Wang Yifang (Chinese: 王贻芳; born February 1963 in Jiangsu) is a Chinese physicist. He is an elementary particle and accelerator physicist. He is director of the Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences in Beijing and known for contributions to neutrino physics, in particular his leading role (with Kam-Biu Luk) at Daya Bay Reactor Neutrino Experiment to determine the last unknown neutrino mixing angle θ 13 (see neutrino).[1]
After earning his bachelor's degree in physics at Nanjing University (1984) he was with Samuel CC Ting at the L3 experiment the Large Electron-Positron Collider (LEP) of CERN. Wang worked for the University of Florence, Laboratory for Nuclear Science of the Massachusetts Institute of Technology and at Stanford University. In 2001 he returned to China at IHEP as a professor and deputy director of the Centre for Experimentaphysik. In 2011 he was its director.[2]
Since 2014 Wang been Director of the Jiangmen Underground Neutrino Observatory (JUNO) in Southern China leading the experiment in an effect to determine the neutrino mass hierarchy with neutrinos from nuclear reactors.[citation needed]
