He teaches Southeast Asia-Oceania prehistory at MNHN Master, Paris 1 and Paris 10 Nanterre University, and he is the PhD & Master advisor of several students in that field. In order to understand the global prehistoric peopling from Southeast Asia to near Oceania through the technology of knapped stone he has led numerous research projects, excavations and scientific cooperation, notably in Cambodia (team leader of the Mission Prehistorique Franco-Cambodgienne since 2009), Thailand, China, Laos, Indonesia and recently in Papua New-Guinea
