Following the completion of his doctoral studies, he conducted postdoctoral research as a Research Fellow at the University of the Peloponnese, examining the impact of the refugee crisis on organised civil society in Greece. He has taught both undergraduate and postgraduate courses at the Department of Political Science and International Relations and has participated as a researcher, scientific associate and project coordinator in numerous national and European research projects.

For several years, he served as senior research associate at the Centre for Security Studies (KEMEA), contributing to the design, coordination and implementation of projects funded by Horizon Europe, Horizon 2020, the Internal Security Fund (ISF) and Erasmus+. His work focused on international security, prevention of radicalisation and violent extremism, organised crime, criminal justice and climate resilience. Throughout his career, he has collaborated with universities, research institutes, law enforcement authorities and public organisations across Europe, including the Hellenic Foundation for European and Foreign Policy (ELIAMEP), the National Technical University of Athens, the Climate Change Hub and other national and international institutions.

He also has extensive experience in the management of complex public-sector projects. Before joining the University of the Peloponnese, he served as Project Manager at the Strategy and Innovation Directorate of the Athens Water Supply and Sewerage Company (EYDAP), where he worked on strategic planning, innovation management, knowledge management and climate resilience, bridging academic research with evidence-based public policy and institutional innovation.

His research interests include diplomacy and international organization, theories and practice of international cooperation, international and environmental security, climate diplomacy and the geopolitics of the energy transition, European integration and governance, transboundary natural resource governance, as well as policies addressing radicalisation, violent extremism, organised crime and human trafficking.

His academic work seeks to bridge theoretical approaches in International Relations with applied research and public policy, contributing to interdisciplinary solutions for contemporary global and European challenges.
