Jennifer Bidet, associate professor at the Université Paris-Descartes, uses an intersectional approach to study immigration. She has worked on the dynamics of social mobility in migration, analyzed through the prism of family relations between France and Algeria in a transnational perspective. Experienced in the ethnography of relations within (Algerian) immigrant families, J. Bidet will manage the qualitative investigation of the 3GEN project.

Louise Caron is a tenured researcher at INED and a fellow at the IC Migrations.

Pauline Clech is a post-doctoral researcher at INED, on the 3GEN project (qualitative part). Her research focuses on atypical forms of social mobility, which take place outside of school and school certification. She has explored this process through three empirical fieldworks: cultural institutions in the communist suburbs (PhD), summer camps (post-doctorate), and the ethnic entrepreneurship of families from Palestinian and Syrian immigration in Chile (post-doctorate). Her research investigates the role of discrimination and racial assignment in these upward trajectories.

Margot Delon is a tenured researcher at CNRS (University of Nantes). Her research interests include urban sociology and the study of socioeconomic and racial inequalities. She has conducted research on the comparative analysis of the social trajectories of the Portuguese and Algerian children who grew up in the French shantytowns in the 1960s. She is currently investigating the topic of rental property in France and in Italy.

Lucas Drouhot is an Assistant Professor at Utrecht University. Previously a Postdoctoral Research Fellow at the Max Planck Institute for the Study of Religious and Ethnic Diversity, he obtained a PhD in sociology in 2018 from Cornell University.

Mathieu Ferry is a postdoctoral researcher at INED on the 3GEN project. He obtained a PhD in sociology in 2021 from the Institut d’Etudes Politiques de Paris.

He is particularly interested in the links between so-called "ascriptive" positions - such as ethnicity - and the processes of "status group" formation. He uses both quantitative and qualitative methods in the study of Indian and French societies.
