I am a mathematician working at the intersection of geometry, analysis and topology with a particular focus on problems involving the scalar curvature of a Riemannian manifold. Recently, my main passions have been to establish aspects of a comparison geometry for lower scalar curvature bounds as well as to study closely related geometric problems in the context of general relativity. Moreover, I am interested in topological properties of spaces of Riemannian metrics with positive scalar curvature. A broad o
Since 2024 I am leading the ERC Starting Grant project COMSCAL ( press release ). My own position is funded by the Heisenberg Programme of the DFG.
I am a professor (temporary W2) at the Mathematical Institute of the University of Münster , where I am an investigator in the Cluster of Excellence Mathematics Münster and a member of the CRC 1442 Geometry: Deformations and Rigidity . I also participate with a subproject in the DFG priority programme Geometry at Infinity .
