Dr. Richard is interested in both the theoretical and computational aspects of Mixed-Integer Nonlinear Programming (MINLP). On the theoretical side, Dr. Richard develops new solution methods and algorithms. These advances are aimed at solving, in a reasonable amount of time, problems that are currently intractable. On the practical side, Dr. Richard uses these methods to obtain solutions to industrial problems, mostly in the area of transportation.

Dr. Richard teaches classes at the undergraduate, master’s and Ph.D. levels in the area of Operations Research and Mathematical Optimization. In particular, he has designed/taught classes in linear, nonlinear, stochastic, discrete and combinatorial optimization. He also has designed/taught courses in stochastic processes, simulation and decision making.  

Jean-Philippe P. Richard is a professor of the Department of Industrial and Systems Engineering (ISyE) at the University of Minnesota. Within the department, he is serving as Director of Faculty and Academic Affairs. Prior to joining the University, Jean-Philippe held academic positions at Purdue and more recently at the University of Florida where he was a UF term professor and Industrial and Systems Engineering PhD coordinator.   His research interests are in the theoretical and computational aspects of mathematical optimization (integer and mixed integer nonlinear programming). He is particularly interested in convexification methods and polyhedral approaches to these problems. He is also interested in the application of these techniques in data, medicine, transportation, and infrastructure protection.

Jean-Philippe has carried cooperative research with several Class I railroads.  His research has been funded by NSF, Union Pacific, and CSX. He is an associate editor for JOGO, IISE Transactions, Optimization Letters, and IMAMAN. He is the recipient of an NSF CAREER award, multiple teaching awards, and the best application paper award from IIE Transactions.
