Profile

Research Interests:
Abhishek Saha's research interests include number theory, automorphic forms, classical and higher rank modular forms, representations of p-adic groups, automorphic representations, and L-functions. Broadly speaking, his current research has two main directions. One direction deals with the analytic properties of automorphic forms and their associated L-functions. The other direction investigates the arithmetic and algebraic properties of cohomological automorphic representations, especially those coming from classical or Siegel modular forms. Thus, Saha straddles a uniquely broad research portfolio, with expertise in the areas of modular forms, algebraic number theory, modern representation theoretic methods, as well as techniques of analytic number theory.
