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

Starting Fall 2025, I will be an assistant professor at Rice University.

Curriculum Vitae

Here is my CV.

Teaching

For the Spring 2025 quarter, I am teaching Math 19: Introduction to Set Theory. See my teaching page for more information, as well as a list of the courses I've taught in the past.
