Xiaoqiang Cai received his B.Eng. degree from the Harbin Shipbuilding Engineering Institute in 1982 and his M.Eng. and D.Eng. degrees from Tsinghua University, in 1985 and 1988 respectively. During 1989-91, he conducted postdoctoral research at The University of Cambridge and The Queen's University of Belfast. He was Lecturer of Applied Mathematics at The University of Western Australia, before he joined The Chinese University of Hong Kong as Lecturer in 1993. He had been the Chairman of the Department of Systems Engineering and Engineering Management during 1996-2003, and Professor since October 2000. His research at present concentrates on scheduling models and algorithms, logistics management, network optimization, and portfolio optimization. He has published extensively in leading journals in these areas, such as Operations Research, Management Science, Naval Research Logistics, IIE Transactions, and IEEE Transactions. He is on the editorial boards of several international journals, including IIE Transactions on Scheduling and Logistics, and the Journal of Scheduling.
