Christoph Hilmes

I am a PhD student at Universität Bielefeld under the supervision of Dawid Kielak. Before, I did my Bachelor and Master studies at WWU Münster and wrote my Master thesis Small cancellation in Artin groups under the supervision of Linus Kramer.

Here you can find the homepage of our working group.

Currently I am working on Nielsen Realisation for right-angled Artin groups.

Research interests

  • Geometric and combinatorial group theory
  • Automorphisms of right-angled Artin groups
  • Hyperbolic (esp. small cancellation) groups
  • Low-dimensonal topology
  • Cube complexes


  • 2014 to 2018: Tutorials in Münster for the courses Analysis I, Elementary Number Theory, Introduction to Geometry & Topology and Algebraic Topology.
  • 2018 and 2019: Organisation of the tutorials for the course Analysis I in Bielefeld.
