Since 2000, Shujun Li has published over 100 scientific papers with five Best Paper Awards and one Honorable Mention, and his research interests are mainly on cyber security (including usable security and user privacy, digital forensics and cyber crime, security and privacy in online social networks, mobile security and systems security in general, information hiding, human behavior/scam/crime/privacy aspects and AI/multimedia applications using distributed ledger techonologies, but NOT cryptography and purely theoretical aspects), 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, education and learning since 2021. 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.

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.
