## Research

I am an assistant professor in the math department at Penn State University. Previously I was a postdoc at UIC, and I completed my Ph.D. under Joe Harris at Harvard. My research focuses on algebraic geometry. In particular, I focus on Hilbert schemes of points, moduli of vector bundles, and various interpolation-type problems that arise in algebraic geometry.
