I am an Associate Professor (Docent) at Chalmers University of Technology. I have previously worked at Örebro University (senior lecturer), the University of Copenhagen (postdoc), the Institute for Advanced Study in Princeton (postdoc) and Uppsala University (PhD student).

My research interests are in (analytic) number theory and related fields. I'm particularly interested in (zeros of) L-functions and zeta functions, the geometry of numbers and automorphic forms and functions.

I organize, together with Christian Johansson, the Seminar in Algebraic Geometry and Number Theory at Chalmers and the University of Gothenburg.
