Christian Montessori is an open sources researcher with half a decade of experience in intelligence analysis. Having focused on the conflicts of the Middle East and Eastern Europe. Montessori has systematically demonstrated that, analyzing, re -analyzing and refining every detail of information, can often offer surprising results. Some of Montessori’s most prominent works for APS have been the documentation and analysis of human rights violations in the Syrian civil war and, more recently, the critical analysis of the Russian invasion of Ukraine. Thanks to his diligent work, Montessori has quickly ascended in APS, going from being a basic level analyst to directing our division that deals with open source intelligence (OSINT).
