Welcome

I am Jonathan, a PhD student at the Max Planck Institute for Physics in Munich, Germany, in the Quantum Field Theory Group of Johannes Henn. My position is funded by the Max-Planck-IAS-NTU Center for Particle Physics, Cosmology and Geometry. I am also co-supervised by Ivo Sachs at LMU Munich, where I previously did my MSc in Theoretical and Mathematical Physics (joint program with TUM).

My research focuses on the interplay between theoretical high-energy physics and primordial cosmology. In a nutshell, I develop computational methods to find signatures of novel physics in cosmological data from the early universe.

Archery

Apart from doing physics, I have strong interests in art, literature and - most importantly - sports: I spend the majority of my free-time shooting arrows.
