RESEARCH: As a mathematical physicist, I work on conceptual and mathematical problems arising in quantum field theory. I am particularly interested in new approaches to the problem of rigorously constructing quantum field theory models. A novel line of research addresses this question via operator-algebraic deformations of quantum field theories, a topic also connected to non-commutative geometry and quantum field theory on non-commutative spaces.

A further interest are integrable models in quantum field theory and related structures, such as the Yang-Baxter equation, braid group representations and link invariants.

For more details about my research, you can have a look at my publications and talks.

TEACHING: I am not teaching in the spring term 2019. In autumn 2019/20, I will be teaching “Mathematical Foundations of Quantum Physics” (MA4014) and “Foundations I” (MA1005). Previous teaching can be found here.
