Dr. Xiaoqing “Frank” Liu joined the University of Arkansas in July 2015 and is currently a professor and department head and holds the Rodger S. Kline endowed leadership chair in the Department of Computer Science and Computer Engineering. He served as a professor and an associate chair for graduate studies and external affairs in the Computer Science Department at the Missouri University of Science and Technology, formerly University of Missouri-Rolla, prior to coming to the University of Arkansas. 

Dr. Liu's research interests include software engineering, service computing, collective intelligence, web-based argumentation, intelligent systems, and software applications.  He published numerous refereed journal and conference papers and book chapters and served as principal or co-principal investigators on more than twenty-five sponsored research projects and an industrial partnership.  He made notable contributions in the areas of software modeling, on-line argumentation based collaborative decision support, web service discovery and recommendation, and software quality and process management.

Dr. Liu taught many computer science and software engineering courses, including offering distance learning graduate level software engineering courses for more than fifteen years. He is also active in professional services. He was a program committee chair for the 2008 IEEE International Conference on Computer Software and Application (COMPSAC) and served as a technical program committee chair for the Annual International Conference on Collaboration Technologies and Systems (CTS) five times from 2011 to 2015. He always welcomes research and education sponsorship, partnership, and collaboration opportunities and constantly recruits excellent PhD students with assistantship support to join his research group.
