In winter semester 22/23 I give the lecture "Darstellungstheorie assoziativer Algebren" (Wednesday 10-12, Friday 10-12). Please find more details below.
My project "Modelling classical types: Algebraic group actions via algebras with symmetries" is funded by DFG during the time period 02/2021 - 01/2024.
I am a member of Graduiertenkolleg 2240 (Heinrich-Heine Universität Düsseldorf and Bergischen Universität Wuppertal).
