Dr. So’s research expertise is in the areas of operations and supply chain management, and business process improvement in manufacturing and service systems.
Dr. So has been on the faculty at the UCI Paul Merage School of Business for over 30 years, and had served as the Associate Dean of Undergraduate Programs (2009-2012, 2014-2016) and the Ph.D. Program Director (1998-2000). Prior to joining the faculty at UCI in 1989, Dr. So had worked at the AT&T Bell Laboratories for almost five years, where he served as an internal consultant to various AT&T manufacturing facilities. From 1996-98, Dr. So served as the Head of the Department of Management at the Hong Kong Polytechnic University. Dr. So also held Visiting Professorships at the University of Hong Kong, International University of Japan and the National University of Singapore.
Dr. So has published many research articles in major academic journals including Management Science, Operations Research, Manufacturing & Service Operations Management, IIE Transactions, Naval Research Logistics,Queueing Systems, and European Journal of Operations Research. Dr. So has frequently presented his research findings at academic institutions and professional conferences worldwide. He has served on the editorial boards of Naval Research Logistics, Production and Operations Management and Computer and Operations Research. Dr. So was a recipient of several research, teaching and service awards at UCI.
Dr. So has previously advised clients or conducted management workshops for a number of companies including, Southern California Edison, Nestle, Federal Reserve Bank of Los Angeles, Ingram Micro, Conexant Systems, Microsemi, Orient Overseas Container Limited, and Hong Kong Hospital Authority.
