10th December 2018 – Katherine O’Reilly, University of Notre Dame and National Sea Grant College Program

Katherine O'ReillyI’m Katherine (AKA Katie AKA @DrKatfish), and I’m a Ph.D. candidate studying aquatic ecology at the University of Notre Dame and currently a National Oceanic and Atmospheric Administration (NOAA) Sea Grant Knauss Marine Policy Fellow in Washington, D.C., USA.

My research (in three words): fish, freshwater, and food webs. My research (in slightly more than three words): I look at how fish connect aquatic habitats in the North American Great Lakes. I use a variety of techniques such as stable isotope analysis and otolith chemistry to understand what kinds of habitats fishes use and when they are using them. Understanding freshwater ecosystems such as lakes and rivers, the animals that live there, and effects of humans is incredibly important in a world where freshwater is increasingly at a premium. We’ll be diving into a lot more on this topic during my week on BioTweeps!

Besides catching fish and hanging out on boats around the Great Lakes, you can find me this year in the halls of NOAA HQ as I complete my fellowship with NOAA’s National Sea Grant College program. I serve as Sea Grant’s Science Communications Specialist, which has been an amazing opportunity for me to get experience in doing #scicomm professionally. No matter where my future career path takes me after finishing up my Ph.D. (whether academia, government, or something else), the skills I’m learning during my fellowship year are going to serve me well.

Speaking of #scicomm, I’m so excited to be hosting BioTweeps during the best time of the year: #25DaysofFishmas! What is #25DaysofFishmas, you may ask? For the past two years, I’ve been sharing fish facts each day during December (along with terrible, terrible puns). It’s been an awesome way to connect people from all backgrounds, spread fishy holiday cheer, and maybe even teach people a little about science. While my #25DaysofFishmas started out focusing on Great Lakes fish species, the idea has caught on and now others are sharing fishes from around the world. I can’t wait to introduce BioTweeps to all the fishy fun this year!
