I am a member of the Spectral analysis group at the University of Paderborn, Germany. Recently I have been working a lot with discrete subgroups of Lie groups such as Anosov subgroups. I am especially interested in the geometry, the dynamical systems and the spectral theory on the associated locally homogeneous spaces, which often possess interesting pseudo-Riemannian structures. In another independent line of research, I study oscillatory integrals in symplectic geometry.
