Research
My research is centered around leveraging curvature in differential geometry to understand fundamental concepts and problems in algebraic geometry, complex geometry, and topology. I am particularly fond of the Bochner technique, and more specifically, the Schwarz lemma for holomorphic maps between Hermitian manifolds.
