A transversal approach is required by the development of interdisciplinary research, especially at the interface between experimental, social and human sciences. However this approach remains insufficient and minimizes citizens’ concern about these challenges. We show in this paper that Participatory Action Research allows us to develop original research methods if it can work in hybrid stable forums. These spaces allow us to meet and to work with stakeholders of a research project (researchers, non-profit organization members, practitioners, etc.) in the medium or long term. Such a forum was created in 2013 as a formal research group of the CNRS named Participatory Action Research and Citizen Sciences (GDR CNRS PARCS). This forum is like a research laboratory without walls. We describe our experiences led in this laboratory, the impact on the members due to the development of training and the positive conclusions that we can obtain for the development of such approaches.}}
