My research is with the T2K neutrino experiment in Japan that first observed the muon type neutrino oscillation into the electron type neutrino. Our CSU group members designed, built and operated neutrino detectors, analyzed T2K data and published neutrino and antineutrino cross sections. Currently, the T2K collaboration is studying antineutrino oscillations that indicate charge-parity (CP) violation.
