Research Interests

My research is centered on the study of complex manifolds and Lie groups of holomorphic automorphisms acting on them. This work has primarily involved homogeneous complex manifolds—-their classification, computing numerical invariants, and establishing various vanishing theorems for their cohomology. I have also been interested in analyzing the quotients of complex manifolds by the actions of Lie groups.

My most recent work determines bounds for the anticanonical bundle and the dimension of the holomorphic automorphism group of a homogeneous compact complex manifold.
