I like to joke that I study imaginary fish. People often remember that or, even better, ask what it means. Then, I get to tell them that I study theoretical ecology; I use mathematical tools to investigate how organisms interact with each other and with their environment. I am studying in the MIT Joint Program with the Woods Hole Oceanographic Institution, so my organisms of interest tend to be marine, but the only places they swim are in my computer, in equations, and, always, in my heart.
