My research is in representation theory. Representation theory is an ubiquitous area of mathematics relevant to different subjects such as algebra (associative algebras, Lie theory, Langlands program), number theory (automorphic forms), harmonic analysis (Fournier analysis) and geometry (invariant theory).

The focus of my research is on the representation theory of finite dimensional algebras. In particular, I'm interested in cohomology theories, homological algebra, and connections of representation theory to other areas of mathematics.


NEW: Research school 'New trends in representation theory: the impact of cluster theory on representation theory', from 20-24 June 2017, University of Leicester. The research school is supported by the London Mathematical Society, the Clay Mathematical Institute, the Heilbronn Institute and the department of Mathematics at the University of Leicester.  For more information, click hereOrganizers: Karin Baur (Graz) and Sibylle Schroll (Leicester)
