I work on representation theory, with a focus on p-adic groups, character theory, wavefront sets, Hecke algebras, and the Langlands program.

I am co-organising the conference Wavefront Sets in Number Theory and Representation Theory, which will take place at the Institute for Mathematical Sciences, National University of Singapore, in September 2027. Information will be updated here.
