Reinoud Leenders provides policy advice and carries out research assignments for foreign ministries, governmental institutions, INGOs, law enforcement agencies, law firms and private companies active in the Middle East, especially in Syria and Lebanon. Recent such consultancies included research for the Dutch Police’s international investigative crime unit regarding matters related to war crimes and crimes against humanity involving Syrian nationals. Leenders provides expert witness testimonies, often based on elaborate research reports, to courts prosecuting Syrian nationals for ‘terrorism’ and war crimes and for international private companies and law firms involved in commercial dispute settlement mechanisms. Leenders also regularly advises law firms representing Syrian, Lebanese and Palestinian asylum-seekers. Leenders’ research assignments are carefully prepared, scrutinised and double-checked for accuracy and reliability, based on thorough investigations, and drawing on a wide range of sources in Arabic and, where needed, four other languages, and consulting a dense network of contacts within and beyond the Middle East.
