Karol Koziol
I am an assistant professor in the Mathematics Department at Baruch College, City University of New York. I am interested in various aspects of the (local) Langlands Program, specifically representation theory of p-adic reductive groups, associated Hecke algebras, and Galois representations.
My research is partially supported by NSF grant DMS-2310225.
Previously, I was
• a postdoctoral assistant professor at The
University of Michigan, supervised by Stephen
DeBacker;
• a postdoctoral fellow at The
University of Alberta, working with Manish Patnaik;
• an NSF Postdoctoral Fellow at The University of
Toronto, with sponsor Florian Herzig;
• an EPDI Postdoctoral Fellow at the Institut des Hautes Études
Scientifiques and the Max Planck Institute
for Mathematics;
• a graduate student at Columbia University
under the supervision of Rachel Ollivier;
• an undergrad at NYU.
Here is a 2-adic version of
me.
