Research Interest
Number theory and automorphic representations. More specifically, I am interested in the interaction of the following topics as predicted in the Langlands Program:
- Arithmetic of Shimura varieties, Rapoport-Zink spaces, affine Deligne-Lusztig varieties, etc.
- Automorphic representations, Arthur-Selberg trace formulas and endoscopy
- Representation theory of real and p-adic groups.
Recent teaching
- Spring 2023. Representations of p-adic groups.
- Spring 2022. Topic course on Shimura varieties.
- Summer 2021. Mini course at BICMR: Counting points on Shimura varieties. (website), updated notes
- Spring 2021, Math 621: Algebraic Number Theory II. updated notes
