The French Alternative Energies and Atomic Energy Commission, or CEA (French: Commissariat à l'énergie atomique et aux énergies alternatives), is a French public government-funded research organisation in the areas of energy, defense and security, information technologies and health technologies. The CEA maintains a cross-disciplinary culture of engineers and researchers, building on the synergies between fundamental and technological research.
CEA is headed by a board headed by the general administrator (currently François Jacq since 20 April 2018), advised by the high-commissioner for atomic energy (currently Patrick Landais (fr)). Its yearly budget amounts to €5.8 billion and its permanent staff is slightly over 21,000 persons.
