I am interested in theories beyond the Standard Model of particle physics and in particle cosmology, i.e. the interplay of particle physics, cosmology, and astroparticle physics. In particular I am interested in the phenomenology of particle dark matter models in theories beyond the Standard Model.|
I have been working on the phenomenology of decaying dark matter models in the context of indirect dark matter searches with a focus on gravitino dark matter models with R-parity violation. A main aspect of this work is the study of dark matter decay signals in gamma rays, antiprotons, positrons, neutrinos, and antideuterons that could be observed in earthbound and satellite cosmic-ray experiments.
