Profile
Abhishek Saha is a Lecturer in Number Theory at Queen Mary University of London, School of Mathematical Sciences. As of 2018-2019, Saha is also the Deputy Director of Research in the School of Mathematical Sciences at Queen Mary.
Prior to joining Queen Mary, he was a Lecturer in Number Theory at the University of Bristol. He obtained his PhD from the California Institute of Technology in 2009.
Saha's research interests include number theory and automorphic forms, with close connections to spectral theory, representation theory, and geometry. 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.
