Mathematical interests: My primary interest is in non-Archimedean geometry and its interactions with the tropical and birational geometry of algebraic varieties. I also like to think asymptotics in algebraic varieties over finite fields, and about operads, especially in the context of algebraic geometry.
Education: I received my Ph.D. from Yale University, under the direction of Mikhail Kapranov, and I did my undergraduate work at the University of California, Berkeley.
Teaching: This Spring 2019 semester, I'm teaching Calculus II (MAC2312, Section 0019).
