Guillaume Teillet

Guillaume Teillet is an Associate Professor in Sociology at the University of Nantes, affiliated with the UFR Sociology department. He researches juvenile justice, working-class fragmentation, and institutional regulation of youth deviance through the Nantes Center for Sociology (CENS) and GRESCO. His PhD (2019, University of Poitiers) analyzed judicial constraints on working-class youth.

Research Focus: Teillet's work intersects sociology of law, education, and social stratification. Key themes include:

• Social differentiation in juvenile justice systems
• Ethnographic studies of penal pathways
• Institutional labeling of disability/delinquency
• Working-class family dynamics under judicial pressure

Publications: His 15 most recent works (2015–2025) show consistent focus on youth trajectories within judicial frameworks, using mixed methods to expose systemic biases. Studies like the 2025 analysis of ASE/PJJ 'double follow-ups' reveal how institutions reproduce social inequalities.

Affiliations & Labs: Teillet collaborates with GRESCO (Poitiers/Limoges) and CENS, advancing sociological studies on contemporary justice systems and policy impacts.
