About me
I recently obtained my PhD under the supervision of
Bernd Ammann at
University of Regensburg.
During my PhD and still today I am 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.
