The Laboratory of Social dynamics and spatial reconstruction (LADYSS) is a multidisciplinary UMR (Mixed Research Unit) located in 4 university sites (Paris 1, Paris 7, Paris 8, and Paris 10). Associated with two Institutes of CNRS (National Centre of Scientific Research), the Institute of Human and Social Sciences (INSHS) and the Institute of Ecology and the Environment (INEE), Ladyss is dependent on two sections of CNRS (39 and 36) and 3 sections of CNU (National University Centre) (19, 23 and 24).

LADYSS’ project has four main research axes.

- Socio-spatial recomposition in globalization

- Everyday territories : representations, practices and projects

- Environment and development : towards a new paradigm ?

- Health issues and territories

The research teams in charge of these four axes are located at different sites and also have links to a number of different doctoral schools. These diverse links are a big plus for LADYSS’ project and represent both disciplinary and institutional diversity that make it way more than just a collection of individuals. It is precisely this diversity that helps forge scientific cohesion. The transverse approach "Science-society relationships through field tests" has been devised to create a high point during the year in terms of a collective dynamic.
