Robert Cass


I am a fourth-year graduate student in the Department of Mathematics at Harvard University. I expect to graduate in 2021. My advisor is Mark Kisin.

My research interests include the Langlands program and related topics in algebraic geometry and representation theory.

I completed my B.S. in mathematics at the University of Kentucky in 2016.


Central elements in affine mod p Hecke algebras via perverse F_p-sheaves, Preprint, 2020.

Perverse F_p-sheaves on the affine Grassmannian, Preprint, 2019.

Here are the arXiv versions of my papers.
