• 
• Resource (actively updated): With the help of LLMs, Shujun converted his old static call for papers page into a dynamic page with many useful features.
• Resource (last updated on 20 March 2026): Shujun is maintaining an online bibliography of SoK (Systematization of Knowledge) papers.
• Professional Activities: As part of the EPSRC-funded CRANE NetworkPlus, Shujun is leading the establishment of a new learned society in cyber security research, as the Chair of a Learned Society Preparation Committee (LSPC), also known as CRANE's Learned Society Formation Working Group (LSFWG).
• Selected Public Engagement Activities: Shujun has coordinated many school outreach activities, e.g., multiple NCSC CyberFirst events for local schools in Kent and Medway. In 2023 he co-founded three local community building bodies for the Kent and Medway region and since then has been (co-)leading their activities: KMCSN (Kent & Medway CyberSchools Network), KMCS3 (Kent & Medway Cyber Security Student Society), and KMCC (Kent & Medway Cyber Cluster). He led the 2023-24 iCSS-KMCC-KMCS3 CyberAnything Competition and the 2024 iCSS Cyber Security Awareness Month (which included the 2024 "Creative Cyber" Exhibition as a major highlight). Between 2022 and 2026, he coordinated the production of the following three animated videos for cyber security awareness.

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, as a Senior Lecturer and then a Reader (Associate Professor). From 2014 to 2017, he was 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 November 2017, he has been a Professor of Cyber Security at the University of Kent, leading the Security Group of its School of Computing and the university-wide Kent Interdisciplinary Research Centre in Cyber Security (KirCCS). From January 2021, he has been the Founding Director of the Institute of Cyber Security for Society (iCSS), the third university-wide institute at the University of Kent.

Since 2000, Shujun Li has published over 100 scientific papers with six Best Paper Awards and two Honorable Mention Awards, and his research interests are mainly on cyber security (including usable security and user privacy, digital forensics and cyber crime, cyber law and cyber/data/AI governance, security and privacy in online social networks, mobile security and systems security in general, human behavior/legal aspects/scam/crime/privacy aspects and AI/multimedia related to distributed ledger techonologies and cryptocurrencies, information hiding), data analytics and multimedia computing (including visual quality assessment and image/video coding), and human factors (including usability, human behaviors, and accessibility), applications (i.e., NOT theory) of artificial intelligence including LLMs and NLP, cyber and AI education and learning. He also keeps his older research interests in applications of discrete optimization to multimedia computing especially recovering of unknown/missing/lost/manipulated information in digital images and videos (see here for a representative publication), and interdisciplinary topics betwen nonlinear science (chaos/fractals) and electronic engineering and computer science epecially digital degradation of chaotic systems in the digital domain (see here and here for two representative publications) and cryptanalysis of chaos-based secure communications schemes and digital ciphers. More about Shujun's research interests can be found here. Shujun Li is a Fellow of the BCS, a Senior Member of the IEEE, a Professional Member of the ACM 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.
