About me

I am a PhD student in mathematics at the University of Regensburg, supported by the SFB 1085 Higher Invariants. My advisor is Clara Löh.

Broadly speaking, i can be interested in most forms of (pure) mathematics, including computer science. Currently, my main interests lie within algebraic topology and (∞-)category theory.

Particularly, i am working on topics related to functorial semi-norms, such as the ℓ¹-semi norm on singular homology. The latter is the main ingredient in the definition of simplicial volume.
