Received a Bachelor of Science in Applied Mathematics from Chongqing University in 1986, a dual Master's degree in Software Engineering and Computational Mathematics from Xi'an Jiaotong University in 1989, and a PhD in Computer Science Theory and Engineering from Chongqing University in 1998. From 1999 to 2001, he He was a postdoctoral researcher at Hong Kong Baptist University, a visiting scholar at the University of Provence in France from 2002 to 2003, and a visiting scholar at the University of Guelph and the University of Toronto in Canada from 2005 to 2006.
Teaching situation
p>Currently, he is the deputy dean of the School of Computer Science and Engineering and the School of Exemplary Software of the University of Electronic Science and Technology of China, director of the International Wavelet Analysis Application Research Center, editor-in-chief of International Progress on Wavelet Active Media Technology and Information Processing, and international academic journal Deputy editor-in-chief of the International Journal of Wavelet Multiresolution and Information Processing. He concurrently serves as a review member of the National Science and Technology Awards, a review member of the National Natural Science Foundation of China, and a technical advisor to the People's Republic of China and the Ministry of Public Security. He was awarded the title of 2004 Chairman of the International Computer Academic Conference, the 3rd International Academic Conference on Wavelet Analysis and Applications (ICWAA), and the 2nd International Academic Conference on Intelligent Media Technology (ICAMT). He is a well-known expert who is very active in the field of wavelet analysis and information processing research in the world. .
Scientific research status
He independently proposed and systematically established the "acceleration method of wavelet transform", "vector product wavelet transform theory", and "electronic signature system based on wavelet analysis" internationally. " and other series of theories and methods. This theory is more than an order of magnitude faster than the famous Mallat algorithm proposed by Mallat, the founder of wavelet analysis, and the effect and quality are far better than the Mallat algorithm. This has paved the way for the application of wavelet theory in many aspects such as signal processing and information analysis. It provides advanced algorithms, provides a theoretical basis for real-time processing and productization of wavelet analysis, and opens up broad application prospects for wavelet analysis. For the first time in the world, he proposed "the most secure transmission model and method of information based on the 'three major characteristics' (machine characteristics, document characteristics, and human body characteristics)" and made important contributions to network and information security, which are currently hot research topics. He has presided over 30 projects including the National 863 High-tech Project and the National Natural Science Foundation of China. He has published 150 important papers in famous academic journals at home and abroad, 48 papers indexed by SCI, EI, ISTP, the three major international retrieval agencies, and published 15 academic monographs, 2 of which have been revised and reprinted many times. High-tech products such as "Wavelet Fingerprint Encryption System" and "Distributed Network Monitoring System" developed by him have produced extensive economic benefits and social impact
