About me
I am a PhD student at the University of Regensburg supported by the SFB 1085 “Higher Invariants” funded by the DFG, under the supervision of Bernd Ammann.My research is located in the field of differential geometry and mathematical relativity. More precisely, I currently 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.
