§About Me
I'm a PhD student in Mathematics at the Karlsruhe Institute of Technology (KIT) under the supervision of Claudio Llosa Isenrich and Roman Sauer. The KIT is also where I completed my master's degree.
§Research Interests
My research interests are in geometric group theory and algebraic topology, with a focus on finiteness properties and quantitative invariants such as (homological) filling functions of groups. In particular, I am interested in the behaviour of these invariants in the non-finitely presented setting.§Preprints
