 Research Interest

  Experimental neutrino phyiscs and search for new phyiscs beyond the Standard Model is a very important research direction in particle physics and nuclear phyiscs. I am interested the following fields: (1) Detection of Supernova neutrion and cross-sections of low energy neutrino interaction.(2) Determination of neutrino mixing angles. (3) Neutrino oscillation study using long base line accelator neutrino. (4) Search for CP violation and evidence of new phyiscs beyond the Standard Model using rare kaon decay.  (5) Determination of strange quark mass and Vus in CKM matrix using the strangeness tau lepton decay.
