In the last several decades, neutrino oscillations have gone from an experimental anomaly to robust evidence for beyond-the-Standard-Model physics. While much has been learned since the first experiments, several aspects of oscillations remain unknown, including the degree to which CP is violated in the lepton sector. In this talk, I will explore our current knowledge of neutrino oscillations, and discuss how the next generation of experiments can further enlighten us. These upcoming experiments have the ability to test “standard” and BSM neutrino oscillation hypotheses, as well as a multitude of non-neutrino BSM physics scenarios.
