The CNRS/ University of Strasbourg Laboratory SAGE (Societies, Actors and Governement in Europe), was created on January 1, 2013. As a result of the merger between  four research teams : GSPE (Centre for European Political Sociology) ; CRESS (Centre for Study and Research in the Social Sciences) ; LESVS, Laboratory of Sociology and History of Biological Sciences and Medecine ; CDES (Centre for Environmental Law).

SAGE is composed of 10 CNRS researchers, 54 Professors and Senior Lecturers, 5 research engineers and technician and 68 PhD candidates.Marine de la Salle Professor of Political Science is director and Philippe Cordazzo, Professor of Demographics is deputy director.

This pluridisciplinary team brings together researchers working on transnationalisation processes, and in particular European construction as a response to globalisation, as well as the transformations and political and social dynamics linked to these processes. In this perspective, emphasis is placed on the sociology of transnational actors who elaborate and implement new norms and policies having effects on new social issues (environment, health, ageing, social vulnerabilities, culture, urban areas, etc.) and on the territorial dimensions of these dynamics.

Research in SAGE places an emphasis on empirical fieldwork as a means to test theoretically constructed hypotheses. Methodology seeks to triangulate data through the mobilisation of quantitative and qualitative social science methodology (archives, ethnographic observation, statistical analysis) allowing for an integrated pluridisciplinarity around common research themes.

SAGE is a laboratory centred on the social sciences of politics with an original approach to important social and political issues such as health, environmental law and policy, urban sustainable development, social and cultural policies, the internationalisation and circulations of elites, the political sociology of Europe and social movements. Research is structured around 6 internal work groups, working in close collaboration and on a project oriented basis.
