I do research in astroparticle physics, with focus on neutrinos and dark matter, and their possible interconnections. In particular, my research interests are: the matter-antimatter asymmetry of the Universe and its dynamical generation at early epochs, especially through the leptogenesis mechanism; testability and phenomenology of seesaw models, models with flavour symmetries and dark sectors; active galactic nuclei as laboratories for sub-GeV dark matter and beyond the Standard Model physics; high-energy neutrino astrophysics.
