I am an Associate Professor in the Department of Mathematics at UCSB.
Previously, I was an Instructor at Princeton University,
and before that, a Hedrick Assistant Professor at UCLA.
Here is my CV (last updated: August 2023).
My research is partially supported by the NSF grant DMS-2101458.
Seminar on Geometry and Arithmetic
Research Interests: Number Theory and Arithmetic Geometry.
More specifically: p-adic L-functions, Euler systems and Iwasawa theory.
