Saif Benjaafar is an internationally renowned leader in the field of operations management and supply chains. He has published ground breaking research that investigates how complex and global supply chains should be designed and managed. His work on sustainable supply chains introduced innovative ideas for reducing the environmental footprint of supply chains. His recent work on collaborative consumption is among the first to layout the foundation for the economic and environmental analysis of the sharing economy.
Benjaafar is currently Distinguished McKnight University Professor at the University of Minnesota. He is Head of the Department of Industrial and Systems Engineering and Director of the Initiative on the Sharing Economy, a university-wide initiative. He is also Professor of Industrial and Systems Engineering, Senior Faculty Scholar at the Center for Transportation Studies, and Fellow of the Institute on the Environment. He was the founding Head of Pillar (at the rank of Dean) for Engineering Systems and Design at Singapore University of Technology and Design (SUTD), a new university established in collaboration with MIT. He was also Founding Director of the Program in Industrial and Systems Engineering which he led through a transformation from a small graduate program into a full-fledged department.
He was a Distinguished Senior Visiting Scientist at Honeywell Laboratories and a Visiting Professor at universities in France, Belgium, Hong Kong, China and Singapore. He is the incoming Editor in Chief of the INFORMS journal Service Science.
His papers have been published in leading journals including Management Science, OR, and MSOM. His research has been funded by NSF, DOT, DHS, and DARPA in the US and by NRF and MOE in Singapore. His research work and teaching have been recognized by numerous awards, including the Harold Kuhn Award, the INFORMS Distinguished Service Award, the MSOM Best Paper Award, the George Taylor Distinguished Teaching Award, and the IIE Fellow Award, among others. He has consulted widely with leading companies and organizations such as Honeywell, General Mills, 3M, and the World Bank, among many others. He is a member of the Board of Directors of Hourcar, a social car sharing startup and served on Technology Advisory Board of the Keppel Corporation. His work was featured by major news outlets in the US, Asia, and Europe.
