I am a postdoctoral researcher at the RWTH Aachen University, as part of the working group of Prof. Dr. Daniel Robertz.
Research
My research interests lie in algebraic number theory, computer algebra and the representation theory of finite groups.
I am a member and junior speaker of the Integrated Research Training Group (IRTG) of the SFB-TRR 195 Symbolic Tools in Mathematics and their Application.
