Bio

My main interests are in fully nonlinear elliptic PDEs, particularly those of Monge-Ampère type. These equations arise in many contexts such as optimal transport, geometric optics, and irrotational fluid flow; currently my main focus is on regularity and partial regularity properties of solutions. I am also interested in numerics for Monge-Ampère type equations.
