Prof. Zhe George Zhang is a professor of Management Science in the Department of Decision Sciences at Western Washington University and a professor of Operations Management in Beedie School of Business at Simon Fraser University. He is also visiting professor of Sauder School of Business at the University of British Columbia. Dr. Zhang received his BS in Computer Science and MA in Economics from Nankai University, China; his MBA from the Schulich School of Business at York University; and his PhD in Operations research from the University of Waterloo. Professor Zhang has published many papers in prestigious journals such as Management Science, Operations Research, Manufacturing & Service Operations Management, Production and Operations Management, IIE Transactions, IEEE Transactions, Queueing Systems, Journal of Applied Probability. Co-authored with Professor Tian in 2006, he published the research monograph "Vacation Queueing Models - Theory and Applications," the first book on this particular topic (now highly cited). Professor Zhang's research interests include queueing theory and applications and stochastic models for manufacturing and service systems. The main theme of his research is to bridge the gap between theory and application, obtaining unobservable and sometimes counter-intuitive but significant/practical management insights via modeling and quantitative analysis. Currently, he is particularly interested in the quantitative and economic analysis of the congestion problems in urban/mass transportation networks, health/medical care systems, and public service systems with both customer service quality and security concerns. As an expert in data analysis and quantitative modeling, he has consulted in industry and has given research seminars and short lectures at leading universities around the world. He was invited to present plenary or keynote talks in several international conferences.Professor Zhang is the one of Editor-in-Chiefs for new journal Queueing Models and Service Management, aan associate editor of INFOR (Information Systems and Operations Research), and is on the editorial board of several international journals in Operations Research and Management Science.
