A post-doctoral researcher at INSERM (Cermes3) within the ARCHE project funded by IRESP, Vincent Verroust works on psychedelic substances from a humanities and social sciences perspective. He defended a doctoral thesis (UPJV) on the heuristic implications of the discovery of hallucinogenic mushrooms in Mexico. Actively involved in shaping the field of psychedelic studies in France, he initiated the first French professional training program on psilocybin administration in medical research, participates in the training of psychotherapists interested in the medical use of serotonergic hallucinogens in Switzerland, and supports several French hospital teams in the implementation of therapeutic research with these substances.
