Dr. Alexandra “Sascha” von Meier is Co-Director for Electric Grid Research at the California Institute for Energy and Environment (http://uc-ciee.org), and Adjunct Associate Professor in the Department of Electrical Engineering at UC Berkeley. She is currently studying technical and operational issues related to the integration of high levels of renewable resources in “smart grids,” in particular, increasing the visibility on power distribution circuits through advanced instrumentation. Her past research has addressed engineering and cultural dimensions of energy technology, including electric power distribution, grid-connected photovoltaics, electric demand response, nuclear power plant operation, nuclear materials management, and green buildingperformance. Her textbook, Electric Power Systems: A Conceptual Introduction (Wiley-IEEE, 2006), has been used in university courses and industry to help explain the complexities of operating the electric grid, and she regularly presents tutorials on electric power delivery to academic and professional audiences. Sascha received her Ph.D. in energy and resources (1995) and her B.A. in physics (1986) from the University of California, Berkeley. Away from the office, she enjoys cycling, rock climbing and the mountains whenever possible.
