About Sarah M. Ryan

Dr. Sarah M. Ryan’s research examines the planning and operation of manufacturing and service systems under uncertainty. Currently, she is focusing on electric power systems and closed loop supply chains with remanufacturing. Issues under study by her research group include long term expansion planning of bulk power systems, short term power system scheduling to accommodate renewable generation, and design of closed loop supply chains for uncertain environmental regulations. Her work has been supported by the National Science Foundation, including a CAREER award, an AT&T Industrial Ecology Faculty Fellowship, the Department of Energy, and electric power systems consortia.
