Portrait of Peter Dillery

Peter Dillery

Research assistant (from October 2025), Department of Mathematics, University of Bonn

Interests: local & global Langlands correspondence, representation theory, related aspects of algebraic geometry.

About

I will be a research assistant at Bonn starting October 2025, working with Jessica Fintzen. I study the local and global Langlands correspondence, with recent projects touching related aspects of algebraic geometry. I received my Ph.D. from the University of Michigan in 2022 (advisor: Tasho Kaletha). From Fall 2022 to Fall 2025 I was a Brin Postdoctoral Fellow at the University of Maryland, where I co-organized the UMD Number Theory and Representation Theory Seminar and taught for the DC Math Circle. I organized the workshop Geometric Approaches to the Local Langlands Program. I am currently on the job market.
