Juliette Galonnier is Assistant Professor at CERI, Sciences Po. She teaches a large course on "Religion, Politics, Society" and a seminar on "Islam in Europe and North America" at the Bachelor’s level.

She also teaches Qualitative Methods for both Bachelor students and Master students at the School of Research. She co-leads the Writing seminar for CERI's PhD students.

Her research investigates the social construction of racial and religious categories, and how they frequently intersect. Empirically, her work has been mostly focusing on Muslim minorities across various national contexts (India, France, the United States). She received in 2017 a joint PhD degree in Sociology from Sciences Po and Northwestern University. Entitled Choosing Faith and Facing Race: Converting to Islam in France and the United States, her dissertation was awarded the Best Dissertation Award of the American Sociological Association (ASA) in 2018. Building on 82 in-depth interviews and ethnographic observations in mosques and convert associations, this research provides a comparative analysis of the experiences of Muslim converts on the two sides of the Atlantic.

She has co-edited two books in French Religion and Social Class (ENS Editions, 2023) and Politics of deradicalization (Presses de Sciences Po, 2022). She has also published several chapters in edited volumes and articles in peer-reviewed journals such as Genèses, French politics, culture and society, Identities, Sociology of Religion, Social Compass, Archives de sciences sociales des religions, Critique internationale, Hommes & Migrations and Tracés.

From 2017 to 2019, she worked as a post-doctoral researcher within the "Global Race" ANR project. In 2018, she coordinated with Pr. Mahamet Timéra a research project on Muslims of Sub-Saharan and Comorian descent in France, funded by the Religions Office of the French Ministry of the Interior. From 2022 to 2024, she is co-coordinating a research project on "Religion and migration: French Caribbeans in the Hexagon".

She is also a fellow at IC Migrations, a member of Critique Internationale’s editorial board, a member of the ANR project "Islamic socializations", a member of the program "Agenda for a critical sociology of religion" and a member of the research network "Race, religion, secularism".
