General information

I am an Assistant Professor of Mathematics at Stanford University.

My research is in topology, especially low-dimensional topology, and often uses representation theory. I am especially interested in moduli spaces, broadly defined.

I am an organizer of the Topology Seminar. My CV is available. My office is 383Y in Sloan Hall (Building 380, on the Main Quad).
