Group cohomology is a mathematical field that sits at the intersection of algebraic topology, commutative algebra, representation theory, group theory, invariant theory, and homological algebra. It has its origins in the late 1800s, and started as a proper own field in the 1930s/1940s. 

To get a feeling for what I do, read below for an intuitive and non-technical introduction. In more technical terms I am working on the mod-p group cohomology certain p-groups and their fusion systems. In my  PhD thesis  I looked  into the 2x2 special linear and general linear groups with entries in the integers mod p^n, n>1. This is a big project, and still center of ongoing research.

With Jason Semeraro I am working on fusion systems with a special interest in sharpness.

In 2024 I had the pleasure of spending four weeks at the Isaac Newton Institute satellite programme Topology, Representation Theory, and Higher Structures . Here is a recording of the talk I gave in week three.
