Topology, Low dimensional topology, In particular topology of 3 and 4-dimensional manifolds.
Overview of your research
My main sbject is topology of 3 and 4-manifolds. I classified certain elliptic surfaces and 4-dimensional Seifert fibered spaces, constructed exotic group actions on 4-manifolds based on gauge theory and Seiberg-Witten theory. Recently I investigate invariants of 3-manifolds originated from these theories.
