François Jacob Institute of Biology
The IBFJ, located on the CEA-Paris-Saclay sites in Fontenay-aux-Roses, Evry, and Saint Louis Hospital, conducts research in radiobiology and radiotoxicology, neurodegenerative, infectious, and immuno-hematological diseases, and medical and environmental genomics.
Frédéric Joliot Institute of Life Sciences
The Frédéric Joliot Institute of Life Sciences (CEA-Joliot) studies the mechanisms of life to both produce knowledge and address societal challenges at the heart of the CEA's strategy: future health and medicine, digital technology, and energy transition.
Leti Institute
The CEA-Leti is a world leader in R&D in the field of microelectronics technologies. The institute designs, develops, and transfers safe and energy-efficient components and systems to its industrial partners.
List Institute
The CEA-List focuses its research on intelligent digital systems: artificial intelligence, factory of the future, cyber-physical systems, quantum computing, and digital health.
Liten Institute
The CEA-Liten is dedicated to the energy transition. It focuses its activities on solar energy, grid management, storage (batteries and hydrogen) with a logic of energy efficiency and circular economy.
Joint REsearch Units
A number of research activities are carried out within the framework of close academic partnerships with units shared between several partners, or joint research units (UMR). CEA hosts 38 of such units, among which:
Institute of Biosciences and Biotechnology of Aix-Marseille
(Joint Research Unit - Main UMR 7265. Supervisors: CEA, CNRS, Aix-Marseille University)
The BIAM studies the effects of environmental constraints on living organisms (plants, bacteria, microalgae), their adaptation, and their ability to produce high-value molecules. It also develops tools to detect and remediate toxic agents present in the environment.
Institute of Theoretical Physics
(Joint Research Unit - Main UMR 3681. Supervisors: CEA and CNRS)
The IPhT studies fundamental laws of the Universe at infinitely small (particle physics) or large (cosmology) scales, the physics of complex systems (statistical physics, condensed matter and quantum physics), as well as their underlying mathematical description.
Laboratory of Climate and Environmental Sciences
(Joint Research Unit - Main UMR 8212. Supervisors: CEA, CNRS, and University of Versailles-Saint-Quentin-en-Yvelines)
The LSCE's mission is to conduct research in the fields of measuring and understanding climate change and the impact of human activities on the global environment.
