### Work

I am currently employed at the University of Vienna in the group of David Fajman, which is part of the of the Gravitational Physics group. This position is funded by the Austrian Science Fund FWF through the project "Relativistische Fluide in der Kosmologie".

My reasearch interests include various topics in geometric analysis with a focus on mathematical cosmology. Hence, in my research I investigate the solutions and stability properties of partial differential equations on curved manifolds motivated by Einsteins theory of general relativity.
