I am an associate professor position at the CP3-origins center at the University of Southern Denmark in Odense. My group is supported by an ERC Starting grant, see the project website for more information.
I am a member of multiple international research collaborations running and building observatories for gamma-ray radiation from space (CTA, Fermi-LAT, H.E.S.S.) as well as particle physics (ALPS).
Before starting my professor position, I was a research group leader in Hamburg, a Marie Curie Research fellow at the Erlangen Centre for Astroparticle Physcs (ECAP), a Feodor Lynen Research fellow of the Humboldt foundation at Stanford University and the Kavli Insitute of Particle Astrophysics and Cosmology (KIPAC) and a return fellow in the ALPS group at DESY. I have been a post-doc at the Oskar Klein Centre at Stockholm University in Jan Conrad's group.
Originally, I am from Hamburg, Germany, where I also did my PhD in Prof. Dieter Horns' group. My masters thesis (in German) is available here.
