Most of my research career has been centered on properties of subatomic particles, their interactions and the fundamental symmetries, which govern these interactions. At first, I studied a rare K meson decay of K+→ at the Brookhaven National Laboratory in the U.S.A to determine the Kobayashi-Maskawa quark mixing matrix elements. And then, I worked on a search for violation of the time-reversal invariance by using a K meson decay at KEK, Japan, and improve the upper limit. From 1996, I have started working on the physics with muons and neutrinos. For the neutrinos, I worked with the Super-Kamiokande and the K2K long-baseline neutrino experiments to study neutrino oscillation, and also am working on R&D for future accelerator projects of a Neutrino Factory and a Muon Collider in the framework of the international collaboration. For the muons, I am working on a search for charged lepton flavor violation to make a discovery of new physics phenomena beyond the Standard Model of physics. We have proposed the phase-1 experiment called COMET to search for μ-e conversion in a muonic atom with an experimental sensitivity better than 10-16, and then the phase-2 experiment called PRISM with a sensitivity of 10-18. As a pilot project of the highly intense muon beam source, we have initiated the MUSIC facility to provide a muon beam of the world-highest intensity at Research Center for Nuclear Physics, Osaka University. The MUSIC is scheduled to operate in 2010, and a broad range of muon science, from particle physics to application, can be explored at the MUSIC.

Prof. Yoshitaka Kuno graduated from the University of Tokyo in 1984. Then, he became a research associate at the University of Tokyo in 1984. In 1985 he moved to TRIUMF, Canada, as a research associate, and in 1988 became a research scientist (a tenure position) at TRIUMF. In 1992, he became an associate professor at the National Laboratory for High Energy Physics (KEK) in Japan, which was renamed to the High Energy Accelerator Research Organization (KEK) later. In 2000, he became a full professor at Osaka University.
