Biography

Professor Dougal retired in 2023 but continues to participate in research activities related to modeling, design, and operation of naval power systems. Prior to retirement, he led the Power and Energy Systems research group, where his research principally focused on power electronics but also encompassed a wide range of associated technologies across a number of engineering departments. Dr. Dougal was a member of the Board of Directors of the Electric Ship Research and Development Consortium (ESRDC). Prof. Dougal was Site Director of the NSF-sponsored Industry/University Cooperative Research Center for Grid-connected Advanced Power Electronic Systems (GRAPES). For many years, under sponsorship of the US Office of Naval Research, Prof Dougal has developed software for analysis and design of multidomain power and energy systems, including the dynamic systems simulator Virtual Test Bed, and software such as S3D for analysis of power and energy flows during concept design of ships.
