CEA Saclay: cutting-edge, multidisciplinary research South of Paris

Located South of Paris, CEA Saclay is one of the ten CEA centers. It is a prominent player in European research and innovation. 6,000 international researchers work there in a great variety of fields such as astrophysics and neuroimaging.

An international, multidisciplinary scientific community

With around 6,000 researchers and collaborators, CEA Saclay covers many of CEA civil activities: low-carbon energies, climate and environment, physical sciences, defense and security, health technologies and technological research. It also plays a prominent role in the design and construction of very large research infrastructures. Researchers, scientists and students from over 70 countries work in the Saclay center as part of national and international research projects.

At the heart of the "Plateau de Saclay" scientific cluster

CEA Saclay is located south of Paris, on the Saclay shelf or "Plateau de Saclay", a unique area in France as it gathers a great number of researchers. The Saclay center takes part in the 2014 "Paris-Saclay University" project. Many CEA Saclay laboratories and institutes work in partnerships with universities and industries, and take part in international scientific projects, especially within the European Framework programme.

Cutting-edge, multidisciplinary research

Physical Sciences Research includes astrophysics, the study of the atomic nucleus, elementary particles and fundamental interactions. It also involves research on the properties of matter, carried out using complex infrastructures: Orphée reactor, lasers, nuclear magnetic resonance... CEA Saclay also focuses on climate dynamics and on modelling the impacts of greenhouse effect on the environment.

Applied research in the field of nuclear studies aims at maximizing the security of the French nuclear power plants as well as developing future reactors. Researchers at CEA Saclay focus particularly on the modelling of physical phenomena, chemistry, materials and the development of simulation and associated software applications.

Life Sciences Research focuses on the effect of radiation on cells and molecules, protein engineering, medical imaging and radioimmunoassay. Neurospin, a research department dedicated to neuroimaging, is part of the CEA Saclay campus.


Technological Research on Smart digital systems focuses on topics at the heart of today’s economy and society, such as embedded systems, interactive systems, sensors and signal processing. R&D activities are carried out as part of industry partnerships in the fields of transports, energy, safety and health.
