Professor at the University of Lille (FSSEP) and member of the Unité de recherche pluridisciplinaire Sport, Santé, Société (URePSSS - EA 7369), I am interested in the links between life sciences and the humanities and social sciences in the study of social organizations and human movement. Our approach is based on a historical and epistemological perspective on the dynamics of innovation and creativity, exploring their evolution and implications. The question of “meaning” is central to our work, at the crossroads of practices, values and meanings attributed to transformations in the body and society.
