Wendell Ressler Professor of Mathematics
Research
My field is analytic number theory. I study automorphic forms (and automorphic integrals), Dirichlet series, and Hecke correspondence. I am especially interested in Hecke groups, rational period functions, binary quadratic forms and continued fractions.
