Günter Sigl

Günter Sigl is full professor of theoretical physics at Universität Hamburg since 2007. His main research is at the interface of particle physics with astrophysics and cosmology. In particular he is working on cosmic ray physics, also as a member of the Pierre Auger experiment and co-developer of our public software package CRPropa for simulation of high energy cosmic ray propagation in a structured Universe, hadronic physics in the context of air showers, multi messenger studies including gravitational waves, oscillation phenomena involving neutrinos and axions, indirect detection of dark matter, and the origin and evolution of cosmic magnetic fields in astrophysical plasmas and in the early Universe.

Outside working he likes running, hiking and climbing.
