Between January-September 2023, I worked as a Wissenschaftlicher Mitarbeiter at the HHU Düsseldorf
at the Group Theory workgroup of
Prof. Benjamin Klopsch.
My new address is at Technische Universität Dresden.
I am a Privatdozent at the FU Berlin, Institüt für Mathematik. Here is my webpage at FU Berlin.
I am interested in simple groups of Lie type, finite and
locally finite groups and their automorphisms, linear algebraic
groups, profinite groups. Here is my CV and my Habilitation Thesis, which contains a summary of my research.
Previous terms, I taught the following courses at the FU Berlin:
on Profinite Groups.
on Group Theory
Mathematik für Physiker 2
on Simple Groups of Lie type.
Algebraic Groups and Finite Groups of Lie type.
I co-organized the conferences
Group Theory in Berlin 2019
Groups and Topological Groups, Berlin 2022
