Profile

Shujun Li was born in Yanzhou, Jining, Shandong, China. He received his BE degree in Information Science and Engineering from the Xi'an Jiaotong University (西安交通大学) in 1997, and received his PhD degree in Information and Communication Engineering in 2003 at the Institute of Image Processing, School of Electronic and Information Engineering, Xi'an Jiaotong University, supervised by Prof. Yuanlong Cai (蔡元龙教授) and Prof. Xuanqin Mou (牟轩沁教授). He has published more than 50 scientific papers, mainly in chaotic cryptography and multimedia security. During September 2003 to January 2005, he was a postdoctoral Research Assistant with the Department of Electronic Engineering, City University of Hong Kong (香港城市大学), under the supervision of Prof. Guanrong Chen (陈关荣教授). From June 2005 to January 2007, he was a postdoctoral fellow under The Hong Kong Polytechnic University (香港理工大学)'s Postdoctoral Fellowships Scheme, working at the Department of Electronic and Information Engineering with Dr. Kwok-Tung Lo (卢国栋博士). From March 2007 to June 2008, he was a Humboldt Research Fellow and doing his research at the FernUniversität in Hagen, Germany, under the host of Prof. Dr. Dr. Wolfgang A. Halang. Since July 1st 2008, he is a postdoctoral fellow of the Zukunftskolleg ("Future College"), Universität Konstanz, working as a junior group leader of the project "Secure Multimedia Computing" . Dr. Li is also a member of the Fachbereich Informatik und Informationswissenschaft (Department of Computer and Information Science), and affiliated with Prof. Dr. Dietmar Saupe's group on Multimedia Signal Processing.

As an important experience, from April to September in 2002, he did research on secure human-computer identification against peeping attacks (SecHCI), CAPTCHAs and visual/graphical passwords as a visiting student at the Microsoft Research Asia (MSRA, 微软亚洲研究院), Beijing, China, under the supervision of Dr. Harry Shum (沈向洋博士), who was the managing director of MSRA and now a vice president of the Microsoft Corporation.
