My research focuses on supply chain network design in general and facility location models in particular. I currently am studying reliability in supply chain design as well as sustainability issues associated with supply chains. I am also studying problems in health care operations research with a current focus on transplantation. I have taught courses on: probability, statistics, operations research, supply chain reliability, location modeling, health care operations research, service operations management, and heuristic algorithms. Currently, I teach courses on service operations management for upper level undergraduates and MS students, a course on operations analysis and management (also for upper level undergraduates and MS students) and an introductory (sophomore level) course on operations management.
I hold the Clyde W. Johnson Collegiate Professorship in the Department of Industrial and Operations Engineering of the College of Engineering at the University of Michigan. I am a past-president of INFORMS, the Institute for Operations Research and the Management Sciences. I am also the former chair of the IE/MS Department at Northwestern University as well as a past editor-in-chief of IIE Transactions, the flagship journal of IIE, the Institute of Industrial Engineers. I am a past vice president of publications of INFORMS. Finally, I serve on a number of editorial boards and am a former editor-in-chief of Transportation Science. In 2017, I was elected to the National Academy of Engineering.
Prior to joining the faculty at the University of Michigan I held a Walter P. Murphy Professorship in the Department of Industrial Engineering and Management Sciences of the Robert R. McCormick School of Engineering and Applied Science at Northwestern University.
