I am a Professor of Community Psychology at the University of Quebec. I have been working in the field of early childhood prevention for the last 15 years. In France, I have developed several public-orientated services of prevention (CAPEDP, PANJO, Petits pas Grands pas) which were the first interventions based on research ever led in the country. In Quebec and in France, I am involved in several research projects aiming to identify the facilitators for the success of public (governmental) preventative interventions. I am currently head of the “Epione: public health-community health” research team.
