The aim of the proposed project is to shed light on the theoretical origin of neutrino masses and to explore the phenomenological consequences of the model predictions and of possible mechanisms giving rise to neutrino mass. The results of many upcoming experiments in the neutrino sector and beyond will be a crucial discriminator for models and will have to be followed closely. Apart from the usual neutrino oscillation observables, there are more model-dependent implications of neutrino mass models, for instance lepton flavor violating decays and electric dipole moments in the charged lepton sector, or processes involving new particles at colliders such as the LHC. The connection to the baryon asymmetry of the Universe, to dark matter and to proton decay will also be studied. Phenomenology will also be focussed on: in particular, the implications of upcoming (precision) experiments on the neutrino mass and mixing parameters or the neutrino mass matrix will be investigated. The prospects of using high energy neutrino cosmic rays, neutrinoless double beta decay (including analogous processes) and new experimental ideas to probe the parameters of neutrino physics will also be explored.
