General Information

Dr. Lee’s research lies within the disciplines of applied probability (service operations, stochastic networks, stochastic control) and statistics (sequential learning, inference for stochastic processes), but also crosses the boundaries between the two toward developing analytical tools that will facilitate the use of the extensive operational data available nowadays to improve large-scale service operations, production systems and retailers. He has collaborated actively with researchers in several other disciplines of engineering (communication networks, financial engineering), biology (population dynamics) and epidemiology (infectious disease control).
