 Yu Wenfei received his Bachelor’s degree in Physics and Master’s degree in Theoretical Physics in the Department of Physics, Central China University in 1990 and 1993, respectively. In 1998 he obtained his Ph.D in Particle Physics in the Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences (CAS). He had worked in the Division of Particle Astrophysics of IHEP in 1994–2001 and visited the CGRO/BATSE group in Marshall Space Flight Center in 1996-1998. He also worked in the `Anton Pannekoek’ Institute for Astronomy of the University of Amsterdam and in the Department of Physics of the University of Illinois at Urban-Champaign in 2001-2006 before he joined Shanghai Astronomical Observatory (SHAO) in late 2006 through the CAS One Hundred Talents Program. His current interest is on X-ray timing, spectral and polarization probes of fundamental physics in black hole and neutron star X-ray binaries, and is engaging in developing a competitive group at SHAO with space and ground multi-wavelength observations of Galactic and extra-Galactic high energy transients.
