I am a PhD student of Ulrich Thiel at RPTU Kaiserslautern-Landau.
My research interests lie in algebraic geometry and representation theory.
More precisely, I am interested in (the existence of) symplectic resolutions, symplectic reflection algebras and Cox rings.
I also always like to see things from an algorithmic point of view and currently help implementing algorithms for invariant theory in OSCAR; see also my github profile.
You can find my CV here.
