Research Projects and News

I am broadly interested in representation theory, number theory, algebraic geometry and mathematical physics. In particular, I study vertex algebras, conformal field theory, automorphic forms, infinite-dimensional Lie algebras and their connections. Here is a popular science summary of some of my recent work.

Together with Claudia Alfes I organised a workshop on Modular Forms and Representation Theory in 2022.

Funded research projects:

• Principal investigator: SFB 1624 Higher Structures, Moduli Spaces and Integrability
• Principal investigator: Emmy Noether Programme Vertex Algebras Associated with 2- and 4-dimensional Conformal Field Theories
• Key researcher: cluster of excellence Quantum Universe

Ph.D. students:

• Hannes Knötzele
