My research interests lie at the intersection of probability and combinatorics, with some motivations from statistical physics. I have done research on various stochastic processes that exhibit self-organized criticality, building a unifying theory for those processes. I have also worked on random walks in random environments that interact with the walker, where the uniform spanning forest makes a surprise appearance.
