About me

I am a tenure-track assistant professor at University of Maryland, College Park.

From 2019 to 2023, I was a Benjamin Peirce and NSF postdoctoral fellow at Harvard University. I spent the 2018-2019 academic year as an NSF postdoctoral fellow at MIT. 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 number theory, enumerative geometry, combinatorics and geometric representation theory.

Personal

A long time ago, I was studying math at Caltech and spending my time in Ricketts House.

This is a picture of me and my beautiful wife and our dog Grizzly.

I also like playing music. Here are some very rough performances.
