Hello, I am a scientific assistent at the Institute of Mathematics of the Martin-Luther-Universit├Ąt Halle Wittenberg.
There I am working with professor Rebecca Waldecker.

Consultation hours:

Just send an email to make an appointment for a virtual Meeting!

Interests of research:

I am focusing on finite groups.
In particular I am interested in the local analysis of finite groups and subgroup lattices.
Additionally I study algebraic aspects in functional equations especially Tabor groups that occur in investigations of stability of functional equations
