Overview

Research area: Differential Geometry, Partial Differential Equations, Calculus of Variations

My research is in the field of geometric analysis—the study of geometric partial differential equations and variational problems motivated by questions in geometry, topology, and mathematical physics. My work combines local analytical tools and global variational methods to study solutions of partial differential equations related to minimal submanifolds, harmonic maps, gauge theory, and geometric measure theory, with applications to the study of scalar curvature and spectral theory, among other areas.
