Research

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

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