Associate Professor

Associate Professor Jennifer K. Ryan holds a B.A. in Mathematics and the Social Sciences from Dartmouth College and an M.S. and Ph.D. from the Department of Industrial Engineering and Management Sciences at Northwestern University. Prior to joining RPI, she served as a faculty member in the School of Business at the University College of Dublin (Ireland), the Mendoza College of Business at the University of Notre Dame and in the School of Industrial Engineering at Purdue University. Her research interests are in the areas of inventory and supply chain management with a particular focus on coping with uncertainty and the role of information and information sharing in supply chains. Her research has been published in Management Science, Operations Research, Production and Operations Management, Naval Research Logistics and IIE Transactions. She has received several National Science Foundation (USA) grants, including an NSF CAREER grant. She currently served as an associate editor for Naval Research Logistics, IIE Transactions and OMEGA. Dr. Ryan has taught a wide variety of courses at the undergraduate, graduate and executive levels, in both engineering and business environments, including supply chain management, operations management, probability and statistics, decision theory and engineering economics.
