Dr. Chanaka Edirisinghe joined the faculty in 1991. His teaching and research interests include stochastic programming, linear and nonlinear optimization, health care modeling, project management, and investment modeling and portfolio optimization.

Dr. Chanaka Edirisinghe is Professor and the Ph.D. Director of the Management Science program, and he has been with the program since 1991. He holds a BSc degree in Mechanical Engineering , M.Eng degree in Industrial Engineering and a PhD degree in Management Science from the University of British Columbia . His teaching interests include stochastic optimization, linear and nonlinear optimization, financial optimization and production/operations management .

His research interests are in stochastic programming approximations, with applications to multi period financial planning, production/allocation problems, and health-care management . His research articles appear in journals such as Operations Research, Mathematics of Operations Research, Mathematical Programming, Annals of Operations Research, Journal of Financial and Quantitative Analysis, and Water Resources Research . He also serves as a journal referee for Management Science, Operations Research, Mathematical Programming, Annals of Operations Research, Discrete Applied Mathematics, Computational Optimization and Applications, and Stochastic Models.

Dr. Edirisinghe serves as a consultant to the Frank Russell Company, Tacoma, WA, for developing and implementing large stochastic programming models for financial asset allocation. He is also a consultant to Market Research Inc., Bahamas, on developing models for futures trading. He is a member of the Institute for Operations Research and the Management Sciences (INFORMS), and Mathematical Programming Society.  Dr. Edirisinghe is the current Vice-Chair (stochastic programming) of the optimization section of INFORMS.
