About me

I am an Assistant (postdoc) at the Mathematical Institute of the University of Bonn, with Tasho Kaletha.

Previously, I was a postdoc at the Mathematical Insitute at the University of Oxford, with James Newton. I finished my PhD at the Department of Mathematics at the University of Michigan, Ann Arbor in 2022, with Kartik Prasanna.

I am interested in topics related to automorphic forms, arithmetic, and the Langlands Program.
