Research activities

I work as a theorist at the experimental frontiers of fundamental physics.
As a student I started working on supersymmetric unification.
Next I switched my attention to neutrino oscillations, a field that was entering in its golden age.
Later, my main interests shifted towards leptogenesis and Dark Matter, where I proposed predictive theories.
My research activity also contains excursions in flavour physics, vacuum decay theory, astro-particle physics, precision physics, collider physics,
Higgs physics, quantum gravity, supergravity, thermal field theory, cosmology, one analysis of cosmological data, one high-energy experimental paper, and topics outside physics.
During 2010-2020, with the beginning of the LHC experiments, my interest focused on high-energy physics; we worked out the main implications of the data, and proposed alternative theories of the origin of the electro-weak scale and of the Planck scale, with implications for inflation.
