Fan is prof. of physics at the Inst. of Physics, Chinese Acad. of Sciences (CAS). He is a member of CAS (1991). He works in the field of crystallographic methodology and proposed a series of methods for solving small molecules, proteins, incommensurately modulated structures and for image processing in high-res. electron microscopy. He received the Natl. Natural Science Award of China in 1987, the Ye Qi-sun Prize for Physics from the Chinese Physical Society in 1991, and the Tan Kah Kee Science Award in Maths. and Phys. from CAS in 2006. In collaboration with Professor M.M. Woolfson (FRS, UK), he co-authored the book Physical and Non-Physical Methods of Solving Crystal Structures (Cambridge U. Press, 1995). Recently Fan proposed a method using of X-ray free electron laser sources, for simultaneous X-ray phase identification and structure solution for multiphase polycrystalline samples.
