My research focuses on fully nonlinear equations arising from geometric problems and related geometric flow problems. I study existence, uniqueness, regularity, and qualitative properties of solutions. I am especially interested in the interaction between these two fields, that is, using fully nonlinear equations to study curvature flows or using flow methods to solve classical problems in PDE.
