Direct Dark Matter Searches

Direct searches for dark matter are motivated by the fact that we have compelling evidence for the existence of dark matter, but we have yet to observe it directly. Dark matter is thought to make up around 85% of the matter in the universe, yet we cannot see it or interact with it through any known force except gravity. This has led to a wealth of theories that postulate the existence of new, undiscovered particles that make up dark matter.
Direct searches for dark matter involve looking for interactions between these hypothesized dark matter particles and ordinary matter in a laboratory setting. These experiments typically involve detecting the energy or momentum transferred in the interaction between a dark matter particle and a target nucleus or electron. If such interactions are observed, they would provide direct evidence for the existence of dark matter.
The search for dark matter particles is one of the most important scientific endeavors of our time. Not only would their discovery revolutionize our understanding of the universe, but they could also have important implications for particle physics, astrophysics, and cosmology. For example, the nature of dark matter could help explain the observed structure of galaxies and the large-scale structure of the universe, and could provide insights into the properties of particles beyond the Standard Model of particle physics.


My group focuses on direct searches for Light Dark Matter and bosonic Dark Matter candidates with the CRESST experiment in the "Laboratori Nazionali del Gran Sasso (LNGS)" undeground laboratory in Italy, with the proposed DARWIN experiment, and with the proposed DELight experiment to be built in Baden-Württemberg.


In addition to data analyses we are working on investigating the sources of near-threshold excess rates, on the optimization of trigger algorithms, both for offline and real-time event selections, and on the design and development of DAQ systems.
