**Research Interest:**

Smooth/symplectic topology in dimension four, symplectic topology in dimension six.

The Seiberg-Witten invariants of 4-manifolds and the count of J-holomorphic curves in 6-manifolds are the basic tools to get information about these structures.

Research interest expands to the related topics such as contact topology, surface bundles and mapping class groups.
