He has led this initiative since then, raising close to USD 2 million for its implementation. In addition to its academic outputs, the project has resulted in an international network of experts supporting ethnic peace-making around the world. In 2011, he launched a major international research activity in cooperation with the United Nations Secretariat relating to peace-making and peace agreements which has also attracted significant funding. Similarly, he is heading a major international project on transitions in international law, also conducted in cooperation with the United Nations.

In that role, he advised on the transitions in Cote d’Ivoire, Egypt, Yemen and Libya, on the Doha Peace Process for Darfur and on the stabilization of Somalia. Subsequently, he served as a legal advisor to the UN and League of Arab States Joint Special Envoy for Syria, Kofi Annan. He remains Senior Consultant to the UN Special Advisor on Yemen, Jamal Benomar and serves as Senior Mediation Expert for Lakhdar Brahimi, the Joint Special Representative of the UN Secretary-General for Syria..
