Rachel Roday, Graduate Student and Marine Scientist

My favorite activities are ones that help me connect to nature, such as SCUBA diving, kayaking, and painting landscapes. Even as a child, I spent all of my free time at the beach or obsessing over turtles, so it was no surprise when I decided to pursue marine science as a profession. I obtained my Bachelors of Science in marine science and biological sciences from the University of Delaware where I conducted research on shark respiration and zooplankton behavior. I also completed an internship at Mote Marine Laboratories in Sarasota, Florida examining red tide toxins from Florida beaches.

Currently, I am a graduate student at the University of Texas at Austin Marine Science Institute. Though I have yet to begin my thesis, my research will focus on understanding the role of per- and polyfluoroalkyl substances (PFAS) in marine fishes. PFAS are a group of approximately 4500 manmade chemicals that are water, heat, and oil resistant. They have been found in non-stick pans, fire-fighting foams, stain resistant carpets, and many other common use items and are known carcinogens in humans. Little is known about the impact of these chemicals on marine fishes, so I hope to fill some of this knowledge gap by determining the toxicity of lesser known PFAS compounds and how they might be transferred from parent to offspring. As a scientist, I aim to understand the extent of human impact on biology within the marine ecosystem. In the future, I hope to influence the regulation, product development, and disposal techniques of manmade chemicals such as PFAS, insecticides, sunscreens, and pharmaceuticals in order to protect the environment and ultimately, us humans.

It took me four years of undergraduate classes, several internships, and two wildly different research projects to figure out the specific area that I wanted to focus on in graduate school. In other words, I got really good at figuring out what I didn’t want to pursue. This would be my greatest piece of advice to someone looking to find their way in science or any profession: try out lots of things, as many as you can! Not only does a range in experience bring about a unique perspective, but you never know what one door might open for you later on down the road.

I also suggest that people learn about the science that interests them in their backyard or community. As a Long Island native, this was easy for me because growing up, I was surrounded by beaches. But even learning about the local plant life or stargazing at night can help curate your specific scientific interests. I believe that having a personal and maybe even emotional relationship with nature and science can instill passion that propels you through all of the more tedious and challenging parts of life. Overall, even if science is just a hobby and not a career end-goal, I think it’s important to find ways to make it accessible at home and never be afraid to ask questions!
