Morteza Nazari-Heris, Ph.D., is an Assistant Professor of Electrical Engineering at the Department of Engineering at East Carolina University. Before that, he worked as an Assistant Professor of Electrical Energy Systems with the College of Engineering at Lawrence Technological University and as a Graduate Research Assistant with the Department of Architectural Engineering at Pennsylvania State University, where he earned his Ph.D. specializing in energy systems. During his graduate studies, he worked on projects for the future, flexible, equitable, and robust networks of charging stations for high adoption of electric vehicles, application of machine learning and deep learning methods to energy systems, and sustainable design of buildings with renewable energy sources and energy storage facilities. Dr. Nazari-Heris obtained his BSc and MSc in electrical engineering from the University of Tabriz. His main areas of interest are energy system operation, energy management, sustainability, zero-energy Buildings, electric vehicles, microgrids, multi-carrier energy systems, and energy storage technologies. He has received several awards and fellowships, including three Outstanding Thesis Awards. He serves as an editor and reviewer for several journals and conferences. He is an active member of several professional communities, including the IEEE, the Clean Energy Leadership Institute (CELI), and Young Professionals in Energy.Sasan Azad is a Ph.D. student in the Department of Electrical Engineering and a researcher at the Electrical Networks Institute of the Shahid Beheshti University. He obtained his BSc degree from the Razi University of Kermanshah and his MSc from the Shahid Beheshti University. His main areas of interest are power system security and voltage stability, smart grids, and electric vehicles.
