About Me
I am an assistant professor at Notre Dame. My work lies at the juncture of geometry/topology, geometric group theory, and complex algebraic geometry. I study the connections between mapping class groups (including braid groups), some closely-related topological spaces (surface bundles and configuration spaces), and moduli spaces of Riemann surfaces and Abelian differentials.
I received my Ph.D from the University of Chicago in June 2017, where I was a student of Benson Farb. Prior to Notre Dame, I was a Ritt Assistant Professor at Columbia University. From 2017-2020 I was supported by an NSF postdoctoral fellowship, at Harvard with Joe Harris and at Columbia with Walter Neumann.
I am supported in part by NSF CAREER grant no. DMS-2338485.
In summer 2025, I am organizing a thematic program at the Center for Mathematics at Notre Dame, on the theme of "Discrete groups in topology and algebraic geometry". Here is the program website.
Along with Riverbend Community Math Center, I am organizing a Math Circles Institute to run at Notre Dame (July 14-19 2025). Here is the program website.
