Analytic number theory; automorphic forms; and L-functions.
Jakob Streipel's research centers around using GL(2) spectral theory in order to study automorphic forms coming from or being somehow related to GL(2) objects. This includes studying holomorphic modular forms and GL(2) Maass forms and their L-functions, but also higher rank objects like GL(3)×GL(2) L-functions in the GL(2) spectral aspect. This tends to involve moments of the corresponding L-functions, often with twists in order to make for interesting applications.
