Linus Hamann

I like arithmetic geometry, especially in and around the p-adic numbers. My current research is concerned with leveraging connections between the classical and geometric Langlands correspondences to say more about the cohomology of Shimura varieties and related spaces.

I am a Benjamin Pierce Fellow at Harvard. Last year I was a NSF Postdoc at Stanford working with Xinwen Zhu. I received my PhD from Princeton in 2023, advised by David Hansen and Chris Skinner.
