Between emergence, institutionalization and reassessment, gender and sexuality studies have continued to mutate, transform and question the humanities and social sciences in the last decades. These developments have provoked reactions, criticism and resistance both inside and outside the academic arena. Gender studies, as much as gender itself, is on the move. For its twentieth anniversary, the “Atelier Genre(s) et Sexualité(s)” (AGS) research center at the Université Libre de Bruxelles intends to promote Belgian research in gender and sexuality studies, and reflect on recent developments, at an interdisciplinary colloquium to be held in Brussels from December 15 to 16, 2025. By taking a retrospective look and presenting future prospects for research in this field, this colloquium will put into dialogue papers by young researchers from French- and Dutch-speaking Belgian universities with established researchers who have passed through the AGS. This bilingual French-English colloquium will examine current research on gender and sexuality through five main themes presented below and a round-table. Each panel will be chaired and discussed by an actual or former member of the AGS.
