Dr Jun Liu is currently a Professor in Computer Science, Director of Artificial Intelligence Research Center (AIRC) at School of Computing, Ulster University. 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) trust and explainable data-knowledge integrated AI decision model/system 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 270 publications in these areas.

He has been awarded over £18 Million of research funding from various funding bodies as grant holder and principle co-investigator. He is the current Chair of IEEE CIS Emergent Technologies Technical Committee (ETTC), also the past Chair of IEEE System, Man and Cybernetics (SMC) Ireland Chapter (SMC28). He is an IEEE Senior Member including IEEESMC and IEEECI. 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 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.
