Dr Jun Liu is currently a Reader in Computer Science, a full member of Artificial Intelligence Research Group (AIRG) at Computer Science Research Institute. Before he joined Ulster University, he was a Postdoctoral Research Associate at The University of Manchester, UK (Feb. 2002 - Dec. 2004), and a Postdoctoral Research Fellow at Belgian Nuclear Research Centre (SCK*CEN) (Mar. 2000 -Feb. 2002). He received the BSc. and MSc. degrees in Applied Mathematics, and PhD. degree in Information Engineering from Southwest Jiaotong University, Chengdu, China, in 1993, 1996, and 1999, respectively.

He has been working in the field of Artificial Intelligence for many years. His current research is focused on two themes: 1) knowledge-centralized data analytics under uncertainty for sensing decision making, with applications in management, engineering, and industry field etc. (e.g., safety and risk analysis; policy decision making; security/disaster management; and heath care and smart home); 2) logic and automated reasoning methods for intelligent systems. In particular: resolution-based automated reasoning methods, algorithm and tools with applications (including software verification and automated theorem proving); lattice-valued logics with focus on handling incomparability, inconsistency and imprecision. He has over 150 publications in these areas.

He has been a grant holder of several national and international research projects. He serves as an Associate Editor of IEEE Transaction on Fuzzy Systems, Knowledge-Based Systems, and Human-Centric Computing and Information Sciences, an Area Editor of International Journal of Computational Intelligence Systems, is also an Editor of Information Fusion Journal, Journal of Universal Computer Science, and International Journal of Knowledge and Systems Science. He is a Senior member of the IEEE and chairs the IEEE System, Man and Cybernetic (SMC) Society UK&Ireland Chapter (SMC28). He serves as chairs or co-chairs and program committees of a number of international conferences and workshops.

He is a Fellow of the UK Higher Education Academy, and teaches at both undergraduate and postgraduate level.
