About me: I am an associate professor in the Department of Mathematics at Michigan State University, where I have worked since 2016.
My research is partially supported by NSF grant DMS-2154408. In the past, my work has been partially supported by the Simons Foundation.
Research interests: I am broadly interested in algebra, number theory, and arithmetic geometry. Much of my current research deals with the arithmetic of algebraic groups over higher-dimensional fields and Galois cohomology. In the past, I have also worked on the analysis of abstract homomorphisms of algebraic groups over general fields and rings. Further details can be found in this survey paper.
Videos of my past talks at the Banff International Research Station, the Institute for Advanced Study, and the online seminar on Quadratic Forms, Linear Algebraic Groups, and Beyond can found here, here, here, here, and here.
Recent Events:
In Fall 2025, I was the lead organizer of the BIRS workshop Arithmetic Geometry and Algebraic Groups (25w5323). The final report for the workshop can be found here.
In Spring 2023, I was a co-organizer of the conference Arithmetic Geometry and Algebraic Groups that was held at the University of Virginia.
Current teaching: In Spring 2026, I am teaching MTH 132: Calculus I.
