Headshot of professor Roger Dougal


Professor Dougal leads the Power and Energy Systems research group, where research principally focuses on power electronics but it also encompasses a wide range of associated technologies across a number of engineering departments. Dr. Dougal is a member of the Board of Directors of the Electric Ship Research and Development Consortium (ESRDC), and in that capacity he oversees USC's activities related to new power generation, processing, and distribution technologies for ships, and coordination of those activities with other member schools. Prof. Dougal is also Site Director of the new NSF-sponsored Industry/University Cooperative Research Center for Grid-connected Advanced Power Electronic Systems (GRAPES). This joint project between USC and the University of Arkansas seeks to insert greater levels of advanced power electronics into the utility power grid to better realize a Smart Grid. Since 1996, under sponsorship of the Office of Naval Research, Prof Dougal has overseen development of the Virtual Test Bed software, which is a comprehensive simulation and virtual prototyping environment for multidisciplinary dynamic systems. This environment is applied in studies of electric systems for navy ships, electrochemical power sources, hybrid power sources, power electronics, and controls.
Dr. Dougal currently supervises about a dozen graduate students, several post-doctoral scholars and research faculty, and a number of undergraduate researchers.
