Neutrino phenomenology and the flavour puzzle

My research lies at the interface between neutrino physics, particle phenomenology and cosmology. With the Bari group I have contributed to a long line of global analyses of neutrino oscillation data, combining solar, atmospheric, reactor and accelerator experiments to determine the parameters of leptonic mixing with state-of-the-art precision.

As measurements enter the subpercent regime, these results constrain the neutrino mass ordering, leptonic CP violation and the absolute mass scale, and probe possible signatures of physics beyond the three-neutrino paradigm. A complementary line of work investigates modular invariance as a candidate symmetry underlying the flavour structure of quarks and leptons.
