RESEARCH:

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.


TEACHING: I will teach Linear Algebra II and Mathematical Foundations of Quantum Physics in the autumn term 2020/21. Details on on/offline teaching activities will be communicated in due course. Previous teaching can be found here.
