Lei Xu is a professor of Computer Science and Engineering
Chinese Univ Hong Kong (CUHK) where he first joined
as a senior lecturer in 1993, became a professor in 1996 and then took the
current chair professor position in 2002. He completed his Ph.D
thesis at Tsinghua Univ by
the end of 1986, then joined Dept. Math, Peking Univ
in 1987 first as a postdoc and then was exceptionally
promoted to associate professor in 1988 and to a full professor in 1992. During
1989-93, he worked at several universities in

has published dozens of jounral papers and also many
papers in conference proceedings and edited books, covering the areas of
Statistical Learning and Neural Networks, Financial Engineering, Computer Vision
and Pattern Recognition, Signal Processing, and Artificial Intelligence. Also,
he has given over 50 keynote
/invited / tutorial lectures at major international conferences on
Computational Intelligence and Neural Networks, and has been internationally
known with his several well-cited contributions on adaptive PCA and
independence learning, classifier combination and mixture model based learning,
rival penalized competition, etc, as well as his Bayesian Ying-Yang unified
statistical learning system and theory. Also, he and his colleague E.Oja's invention on Randomized Hough Transform has a
widely impact in the field of pattern recognition and computer vision too.

etc. Prof. Xu has also been serving as a member of
engineering panel, Hong Kong RGC research committee (2001-06), a member of
selection committee, Chinese NSFC/HK RGC Joint research scheme (2002-05),
external expert for Chinese NSFC information science panel (2004-06), and an
nominator for the prestigious Kyoto prize (2003,2007).
Prof. Xu
is a Fellow of IEEE (2001- ), Fellow of IAPR (International
Association for Pattern Recognition) (2002-), member
of European Academy of Sciences
(2002-). He has been listed in many international biographical
publications. Prof Xu has received an 1995 International
Neural Networks Society Leadership Award and several Chinese national
prestigious academic awards, including 1993 Chinese National Nature Science
Award, 1988 Chinese State Education Council FOK YING TUNG Award, and
the second of the 10 winners of the 1988 BEIJING YOUNG SCIENTISTS PRIZE.
Following the 2004 winner Prof Amari and the 2005
winner Prof. Fukushima,
recently Prof. Xu has received the 2006
