the applications of my research may not be readily apparent it is actually applicable to a variety of things.

 Species are the fundamental unit we use to classify organisms and being able to tell them apart is an important skill. Being able to identify species based on morphology is a necessary step in many studies of evolutionary processes, climate change, ecology, and patterns of biodiversity (the numbers of species present on the Earth through time). This is even true for biologists studying modern animals! While modern biologists define species as members of a population that can actually or potentially interbreed in nature it isn’t reasonable or even possible to conduct breeding experiments for every animal on Earth. Therefore, from a practical standpoint morphology is the best way to identify species whether you study fossils or living organisms.

When I was five, I started collecting marine fossils from rocks near my home. The fact that where I lived used to be under the sea was amazing to me. Although I had an interest in science at a very young age, I didn’t consider it as a career until much later. It was a book I read my freshman year of college (Wonderful Life by Stephen J. Gould) that inspired me to pursue paleontology professionally. It is a story about the bizarre creatures that lived in the sea over 500 million years ago and the scientific struggle to understand them. My experience with science has been fascinating and rewarding in more ways than I can describe, but I have to say that my favorite thing about being a scientist is learning new and exciting things every day.

If I were to give one piece of advice to aspiring scientists, it would be that it is never too late to pursue a career in science. All kinds of people from all kinds of backgrounds become scientists and many of them start out pursuing other things (I started college thinking I would be a writer). If you are getting ready to start college and unsure what degree you want to pursue, try taking some courses at a community college. There are so many fascinating fields in science it can be hard to know which one is right for you and community college is a wonderful place to get a feel for what you may want to pursue.

Carmi Milagros Thompson, Invertebrate Paleontologist

Fun in the sun at Haile Quarry – fossil collecting tools at hand.

I have always been interested in science – when I was young, my mom would take us on the Metro to go visit all of the Smithsonian museums. My favorite was always the Natural History Museum (and I was lucky to go back as a research intern after I finished my undergraduate degree- but I digress). Growing up, I felt a lot of pressure to have a good career that paid well (doctor, engineer, lawyer, as the refrain goes)…so I was miserably going through a pre-med track, until I took a geology class…partially by accident, partially just to take all the sciences. I knew that I had to become a geologist from the first lab session where we scrambled down a hill to look at some Coastal Plain outcrop. Paleontology was also a mistake, but a happy one – a long story for another time! .

I think of my work as being similar to that of a librarian. Instead of books, I work with things that have been dead for (usually) millions of years. My job, as a collections manager, is (broadly) to organize and maintain holdings of fossil invertebrates (aforementioned dead things), so that people who are asking all kinds of questions about past life on Earth can quickly and easily access material. In addition to that, I supervise a rotating cast of interns and volunteers. When I’m lucky, I get to do field work (looking at fossils in the wild) with the rest of our research group – usually in Florida, but sometimes all over the country. No two days are ever the same – there are long stretches of identification and reorganization, of course, but most weeks are packed with visitors, curation, and more.

Behind the scenes at the Natural Museum of Natural History

In my “free time,” I guest contribute to the Neogene Atlas of Ancient Life (working on the scaphopods gap right now), coordinate and participate in outreach events at the museum and around the state, manage affairs for the Florida Paleontological Society as the secretary, maintain the invert paleontology collection website, and work with the Paleontological Society Diversity and Inclusion Committee. I am also working on a few personal research projects: a virtual collection tour (release date early fall), systematics and paleoecology of fossil cephalopods from Florida, and paleoecology of offshore molluscan fauna from the mid-Atlantic United States in sediment cores collected for beach nourishment. 

I was once described as “active on Twitter,” so I’ll plug that too  (see link at end of article) – my goal there is to promote our museum specimens and highlight different activities in which I participate – say hi if you’d like! 

ADVICE (as a young person who gets a lot of advice – here’s a brief summary!)

Digging for oysters in the Florida Panhandle.

In terms of paleontology specific advice, keep your options as open as possible – paleontology is certainly a competitive field, but there are many ways to pursue it as a career (there is a good blog post here about it!). For general career advice, find your support team – mentors, classmates, other professionals…people who will cheer you on throughout your successes and support you when things aren’t so great. And, this is such a geologist thing to say, but keep it all in perspective – there are going to be really tough times and problems that seem like they are impossible in the moment (everyone struggles), but think of the long term. Things usually have a way of working themselves out, often in surprising ways. I find that success usually outweighs the many, often-invisible failures along the way.

Laura Speir, Paleoclimatologist

Laura Speir sitting in front of the instrument they use to analyze oxygen isotope ratios to understand climatic changes. Much of the work Laura does involves lab work as opposed to field work.

I study changes in past climate using fossils, focusing on climate 500-450 million years ago during an event called the Great Ordovician Biodiversification Event (or GOBE). The GOBE represents one of the largest and longest diversification events (where a huge number of new species evolved) in earth history. Many scientists, including myself, are trying to understand the role of climate on the GOBE. Leading into the GOBE, the earth was very warm, warmer than we would expect for animal life. During the peak of the GOBE, the oceans appear to have cooled to temperatures slightly warmer than what we see today.

For my research, I use microfossils known as conodonts. Conodonts are extinct animals that are similar to hagfish or lampreys. We usually don’t find the whole conodont animal, but rather their “teeth” are left behind. We use these “teeth” (known as conodont elements) as a proxy for understanding climate. This is because conodont elements preserve the changes in different oxygen elements (known as isotopes) within the ocean. The ratio between these oxygen isotopes (16O and 18O) can be measured and a temperature can be calculated. While some scientists will collect rocks that contain conodont elements themselves, I receive conodont elements from paleontologists who have done previous research using conodont elements.

So, why do scientists like myself study past climates? By studying climates in the distant past, we can better understand how our climate is changing now. Scientists who create climate models use past climate data to better their models and studying periods of time when the earth was vastly different than our own allows climate modelers to test the limits of their models.

Outside of research, I am a teaching assistant for the University of Missouri geology field camp. Many geology programs require a field course where the students spend some amount of time learning how to recognize different rocks within the field and how to place them onto a map. The University of Missouri takes students to the Wind River Basin near Lander, Wyoming to learn these skills, as well as a fantastic trip to the Yellowstone and Grand Teton National Parks. I was a student at this field camp myself back in 2016 and have been a teaching assistant there for the past two field seasons. The geology in this region is absolutely stunning and makes a wonderful field area for our students to learn stratigraphy and mapping. Geology gave me the opportunity to travel across the country (and to Spain and Portugal, as well).

One of my favorite things about being a scientist is having the opportunity to share what I do with a variety of people. I participate in many outreach events and tell the general public about paleontology. Many students are not exposed to geology or paleontology in school, but these outreach events allow students (and their families) to learn about the earth. While I was never exposed to outreach events such as the ones I participate in now, I was fortunate enough to take earth science courses during high school, as well as an introductory geology course at my local community college. Looking back, however, I was always interested in the processes that governed the earth, from rocks to meteorology to biology.

There is no one true path to entering a science field. Many of us started out wanting to enter different field (I myself originally wanted to go into film). Community college is a great place to start your journey, particularly if you are unsure what field you want to major in. If you are in college, take a variety of courses. If you find a science course that you enjoy, don’t be afraid to take similar classes. Find a field that you enjoy doing and pursue it.

On being non-binary in science

Recently, I came out as non-binary. I do not identify as male or female, but somewhere between the two. While there are a growing number of scientists who identify as LGBTQIA+, finding other scientists in your field can be quite difficult. However, there is a growing effort for science organizations to provide opportunities for LGBTQIA+ people and many organizations are adjusting their policies to protect against gender identity discrimination. This is a huge step forward, as some states and cities do not provide such protections. Some scholarships and awards that I had previously applied for or considered applying for are women-specific, as women are, generally, poorly represented in science. However, some of the organizations I have talked to are willing to open their applications for non-binary/agender/genderfluid people, as they are also poorly represented in science.

As a grad student, my peers are generally accepting of my gender identity. My professors (and most importantly, my advisor) have accepted my gender identity and have made every effort to adjust their language regarding my pronouns (they/them). The occasional slip up does happen (even by me!) and I do my best to correct people. My biggest worry is how my gender identity will affect my future career. Will the hiring committee be accepting or will they look the other way because I do not conform to their ideas of gender? As I continue my journey, my hope is to find more scientists like myself at different points in their careers and learn how they have overcome the obstacles they have faced.

What is your favorite part about being a scientist and how did you get interested in science in general?
I love trying to understand the paths that organisms took throughout evolutionary history, so I really like studying fossils in order to understand modern animals. I grew up loving dinosaurs as a kid and I guess I just never grew out of that phase, but I’ve always been interested in pretty much all animals- fossil and living. When I was an undergrad, an opportunity arose to participate in a short field course in Costa Rica about bat ecology. I brought it up to my parents and they didn’t say yes, but they didn’t say no either, so I applied and ultimately was able to travel to Costa Rica and spend three weeks in the rainforest studying bats. During my Master’s degree I started to merge my interest in bats with my interest in paleontology and ultimately ended up where I am now: studying bat paleontology and evolution.

In laymen’s terms, what do you do?
I study the evolution of mammals shortly after the extinction of the (non-avian) dinosaurs. My main focus is on the paleontology of bats and other small, insectivorous mammals- creatures like shrews and hedgehogs- during the first two intervals of time following that extinction: the Paleocene and Eocene epochs. Bats are a particularly interesting group to work with because they show up suddenly in the fossil record at the beginning of the Eocene epoch, about 56 million years ago, and they are almost instantly found worldwide. We have no idea where they came from or what their ancestors looked like.

How does your work contribute to the understanding of climate change, evolution, paleontology, or to the betterment of society in general?
Powered flight has only evolved four times in the history of life: in insects, pterosaurs (the flying reptiles that lived at the same time as the dinosaurs), birds, and bats. So evolving flight is really hard to do, but it unlocks a lot of opportunities for the animals that can do it. Unfortunately, we don’t know as much about how bats achieved flight as we do about how birds did. There’s no equivalent of Archaeopteryx for bats, so there is still debate as to the closest relative to bats. There are more species of bats than any other mammals except rodents, and bats do everything from pollinating tropical forests to controlling crop pests. The ability to fly clearly helped bats become some of the most successful mammals on the planet, but since we don’t know what they evolved from, we have no idea how they became such specialized creatures.

Teeth of a primitive bat my colleagues and I recently described named Anatolianycteris insularis, from the middle Eocene of Turkey. A-C are a lower premolar viewed from the top, tongue side, and cheek side, respectively, and D is a lower molar viewed from the top.

What data do you use use for your research?
Since the earliest bats known from the Eocene look pretty much like modern bats, a lot of my research has focused on little insectivorous animals from the Paleocene Epoch. A lot of mammals from that time period are known only from their teeth. This is less challenging than it sounds because mammal teeth are very diagnostic, sometimes even down to the species. In particular, I’m focusing on one group of insectivorous mammals known mostly from their teeth called nyctitheres. There has been some thought that they might be related to bats, but that has never really been tested explicitly. So I spend most of my time looking at tiny nyctithere and bat teeth under a microscope in order to conduct a thorough analysis of their relationships.

What advice would you give to young aspiring scientists?
Be curious about everything, even if it isn’t super closely related to the field you are interested in. I love going to talks about things like ecology and genetics, and I end up learning a lot that I can apply to my field. Or I learn things that help me understand what my fossil animals would have been like when they were alive, how they interacted with their environment, and how they evolved.

Also, get involved and don’t be afraid to ask questions. Most scientists I know really like what they study and they are happy to talk to students who are interested. When you get to college, reach out to professors and ask if you can get involved in doing research in their lab. But don’t feel bad if you don’t know something. No one can know everything about a particular field, no matter how long you study it. So ask people if you don’t understand what they are talking about, or a phrase or concept that they used- there’s no shame in that.

Mattie Jensen, Microbiologist & Technical Manager

I am a Scientist.

It may be a little cliché, but like all scientists I know, I was always interested in science. It was one of those subjects in school that came naturally to me. By the time I graduated high school, I had taken all of the advanced science courses offered by my school, plus two college-level courses. You would think someone this driven by science would immediately jump into a science degree in college, right? Nope.

I attended college for graphic design. After a semester, I changed my major to photography. A couple semesters later, I changed my major to psychology – and that is where my real journey began. Eight years of hard work, studying all night while working multiple jobs to support myself through school, and I finally had my degree – my major was psychology, my minor was biology. I focused on a neuroscience approach to addictions and wanted to be a drug and alcohol therapist.

Along the way, I found myself working as an office manager for a microbiology laboratory. The work they did fascinated me, as I had many happy flashbacks to the courses I took in high school and college. As I worked my way through school, I also worked my way into the laboratory. Upon graduation, I jumped into a rigorous training program to become a microbiologist, led by an incredible mycologist and a snarky clinical bacteriologist. Seven years later – I run an environmental microbiology lab outside of Chicago for this company.

Long story short – plans change, but who you are at your core and what truly excites you remains the same. Science was always a part of me. I was always the kid questioning everything, asking Why and How, solving problems logically and methodically, taking horrible notes that somehow made sense to only me. I was weird. I got made fun of a lot. And I’m still weird. But I made a career out of it, so I’m really not complaining.

What Do I Actually Do?

I am a microbiologist, specialized in the indoor air quality, water quality, and industrial hygiene worlds. I don’t analyze any human-based samples, but I am responsible for keeping a lot of people safe. From pharmaceutical production, to the mold growing under your kitchen sink, to the water grandpa Joe uses to take showers at his assisted living facility… we’re on it.

Our clients go out and take a variety of sample types, and we analyze them for any potential pathogens that may be present. We do old-school, bench-top, human-driven science. We aren’t relying on fancy machines to analyze things for us, and sure our reference materials may be a couple decades old, but what we do is tried and true.

Why is this important?

Bacteria and fungi are amazing and mind-blowingly smart. They’ve been a part of our world since it began. Outbreaks happen, yes, but the type of work an environmental microbiologist does is all about being proactive. If a pharmaceutical company is producing medicine in a contaminated environment, we stop it from reaching you. If grandpa Joe is being exposed to potentially pathogenic bacteria in his water, we catch it and help remediate it. And even though your house is spotless and you would eat off of your floors, we highly suggest you don’t because you have six different types of mold growing under your sink.

The environmental world of microbiology is full of unsung heroes. If you don’t work for the CDC, no one really knows what you do or really knows why it’s important. But that’s okay, we’re all a bunch of nerds and don’t want the spotlight anyway. I still want to get involved in local colleges and reach out to inspiring young scientists because this world is dying. What we do isn’t even really taught in schools anymore, as more and more schools focus on clinical laboratory sciences and molecular research using expensive machines. Not saying any of that is bad, learning more and more about the world around us is a huge part of science, right? But we’re already fighting an anti-science, anti-vaccine movement right now, let’s not also let the bacteria around us win and party with the re-emerging viruses.

Are you a Scientist, too?

If you, too, are a kind-of-weird person, always asking why and how, never leaving any problem unfinished, maybe you’re a scientist too. Even if you can’t make up your mind in what you want to do with your life but you kind of relate to Mr. Spock on a personal level, maybe you’re a scientist too. If you are interested in a scientific field, do tons of research before settling down! There’s more to microbiology than clinical laboratories. I’d be happy to connect with you and tell you more!
