Research

My research interests are mainly ergodic theory and dynamical systems, but they intersect areas in geometry and mathematical physics. Below is a list of my written work.

Expository

  1. Unique ergodicity without moduli spaces. A summary of a talk I delivered at Oberwolfach in April 2014. It summarizes some of my thoughts at the time concerning unique ergodicity of translation flows.
  2. Numerically Computing the Lyapunov Exponents of Matrix-Valued Cocycles. Short note I wrote in graduate school on computing the Lyapunov exponents of cocycles with computers. February, 2011.
