Stefan Funk is a professor at the Erlangen Centre for Astroparticle Physics (ECAP). Before coming to ECAP Stefan Funk was a faculty member in the Physics department at Stanford University and the SLAC National Accelerator Center in the Kavli Center for Particle Astrophysics and Cosmology (KIPAC). His research in the field of astroparticle physics is centered on the search for the origin of cosmic rays and the understanding of dark matter. He is a member of the Fermi-LAT (Large Area Telescope) satellite detector and of the H.E.S.S.-Experiment (High Energy Stereoscopic System), a system of imaging Cherenkov telescopes, located in Namibia. He is a member of the Cherenkov Telescope Array (CTAO), a next-generation flagship astroparticle physics project to observe gamma rays at the highest energies.
Besides his activities in high-energy astrophysics, Stefan Funk actively develops technology for the next-generation gravitational wave detector (phase camera) and pursues technlogy transfer into other areas, such as medical physics or material sciences.
Since November 2014 he holds the chair of physics at FAU Erlangen-Nürnberg.
