About me

I am a postdoc in the group of Roman Sauer. The common denominator of my research interests is the study of (discrete) groups with tools from algebraic topology and operator algebras, as well as geometry and sometimes computer calculations.

The main focus of my current research is the semidefinite programming approach to property (T) and similar spectral properties of operators coming from group representations. I have also worked on thin monodromy groups, bounded cohomology, equations over groups, and index-theoretical obstructions against positive scalar curvature.
