My research interests are centered around various aspects of Mathematical Physics. In particular, I have been working on two dimensional exactly solvable quantum field theories, their mathematical structure and their applications. I am member of the Collaborative Research Center SFB|TR12 "Symmetries and Universality in Mesoscopic Systems", contributing to the subprojects "Topological Insulators with Interactions" and "Symmetries and structure of 2D conformal superspace sigma-models". I am also member of the newly established Center of Excellence "Quantum Matter and Materials" (QM2).

Most of our group is busy with one or more of the following subjects...

Disordered systems and topological phases of strongly correlated systems:

Constructive aspects of quantum field theory and string theory:

Representation theory:
