Charaudeau Santomauro, Bastien

Bastien Charaudeau Santomauro is a French-Argentinian PhD candidate at Sciences Po Law School, a Fox International Fellow at Yale University, and a Fellow of the French Collaborative Institute on Migrations (ICM). His research articulates an interdisciplinary analysis (legal ethnography, doctrinal analysis and legal theory) of the legal processes of marginalization of migrants at the border. He works in particular on the case of the French-Italian border where he does his fieldwork. He seeks to unveil the legal operations that determine the status of migrants at the border. He examines more specifically how the dynamics of the socio-legal controversy around the border affect the interpretation and the elaboration of migration law, in particular migrants’ legal standing and citizens’ right to provide assistance to foreigners. Bastien is undertaking his research under the supervision of Pr. Jeremy Perelman (as principal supervisor), Pr. Loïc Azoulai and Pr. Julie Saada (as secondary supervisors).

Bastien is a graduate in Political Philosophy, Law and Migration Studies. He holds a B.A. in Humanities and Social Sciences (Sciences Po, 2013), an M.A. in Political and Legal Philosophy (Sorbonne University, 2015), an M.A. in Economic Law - Global Governance Studies (Sciences Po Law School, 2016) and an advanced M.A. in Interdisciplinary Analysis of the European Integration – Europe and Migrations (Institute for European Studies - University libre de Bruxelles, 2017). At the Sorbonne, he wrote his master’s thesis on normative and democratic challenges in the production of Labour Law through collective bargaining. At the Institute for European Studies, he defended his thesis on the impact of states of exception on migrant rights at the French-Italian border.

In 2018-2019, Bastien Charaudeau Santomauro was a visiting research scholar at Northeastern University School of Law (Boston, Massachusetts, U.S.). There, he pursued his research in close contact with the Institute for Global Law and Policy at Harvard Law School.

Bastien is part of the Law School’s Migration Clinic since 2019, where he initiated in 2019-2020 a clinical project that aimed to examine the controversial legal basis of migrant detention at the French Italian-Border. He is now a member of the Scientific Council and coordinates the Clinic’s program on Migrations.
