I am a mathematician primarily working in the areas of low dimensional topology, geometric analysis, and spectral theory. I am particularly fond of applying techniques from the areas of geometry and spectral theory to the study of problems in topology. Most of my research has focused on understanding the topology of hyperbolic 4-manifolds, higher order geometric flows, and the study of spectral properties of geometric operators, such as Dirac type operators and Schroedinger type operators, on noncompact Riemannian manifolds.
