From June 12 to 15 Barbara Allen, professor of Science, Technology, and Society, conducted a seminar, “Introduction to Community-Based Participatory Research,” to introduce researchers to community-based participatory research for health. The four-day training event was hosted at the Institute for Advanced Study (IMéRA) in Marseille, France. Assisting Allen was the rest of the Fos “Etude participative en santé environnement ancrée localement” (Locality-based Participatory Environmental Health Survey) research team. The training was available at no cost to the 20 French researchers and public health officials who participated, thanks to support from the Agence nationale de sécurité sanitaire de l’alimentation, de l’environnement et du travail (Agency for Food, Environmental and Occupational Health).
