My research is in Representation Theory, the focus being on the interaction of representation theory with geometry and combinatorics. Here are some key words: representation theory of algebraic groups, semisimple Lie algebras, Kac-Moody groups, quantum groups, ... , geometric constructions of representations, geometry of flag varieties and Schubert varieties, spherical varieties, building theory, associated combinatorial tools like Young tableaux, crystals, path model, galleries in a building etc.

Some more information about representation theory can be found for example on the web-page of the DFG priority program SPP 1388

Some (pre-) publications can be found here
