I am a Privatdozent at the FU Berlin Institut für Mathematik
and also I work for University of Palermo at a research project.
I am the subject editor of the areas of group theory, topological and Lie groups in zbMATH Open.
Last year I worked at Technische Universität Dresden as a Vertretungsprofessor.
Here is my webpage at my webpage at TU Dresden.
I am interested in simple groups of Lie type, finite and locally finite groups and their automorphisms, linear algebraic groups, profinite groups, existentially closed groups and their generalizations.
Here is my CV and my Habilitation thesis, which contains a summary of my research.
