With a background in experimental particle physics, I have been a full professor in the Department of Physics since 2024. I have worked on experiments investigating CP violation (B physics at Fermilab) and the search for new physics beyond the Standard Model through the rare decay of the muon into an electron and a photon (MEG and MEG-II experiments at the Paul Scherrer Institute near Zurich). I contributed to the development of innovative detectors (the liquid xenon calorimeter for the MEG experiment and the drift chamber for MEG-II), as well as readout and trigger electronics, and data analysis.
Since 2014, I have been working in experimental cosmology as a way to explore fundamental interactions at energy scales not accessible to particle accelerators. In particular, I focus on the search for experimental signatures of cosmic inflation—an exponential expansion believed to have occurred in the very first instants of the universe—triggered by a mechanism analogous to the Higgs mechanism but operating at energy scales comparable to Grand Unified Theories (GUT).
For these experiments—most notably the LiteBIRD satellite, which is scheduled for launch in the early 2030s—I am developing, together with my group and in collaboration with the Italian National Institute for Nuclear Physics (INFN) and the Italian Space Agency (ASI), innovative sensors and readout electronics based on superconducting and quantum technologies. These include, for example, TES (Transition Edge Sensors), KIDs (Kinetic Inductance Detectors), and SQUIDs (Superconducting Quantum Interference Devices), which we study in the lab using advanced cryogenic instrumentation.
I am also interested in the applications of these technologies beyond cosmology, particularly for neutrino detection and dark matter searches.
