Guillaume Teillet

Guillaume Teillet serves as a Lecturer in Sociology at the National Higher Institute of Teaching and Education (INSPÉ) of the University of Poitiers, based at the Niort site. Affiliated with the GRESCO Laboratory (EA3815), his academic work bridges teacher education and sociological research on justice systems, with an institutional email at guillaume.teillet@univ-poitiers.fr.

Teillet completed his PhD in Sociology at the University of Poitiers in 2019 with the dissertation Une jeunesse populaire sous contrainte judiciaire (A working-class youth under judicial constraint), establishing his foundation in institutional ethnography of marginalized youth.

His research centers on the sociology of deviance and juvenile justice, with specialized focus on working-class youth trajectories, judicial selectivity, and the intersection of civil/criminal legal systems. Methodologically, he employs ethnographic fieldwork and questionnaire surveys to analyze social control mechanisms in educational and penal institutions, particularly examining how disability labels compound judicial marginalization.

Teillet's publication trends reveal sustained investigation into French youth justice systems since 2015, with recent work (2020-2025) increasingly addressing hybrid legal pathways and disability intersections. His scholarship consistently highlights structural inequalities in how working-class youth navigate institutional constraints, demonstrating methodological rigor through detailed case studies of judicial processing.

No scientific awards are documented in available sources.

As an academic advisor, Teillet supervises internships for the IPHD master's degree program, though specific student names remain unlisted. His service contributions include editorial duties for Societies and Youth in Difficulty (SEJED) and leadership in the French Sociology Association's Youth Thematic Network (RT15), reflecting active engagement in youth sociology communities.

Teillet operates within the GRESCO Laboratory's research ecosystem while contributing to national academic infrastructure through the RT15 network and SEJED journal. His collaborative projects, including the 2021 co-edited volume Les frontières du privé. Un travail du social, demonstrate integration into French sociological networks focused on institutional boundaries and social intervention.
