Biography

Dr. Julia Zhang received her Ph.D. degree in electrical engineering from The Ohio State University 2010. From 2010 to 2012, Dr. Zhang was a control engineer at Ford Motor Company, leading design and development of electric machine drive and power electronics control strategies and specifications for Ford’s 2013 hybrid electric vehicle products including Fusion Hybrid, Fusion Plug-in Hybrid, C-Max Hybrid and C-Max Plug-in Hybrid.

Dr. Zhang joined Oregon State University as an assistant professor in the fall of 2012. Her research interests include the design of high power density, high torque density AC electric machines for vehicle systems, robotic systems and renewable energy generation systems, modeling and control of AC electric machine drive systems, system noise, vibration and harness issues caused by electric machine drive components interaction and mitigation methods applying novel machine design and control strategies, and circuit, cooling and packaging design of various types of power converters for vehicle systems, robotic systems and renewable energy conversion systems. Dr. Zhang's research is currently funded by Ford Motor Company, the U.S. Office of Naval Research, the Grainger Center for Electric Machinery and Electromechanics, and the U.S. Department of Energy.
