Research

My research interests are in the fields of hyperbolic geometry, low-dimensional topology, and Teichmüller theory. I mostly think about surfaces. A lot of my work has been about counting curves/geodesics on surfaces in various settings, often using geodesic currents as a main tool. I also like to think about (Euclidean and hyperbolic) billiards and their associated unfoldings. 

All my papers are on the ArXiv
