I am an IT consultant for Logistics Execution. My dissertation at the CAU of Kiel, GE was about modular group algebras and their unit groups. I am still interested in algebraic topics in my free time (group algebras, character theory, symmetric group, associative algebras, Lie theory, connection between disciplines like unit groups and associated Lie algebra of an associative algebra, Solomon-Tits-Algebras, Wedderburn-Malcev-Theorems). I like to write books about algebra in publishing services.
