Analysis of PDE

I'm interested in nonlinear elliptic problems, in particular, variational equations and topics related to existence and regularity of solutions.

Hodge theory & Complex Algebraic Geometry

I'm interested in Algebraic cyles and its connections. Topics include cycle class maps, Hodge-D and Hodge conjectures, higher Chow groups, real regulators and related topics.
