His contributions include works on p-adic L functions and real-analytic automorphic forms. His work on p-adic L-functions, later recognised as an aspect of Iwasawa theory, was jointly with Leopoldt. He extended the concept of metaplectic group, in a way significant for arithmetic applications.
This opened a field for later research on associated Dirichlet series and automorphic forms, and was a major step in the solution of Kummer"s conjecture.
