Professor Hai-fu Fan and colleagues at the Institute of Physics have been long engaged in the study of direct methods in crystallography. Recent progresses were made in the iterative dual-space direct-method SAD （Single Anomalous Diffraction） phasing proposed in 2004 and the iterative dual-space direct-method MR （Molecular Replacement） model completion proposed in 2006. These significantly improved conventional SAD phasing and MR model completion （see Figures 1 and 2 respectively）.
