Erol Peköz has a BS degree from Cornell University, and MS and Ph.D degrees in Operations Research from University of California, Berkeley. Working in the areas of applied probability and statistics, Professor Peköz studies probability approximations surrounding rare events for stochastic models, queueing models for congestion and statistical models for health care provider profiling. His work appears in academic journals such as Annals of Probability, Annals of Applied Probability, Statistics in Medicine, Bernoulli, Journal of Applied Probability and Medical Care. He has conducted research funded by the Department of Health and Human Services, Agency for Healthcare Research and Quality, the Robert Wood Johnson Foundation, and the Veterans Health Administration. He has also worked as a consultant for Pfizer and the Accenture Institute for High Performance Business. Professor Peköz has also taught on the faculty at Harvard, UCLA and also at UC Berkeley, where he received an award for outstanding instruction. At Boston University he was awarded the Broderick Prize for Teaching.
