These days I am studying microlocal sheaf theory and its interactions with symplectic geometry, cluster algebra, mirror symmetry, etc.

In the past I've studied moduli of sheaves on singular plane curves, curve counting on surfaces, categorified knot invariants, rational Cherednik algebras, and equidistribution questions.
