Research interests: Probability, Analysis and Mathematical Physics on graphs, resistance spaces, and metric measure spaces, such as fractals.

Most recently I have been studying the scaling limits of discrete stochastic processes which are many-particle extensions of the (simple) random walk process, such as the exclusion process, sandpile models, and internal diffusion-limited aggregation, on weighted graphs. I also continue to study spectral aspects of Laplace or Schrödinger operators on self-similar spaces, with applications to PDEs, quantum mechanics, and statistical mechanics.

I rarely pick sides on the Yale-UConn rivalry or the Cornell-Colgate rivalry. I will, however, use math humor to defuse the rivalries.
