I'm an algebraic geometer with broad geometric interests.

Lately I am studying microlocal sheaf theory, with a view towards its applications in contact geometry on the one hand and towards the moduli spaces which arise on the other.

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.

I am teaching Math 54 this semester.

I'm organizing the Berkeley-Tokyo winter school, Feb 8 — Feb 19.
