Theoretical High Energy Physics
Fascinated by the rich structure of quantum field theory and general relativity, I am conducting research at the interface of particle physics, astrophysics and cosmology. My primary goal is to unravel the physics governing the early Universe, in particular, the nature of dark matter. To reach this goal, I study variants of dark matter genesis in the early Universe aiming for a deeper understanding of the involved mechanisms and processes. This allows me to explore realizations of these scenarios in well-motivated particle physics models, i.e. contenders for the “next Standard Model”. Furthermore, I am interested in exploring the complementaritiy of searches for new phyiscs, e.g. at colliders, via (in)direct detection and cosmological observables, to constrain models of dark matter and gain knowledge about the most pressing questions of fundamental physics today.
