Neutrinos are neutral particles in the Standard Model that interact only via the weak interactions. They are closely related to the charged leptons (electrons, muons, taus) and the observation that they undergo flavour transitions won the Nobel prize in 2016. These flavour transitions also imply that neutrinos have mass, which is not the case in the Standard Model. Together with my collaborators, I study how future neutrino experiments can probe the model parameters as well as the physics that give rise to neutrino masses.
About a quarter of the energy density in the Universe is composed of a yet unknown type of matter, called dark matter, whose effects we have so far only observed through its gravitational effects. This abundance of dark matter corresponds to about five times the amount of ordinary matter (the rest of the energy density seemingly being in the form of dark energy). My research in this field is focused on the astrophysical effects and distribution of dark matter, its creation in the early Universe, and the possible observable effects of different dark matter models.
