Lieutenant Colonel Sideris Kyratsoudis serves in the Hellenic Army and is currently stationed as a Plans Officer at the Support Division in Thessaloniki. He graduated with honors from the Hellenic Army Academy in 2004. He also holds a degree in Chemical Engineering from the Aristotle University of Thessaloniki (A.U.Th.), where he graduated with honors in 2013, followed by a master's degree in Materials Science. Additionally, he earned a degree in Economics with a specialization in macro- and microeconomics from A.U.Th. in 2019, and a distinguished postgraduate degree in "Networks and Complexity" (M.Sc.) in 2021. Lt. Col. Kyratsoudis is actively engaged in research for his Ph.D. at the Democritus University of Thrace (DUTH), focusing on the application of multi-criteria decision-making (MCDM) methods using entropy-based tools for military decision-making processes. His previous academic work in this field, conducted at A.U.Th., involved the optimization of military logistics and supply chains through advanced process optimization techniques. Fluent in seven languages, he has presented his research at various academic conferences, notably through the Hellenic Mathematical Society. His research interests include mathematical modeling, game theory, network analysis, and decision-making optimization in complex operational environments, with a strong focus on applying these methodologies within military and defense contexts
