In this talk, I will mainly discuss the phenomenology of neutrino oscillations and neutrino mass. Regarding neutrino oscillations, my work concentrates on the measurement of the Dirac CP phase, including proposing the use of neutrinos from muon decay at rest to improve the sensitivity of next-generation neutrino experiments to the CP phase, as well as studying the impact of new physics on CP measurements. Concerning neutrino mass, my research focuses on the origin of neutrino masses, where I proposed using the time delay of supernova neutrinos to distinguish different neutrino mass origins.
