Welcome to my webpage !
I am currently a postdoctoral fellow at the Max Planck Institute for Mathematics in Bonn.
Before I was doing my Phd in Paris under the direction of Jean-François Dat . Here are some subjects I am interested in :
Langlands program : local and global both arithmetic and geometric
Representations of finite and p-adic Lie groups : Deligne-Lusztig theory, modular aspects, type theory, ...
Hecke categories, geometric Satake, Bezrukavnikov equivalences, Soergel bimodules, character sheaves, ...
Categorical traces and categorification
Stacks of chtoucas : their geometry and their cohomology
