Associate Professor of Operations & Manufacturing Management
My main research interests are in supply chain management, which primarily deals with how to match supply with demand. To achieve this goal, a firm needs to carefully manage both sides of the supply chain. The first part of my research focuses on how a firm should contract with upstream suppliers to ensure efficient and responsive supply, i.e., the supply side. The second part of my research is concerned with how to deal with strategic customer behavior that may affect a firm’s operational strategies, i.e., the demand side.

My earlier research focused on energy and environmental systems modeling and analysis. We have contributed to the development of the methodology of index decomposition analysis, which can be used to study factors affecting energy consumption and greenhouse gas emissions, and to monitor economy-wide energy efficiency trends. The decomposition techniques based on our research have been adopted by national energy agencies and international organizations, including Australia, Canada, New Zealand, the U.S., and the World Bank.
