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