Eleftherios O. Kontis received the Dipl. (Eng.) and Ph.D. degrees in electrical engineering from the Department of Electrical and Computer Engineering, Aristotle University of Thessaloniki (AUTH), Thessaloniki, Greece, in 2013 and 2018, respectively. From 2018 until 2021, he conducted post-doc research, focusing on the real-time assessment of the stability and the dynamic analysis of modern power systems. During his Ph.D and post-doc studies, he was a scholar of the Greek State Scholarship Foundation. From 2021 until 2024 he worked at the Southeast Electricity Network Coordination Center, initially as a power system engineer and afterwards as director of the Business Development Department. Currently he collaborates, as an external consultant, with the Southeast Electricity Network Coordination Center, providing consultant services to issues related to power system security analysis and capacity calculation. He has ten years of experience as a researcher in EU Research Projects (FP7, H2020, and Interreg-Med). His main research interests include power system modeling and dynamic analysis, distributed generation, operation and control of active distribution networks, provision of ancillary services from distributed energy resources, and real-time analysis of power systems through field measurements.
