I’m a member of the Algebra, Geometry and Computeralgebra group at the University of Kaiserslautern. My main research focus lies in algebraic geometry, representation theory, and (higher) category theory—mostly in the context of algebraic Lie theory. I also develop computer algebraic methods. Specific topics I am interested in are:

- Symplectic algebraic geometry (symplectic singularities, Poisson deformations, symplectic duality, minimal model program; symplectic reflection algebras, rational Cherednik algebras, Calogero–Moser spaces)
- Coxeter groups, Kazhdan–Lusztig theory, Hecke algebras
- Complex reflection groups, cyclotomic Hecke algebras
- Highest weight categories, cellular algebras
- Soergel bimodules
- Tensor categories
- Generic representation theory
- Computer algebra
