He has contributed many effective methods to different aspects of handwritten document analysis, including image pre-processing, feature extraction, classifier design, and character string recognition. His algorithms have yielded superior performance, and have been transferred to industrial applications including mail sorting and form processing. He has published over 170 technical papers at prestigious international journals and conferences, including IEEE TPAMI, Pattern Recognition, IEEE TNN, ICPR, ICDAR, CVPR, AAAI and IJCAI. He won the IAPR/ICDAR Young Investigator Award of 2005, and received the Outstanding Youth Fund of NSFC in 2008.
