Operations, Information & Technology

Our focus in the operations, information, and technology area is on the management of systems, processes, and networks.

Examples include health care systems, product design and manufacturing processes, supply networks, information systems, energy and environmental systems, homeland security systems, and social networks. We employ methods from the fields of operations research, game theory, econometrics, computer science, probability and statistics, and exploit the growing availability of data.
