I am a postdoc working in representation theory of Lie algebras, quantum groups and generalized Weyl algebras. Since 05/2017 I am employed at the headquarters of Deutsche Telekom AG in Bonn, including regular research leaves.

From 09/2016 until 04/2017 I was a postdoc at the Institute of Algebra and Number Theory at the University of Stuttgart in the working group of Steffen Koenig.
I did my PhD in 07/2016 here in Bonn supported by BIGS, the IMPRS program of the Max Planck Institute for Mathematics, and by a Deutsche Telekom Stiftung scholarship. I was part of the Algebra and Representation Theory in Bonn working group, my advisor was Catharina Stroppel.


I study Generalized Weyl Algebras, in particular I am interested in
  • Primitive ideals
  • The center and commutative subalgebras
  • (Highest) weight modules
  • Categorification of (highest) weight modules
of Generalized Weyl Algebras, but also for simple Lie algebras, Quantum groups etc.

Furthermore, I am interested in diagram algebras and related algebras, like the affine nilTemperley-Lieb algebra or the plactic algebra, for which I look at
  • Graphical representations via particle configurations
  • Bases
  • Relationship to affine cellular algebras
  • Description of the center.
