Kangzhan received his PhD in 1992 from Fudan University specializing in the use of molecular beams and laser technology to study the dynamics of semiconductor surface reactions. After spending one year as a post-doc with Prof. Ned Green of Brown University studying the energy transfer between gas molecules and solid surfaces, he joined the group to become our soft X-ray photoemission expert.  He ran the U8 beamline at the National Synchroton Light Source from 1995 to 2000.  He know works for a start-up company called Torrex, Inc in Silicon Valley.  His papers while in the group focused on studies of the silicon/silicon oxide interface.
