About

S. Ali Khajehoddin received his Ph.D. degree in electrical engineering from Queens University, Kingston, ON, Canada, in 2010. He is currently a Senior UofA Engineering Research Chair in Energy Systems and a Professor at the University of Alberta, Edmonton, AB. Prior to his Ph.D., he had co-founded a start-up company that was focused on the development and production of power analyzers and smart metering products for smart grid applications. For the doctoral research with Queen’s University, he concentrated on the design and implementation of compact and durable microinverters for photovoltaic (PV) grid connected systems; leading to the spin-off of SPARQ Systems Inc., where he worked as the Lead R&D Engineer toward mass production and commercialization of microinverters from 2010 to 2013.  His current research interests include design and implementation of high-power density power converters based on novel modeling techniques, topologies, and controllers for energy systems. Dr. Khajehoddin was the recipient of several awards including Second Place Paper Award from IEEE Transactions on Power Electronics in 2022. He is also an Associate Editor for IEEE Transactions on Power Electronics, IEEE Transactions on Transportation Electrification, and IEEE Journal of Emerging and Selected Topics in Power Electronics.
