Simon Van Hoeymissen has a multidisciplinary background: in 2012, he obtained his master’s degree in criminology from the KU Leuven and, in 2013, he graduated from the Vrije Universiteit Brussel (VUB) in political science. In both disciplines, he specialised in international security matters, with a specific focus on EU-Russian dynamics.

After graduating, he worked in the private sector, both abroad and at home, which enabled him to become acquainted with the world of think tanks and to develop the necessary language skills (English, Dutch, French, German and Danish). Since 2020, he has been part of think tank Eleni.

In September 2020, he embarked on his platoon commander training at the Belgian Defence. At the end of 2021, he returned to civilian life and attended a policy innovation training course at the London School of Economics and Political Science. Following the Russian invasion in Ukraine, he worked during four months in an emergency village for Ukrainian refugees in Belgium until he rejoined Defence in January 2023 as a researcher at the Centre for Security and Defence Studies (CSDS).
