Pritam Ranjan

ritam joined the OM&QT group at IIM Indore in June 2015. Before joining IIM, he was an associate professor in the department of Mathematics and Statistics at Acadia University, Nova Scotia, Canada. He obtained B.Stat. and M.Stat. degrees from the Indian Statistical Institute, Kolkata, and a Ph.D. degree in statistics from Simon Fraser University, BC, Canada.

His research areas include design and analysis of computer experiments, statistical models for computer simulators, sequential designs for feature estimation, and a projective geometric approach for multi-stage fractional factorial designs with randomization restrictions.
