Philippe is enrolled in a PhD program in international law at the Institute of Higher International Studies (Paris 2 Panthéon-Assas University) under the supervision of Associate Professor Martin-Bidou.
After obtaining his master’s degree at Sorbonne University and working within two international criminal tribunals, he started his PhD program on Sudan in 2012. Philippe carried out a two-years doctoral fieldwork in this country and benefited from a long-term doctoral scholarship from the CEDEJ research Centre (CNRS) in Khartoum. He is a guest researcher at the Law & Anthropology Department within the Max Planck Institute for Social anthropology (Halle-Saale) until April 2017.
His Ph.D. research is entitled Legal Orders in Motion: Sudanese customary Laws in International Peacebuilding. In this project, he tries to apply legal pluralism to international legal theory so as to investigate the international legal status of what he names ‘customary legal orders’. Relying on a formalist approach of international law, he offers a critique of cultural legal studies, which he perceives as a beacon to underplay the legal agency of these particular legal orders. He argues that legal formalism, rather than American realism, can allow for a methodology based on subaltern studies (Gramsci, 2011 ) freed from the dichotomist opposition of ‘colonialism versus post-colonialism’. This effort circumvents cultural approaches to legal pluralism that eventually convey reductionism or essentialism and prevent acknowledging customary orders for what they truly are: other legal orders with full access to the international legal system.
Philippe’s expertise includes public international law, human rights and humanitarian law, international criminal law, theory & philosophy of law, sociology of law, and legal pluralism. He is a member of the Andromaque-Sudan Project (ANR – CJB) related to The Anthropology of Law in African and Asian Muslim Worlds: The Sudan. He published two articles, a report, and more articles are currently under review or in writing.
