21 institutes of the Leibniz Association cooperate in the Leibniz Research Alliance Healthy Ageing. In addition, there are associated members from renowned research institutions in Germany and abroad. In interdisciplinary projects, they research the biological and social aspects of ageing. The interdisciplinary approach, which is unique in the German research landscape in this form, makes it possible to analyse the interactions between biological-medical and socio-economic aspects. The aim is to develop new adaptation strategies that promote healthy ageing in the long term. Biomedical scientists, educational researchers, spatial planners and economists work together in interdiciplinary teams.
