About me
I recently started as a post-doc at KTH Stockholm in the group of Klaus Kröncke and Mathias Dahl. My research there is funded by the DFG through the Walter-Benjamin grant no. 556505019. I obtained my PhD under the supervision of Bernd Ammann at University of Regensburg. During my PhD and a short time afterwards, I was supported by the SFB 1085 “Higher Invariants”, funded by the DFG.My research is located in the field of differential geometry and mathematical relativity. More precisely, I use spinoral methods to investigate the dominant energy condition for initial data sets. This has connections to positive (or non-negative) scalar curvature for Riemannian manifolds and Lorentzian special holonomy.
