From 1 September 2021, I will be working at Erlangen University.



My research focuses on applications of operator algebras to 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 research field of mine are unitary solutions of the Yang-Baxter equation, in particular their classification by subfactor methods and braid group characters and their application to integrable quantum field theories.

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

PhD position available (at Erlangen, from autumn 2021)

TEACHING: In autumn 2021/22 I am teaching Spectral Theory and a seminar on Braids and Knots. Previous teaching can be found here.
