About me

I am a Postdoc in the differential geometry group at the Institute for Algebra and Geometry of the KIT. I obtained my PhD in Münster under the supervision of Johannes Ebert.


My research interest lies in algebraic topology and differential geometry. In particular I am interested in the interplay of curvature conditions (mostly positive scalar curvature) and cobordism theory.
