From our beginnings as a merger of three existing departments—Operations Research, Industrial Engineering-Engineering Management, and Engineering-Economic Systems—we have become one of the most respected Management Science and Engineering departments in the world. The department’s mission is, through education and research, to advance the design, management, operation, and interaction of technological, economic, and social systems. The department’s engineering research strength is integrated with its educational program at the undergraduate, master’s, and doctoral levels: graduates of the program are trained as engineers and future leaders in technology, policy, and industry. Research and teaching activities are complemented by an outreach program that encourages the transfer of ideas to the environment of Silicon Valley and beyond.
