I am a postdoc at ETH Zurich working in algebraic geometry. My mentor is Rahul Pandharipande. Before joining ETH Zurich, I did my Ph.D. at UCSD under supervision of Dragos Oprea. Here is my CV.

I work in algebraic geometry with a focus on moduli spaces of sheaf-theoretic objects (e.g. stable sheaves, quotients, framed sheaves, quiver representations). Specifically, I study enumerative properties of these moduli spaces by means of partition functions, wall-crossing formulas, geometric representation theory.
