### About me

I'm currently an NSF postdoctoral fellow at MIT. Starting Fall 2019, I will be a Benjamin Peirce and NSF postdoctoral fellow at Harvard University. I received my PhD in 2018 from Brown University under the supervision of Dan Abramovich.

### Curriculum Vitae

### Research

I'm mainly interested in algebraic geometry -- specifically moduli spaces and birational geometry with connections to enumerative geometry, combinatorics and geometric representation theory.

One of my current focuses is on compactifying moduli spaces of surfaces using ideas from the minimal model program. More specifically, I'm studying surfaces that admit a fibration to a smooth curve. Using the theory of twisted stable maps to Deligne-Mumford stacks, one can construct natural degenerations of such fibered surfaces and apply them to compactify moduli spaces by KSBA stable pairs.

My other current focus is on the combinatorial and enumerative geometry of moduli spaces of sheaves, and particularly Hilbert schemes of points. I'm interested in the rich interplay between partition combinatorics and the geometry of Hilbert schemes of points on smooth surfaces and surface orbifolds. I'm also interested in the structure of Hilbert schemes of points on singular curves, espcially generalizing results about planar curves to larger embedding dimension and connections with curve counting on threefolds. I'd also like to understand tropicalizations of these moduli spaces.
