Ruben Tuitel completed his Master of Science in Crisis and Security Management at Leiden University in 2015. His master thesis focused on foreign fighters who appear in YouTube videos, telling something about their lives and experiences in Syria. By answering three basic questions – who are they, why do they go and what will they do next – he and his project partner discovered new insights about foreign fighters. In 2014, Ruben graduated from Safety and Security Management Studies at The Hague University of Applied Sciences, obtaining a bachelor in Public Management. He is interested in terrorism and counter-terrorism, foreign fighters and cyber security and likes to collect vinyl records.
