Research interests


My research interest is particle astrophysics, especially the search for dark matter: it provides a fascinating connection between observations of the largest structures in the universe with the physics of elementary particles. Astronomical observations of dark matter are also one of the strongest indications of a new physics beyond the standard model of particle physics.

Since the days of my doctoral studies I have contributed to the direct search for dark matter: in the beginning as part of the EDELWEISS experiment, now as a member of the CRESST and EURECA collaborations and the DEPFET project. An additional research interest is adapting the CRESST detector technique for the measurement of coherent neutrino nucleus scattering (CNNS) within the $\nu$-cleus project. In all these cases I provide studies of the relevant background processes, and for EURECA I also coordinate the related working group within the collaboration. In the case of CRESST I also contribute to developing the necessary detector electronics.

Common to all of these experiments is the fact that the signal rate is very low. Therefore, a precise knowledge of the background contribution is crucial. The background sources cover a wide range of individual processes and energy scales, e.g. neutron production by cosmic muons at TeVs, but also eV energy depositions by Auger electrons caused by intrinsic contaminations of the detector with products of the U/Th decay chains. I study the contribution of each process via Monte Carlo simulations based on the software framework Geant4.

Besides background simulation, I’m also interested in detector development. During my doctoral studies I developed a neutron multi meter and the related data acquisition electronics for measuring muon-induced neutrons. Currently, I am coordinating the development of new SQUID-based readout electronics for the next iteration of CRESST.

Outreach activities


On the Vienna „Dark Matter Day“ (31 Oct. 2017) I presented galactic rotation curves as one hint to dark matter.

In the exposition „Spurensuche - Die Bausteine des Universums“ I participate as one of the guides, explaining the exhibits during the opening ceremony (11 Sept. 2014).
