Research Area:

Symplectic topology/geometry

For the past few years, I have been working in the area of symplectic topology. Among my current research interests in this area are the following topics: the Flux Conjecture (recently proved by Ono), Floer homology, Novikov homology, and applications of Floer homology to the topology of symplectomorphism groups.
