Research Interest

My research involves various geometric problems in mathematical physics, especially those concerning mirror symmetry. I am also interested in other problems in string theory, e.g. vertex operator algebras and supersymmetry. The following are some areas that I have done some work:

Applications of equivariant cohomology and localization techniques.

Moduli spaces of Riemann surfaces and Hodge integrals

Frobenius manifolds and topological field theory

Vertex algebras from geometric objects

Study of singular varieties by super differential geometry

Homotopical mirror symmetry
