## About Me

I am an Omidyar Fellow at the interdisciplinary Santa Fe Institute; my "home discipline" is (theoretical) computer science. My research lies primarily at the intersection of theoretical computer science and mathematics—particularly algebraic geometry, representation theory, and group theory—but I am starting to branch out into more general complex systems and, thereby, more worldly pursuits such as biology, energy, and the environment (which I've been interested in for most of my career).

Prior to coming to the Santa Fe Institute, I was a postdoc in the University of Toronto CS Theory Group, and prior to that I got my Ph.D. at the University of Chicago.
