Background
I am a Lecturer in the School of Mathematics, Statistics and Physics.
I obtained my PhD from the University of Heidelberg. Before moving to Newcastle I held positions at The Ohio State University, the Max-Planck Institute of Mathematics in Bonn and the University of Bonn. I completed my Habilitation at the University of Bonn.
Research
Research interests: Representation theory and tensor categories. In particular:
- Deligne categories (certain families of universal tensor categories)
- Diagram algebras
- Stable representation theory of the symmetric group and some finite groups of Lie type
- Construction and classification of thick ideals and tensor ideals
- Representations of algebraic supergroups, in particular tensor product decompositions, the Duflo-Serganova cohomology functor and character/dimension formulae; applications to mathematical physics
- Homotopical methods
- Representations of quantum groups at roots of unity, their super versions and possible applications to quantum knot invariants.
- Tilting modules for quantum groups and algebraic groups
