Johanna Mathieu is an associate professor of Electrical Engineering and Computer Science at the University of Michigan, Ann Arbor. Prior to joining Michigan, she was a postdoctoral researcher at ETH Zurich, Switzerland. She received her PhD and MS from the University of California at Berkeley and her SB in Ocean Engineering from MIT in 2004. She is the recipient of an NSF CAREER Award, the Ernest and Bettine Kuh Distinguished Faculty Award, and the UM Henry Russel Award. Her research focuses on ways to reduce the environmental impact, cost, and inefficiency of electric power systems via new operational and control strategies. She is particularly interested in developing new methods to actively engage distributed flexible resources such as energy storage, electric loads, and distributed renewable resources in power system operation, which are especially important in power systems with high penetrations of intermittent renewable energy resources such as wind and solar.
