Research

I am an assistant professor at Rice University, working in algebraic geometry and arithmetic geometry. From 2022-2025, I was a JWY Research Instructor at Dartmouth College. From 2019-2022, I was an RTG Lovett Instructor at Rice University. See my research page for my papers and preprints.

I received my PhD in June 2019 from the University of Oregon, where my advisor was Nicolas Addington.
