I am a physicist working on neutrino oscillation experiments. I have so far contributed to the measurement of four out of the seven fundamental neutrino oscillation parameters, including the solar neutrino mass splitting (delta-m-squared-21) and its mixing angle (theta-12), the atmospheric neutrino mass splitting (delta-m-squared-31), and the smallest neutrino mixing angle (theta-13). My current research aims to determine the remaining unknown parameters: the neutrino mass ordering (MO) and the CP-violation phase in the lepton sector (delta-CP).
