I'm an RTG postdoc at the University of Oregon, working with Nick Proudfoot.
I'll be on the job market for postdocs and tenure track in fall 2025.
I'm interested in the intersection of algebraic geometry and combinatorics, especially in the geometry of hyperplane arrangements and matroid theory. My advisor was Botong Wang.
