Roel studied English Language and Culture at Utrecht University (with minors in Conflict Studies and Journalism) and International Relations in Historical Perspective. He graduated with honours with a thesis on the Plantation Guard during the Indonesian War of Independence (1945-1950). In May 2017 he successfully defended his dissertation entitled, Collaboration is A Delicate Concept: Alliance-Formation and the Colonial Defence of Indonesia and Malaysia, 1945-1957 at the European University Institute in Florence, Italy. This thesis is a case study on the interface of late European empires and colonized societies. Specifically, it investigates how the Dutch and British empires sought to recruit local supporters in Indonesia and Malaysia, respectively, and how these locals negotiated decolonization for their own ends and interests.
