Brief Biography (CV)

Shujun Li received his BE degree in Information Science and Engineering in 1997, and his PhD degree in Information and Communication Engineering in 2003 under supervision of Prof. Yuanlong Cai (蔡元龙) and Prof. Xuanqin Mou (牟轩沁), both from the Xi'an Jiaotong University (西安交通大学). During 2003 to 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 supervision of Prof. Guanrong (Ron) Chen (陈关荣). From 2005 to 2007, he was a postdoctoral fellow funded by 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). From 2007 to 2008, he was a Humboldt Research Fellow and doing his research at the FernUniversität in Hagen, Germany, hosted by Prof. Dr. Dr. Wolfgang A. Halang. From 2008 to 2011, he was a 5-Year Research Fellow at the Zukunftskolleg (Institute for Advanced Study), Universität Konstanz, Germany, and a junior faculty member of the Department of Computer and Information Science, working closely with Prof. Dr. Dietmar Saupe's group on Multimedia Signal Processing. In September 2011, he joined the Department of Computing (renamed to Department of Computer Science in August 2015), University of Surrey, UK, and is currently working there as a Reader (Associate Professor). Since July 2014, he has been a Deputy Director of the Surrey Centre for Cyber Security (SCCS), leading the cross-cutting research theme Human Factors (known as Human-Centred Security between July 2014 and January 2017). Since December 2014, he has been the Director of PGR (Postgraduate Research, i.e. PhD) Studies of the Department of Computer Science (Computing), University of Surrey. He has also been a member of the University of Surrey's University Ethics Committee since May 2015. From November 2017, he will join the University of Kent as a Professor of Cyber Security, leading the Security Group of its School of Computing and the university wide Interdisciplinary Research Centre in Cyber Security.

Word Cloud of Shujun's Research (click to enlarge)Since 2000, Shujun Li has published over 90 scientific papers, and his research interests are mainly on cyber security (including usable security and user privacy, digital forensics and cyber crime, information hiding and digital watermarking, mobile security, security economics, network security, systems security, but NOT cryptography and purely theoretical aspects), multimedia computing (including image processing, image/video coding, and visual quality assessment), human factors (including usability, computational aspects related to human behaviours, and accessibility), applications of artificial intelligence (NOT theory) in cyber security and multimedia computing, applications of nonlinear science (chaos/fractals) in computer science and electronic engineering. More about Shujun's research interests can be found here. Shujun Li is a Senior Member of the IEEE (Computer Society, Signal Processing Society, Communications Society, Circuits and Systems Society, Cybernetics, Man and Systems Society, Society on Social Implications of Technology, Consumer Electronics Society), a Professional Member of the ACM (SIGSAC, SIGMM, SIGCHI, SIGCOMM, SIGCAS) and a Global Member of the Internet Society (ISOC). From 2009-2011 he was a member of MPEG (ISO/IEC JCT 1/SC 29/WG 11), and in 2012 was awarded an ISO/IEC Certificate of Appreciation for being the lead editor of ISO/IEC 23001-4:2011 "Information technology – MPEG systems technologies – Part 4: Codec configuration representation", the 2nd edition of the MPEG RVC standard.

Professional Activities

To Prospective Students

Shujun is actively seeking PhD students who are interested in various topics in cyber security, digital forensics, and multimedia coding. Click here to see a list of topics Shujun is currently offering to prospective PhD students.

Shujun is also actively seeking (visiting) UG/master's/PhD students who are interested in conducting short-term research projects under his supervision. This can be done either at Surrey locally or remotely via the Internet. He has been working with many UG/master's students from different countries (UK, Germany, China mainland, Hong Kong, Pakistan, Australia, Malaysia) on various projects many of which led to great publications (e.g. his ACSAC 2010 paper with two Pakistani UG students, his SOUPS 2011 paper with two Pakistani master's students and his hPIN/hTAN paper at FC 2011 with a German Diploma student). Currently, he is working with three master's students in China on a paper targeting a top security conference. Since 2012, he has been actively hosting visiting UG/PhD students from overseas especially China (including mainland and Hong Kong).
