I'm a Professor of Mathematics (Algebra) at the University of Kaiserslautern-Landau (RPTU), member of the Algebra, Geometry and Computer Algebra group. My main research area is representation theory. I like interactions with algebraic geometry, category theory, combinatorics, and computer algebra—more generally also with computer science and physics. Some specific topics I am interested in are:

- Birational geometry and representation theory of symplectic singularities
- Representation theory of finite-dimensional algebras
- Anything Lie theoretic
- Tensor categories and categorification
- Algorithmic and constructive techniques

## News and schedule

### 2024

In the summer term 2024 I will be teaching *Character Theory of Finite Groups* and *Geometry of Schemes*. Moreover, I will supervise an undergraduate seminar on reflection groups (see OLAT for more information).
