Research Interest

I am currently interested in compact holomorphic symplectic Kähler manifolds and algebro-geometric structures on them. I also have an interest for moduli of semi-stable sheaves, birational geometry of higher dimensional varieties, and geometric invariant theory as related topics to holomorphic symplectic geometry.
