The particle physics has been developed by both precision measurements and energy frontier. These two directions are closely connected with each other. The muon anomalous magnetic moment (g −2) was very precisely measured at Brookhaven E821 experiment, and it deviates from a Standard Model prediction with significance of around 4σ. The situation of the muon g−2 will become more clear in a few years at Fermilab’s experiment. The muon g−2 anomaly implies the existence of new physics beyond the Standard Model such as supersymmetry (SUSY) not far from the weak scale. Combining the anomaly with other experimental constraints, we are led to a unique SUSY mass spectrum, which should show up at the LHC and future collider experiments. The new physics will also be tested by precisely measuring lepton flavor violations of the muon.

He had been a postdoctoral research fellow at the University of Tokyo from 2010 to 2014 and at INFN Rome from 2014 to 2016. He has worked on model building, phenomenology and cosmology of new physics beyond the Standard Model such as supersymmetry.
