Dionysios obtained his PhD from Purdue University in 2003, and his Diploma in ECE from the National Technical University of Athens, Greece, in 1999. Prof. Aliprantis’ teaching and research interests are related to electromechanical energy conversion, with emphasis on electric machinery (their modeling, simulation, and design), power electronics (particularly machine drives), applications of automatic control to power electronics-based systems, and the analysis of power systems. More recently his work has focused on technologies that enable the integration of renewable energy sources in the electric power system, and the electrification of transportation.
