Assistant Professor


Research area: dynamical systems, complex dynamics, Teichmüller theory

My research is in dynamics and geometry, especially the dynamics of rational maps on the Riemann sphere, the corresponding moduli space, and its interplays with Kleinian groups, hyperbolic geometry, Teichmüller theory and Berkovich dynamics.
