You can probably tell that my research interests have varied quite a bit. My Ph.D. was a mix of representation theory and probability used to analyze random walks on algebraic structures. More recently, I’ve been fascinated by mathematical questions arising from problems in the social sciences. I’ve been carving out a niche solving problems in geometric and topological combinatorics (e.g., triangulations of polytopes and fixed point theorems) and using them to study problems of fair division in mathematical economics, and voting problems in game theory.
