Research Interests:

My research interest lies at the intersection of number theory and arithmetic geometry. On the one hand, on the number theory side, I work on local-global representation theory, automorphic forms, and classical modular forms ; on the other hand, I pursue various projects on elliptic curves over global and local fields on the arithmetic geometry side. Another part of my research focuses on exploring the connection between number theory and arithmetic geometry using L-functions and Galois representations, which broadly comes under the Langlands Program. Recently, I am also working on a few projects in computational number theory.
