I am a theoretical physicist with a focus on cosmology, currently working at the
Institute for Theoretical Physics
at Heidelberg University.
I am also the Scientific Coordinator of the
TRR33 "The Dark Universe"
, a collaborative research project between the Universities Heidelberg, Bonn and LMU Munich, funded by the German Research Foundation (DFG).
Before moving to Heidelberg, I had postdoctoral positions at the Technion (Israel) and ICG Portsmouth (UK), with shorter research visits at UNSW Sydney (AUS) and the Albert Einstein Institute in Potsdam (D).
I obtained my diploma in theoretical physics at KIT / University of Karlsruhe (November 2009), and my PhD in theoretical cosmology (defended in July 2013) at RWTH Aachen University.
In my spare time, I'm a passionate Cellist.
Here's our recording of Schindler's list (violin solo: Franz-Markus Siegert, cello solo: Cornelius Rampf, ensemble: Il Giardino):
The main focus of my research is cosmological structure formation. I'm interested in
how the today's observed large-scale structure of our Universe has formed.
More specifically, my research objectives include
- perturbation theory in standard and non-standard cosmological models,
- investigating the matter collapse and the break-down of the cosmological fluid equations ("shell-crossing"), and
- investigating the impact of photons and neutrinos in cosmological N-body simulations.
Applying state-of-the-art techniques borrowed from high-energy physics and mathematical fluid dynamics, I develop novel tools to determine the large-scale structure to high accuracy.
