Theories of Neutrino Masses

The discovery of neutrino oscillations and the subsequent measurements of the neutrino mass-squared differences and the lepton mixing angles over the past decade(s) have reinvigorated the quest to elucidate the physics that underlies the origin of the fermion masses in the Standard Model. This talk will provide a summary of the current status of theoretical approaches to the origin of neutrino masses and lepton mixing parameters, and their prospects in the present and forthcoming era of precision neutrino experiments.
