The technological research division of the CEA (CEA Tech) brings together more than 4,000 researchers, engineers and technicians, and more than 500 doctoral students.
Positioned at an essential stage in the innovation chain, it works in close collaboration with numerous partners from industry and academic research, in France, in Europe and out of Europe. Each year, CEA Tech technologies allow the creation of 6 to 10 start-ups, several of which have become leading players in their field, at the global level.
On the Grenoble and Paris-Saclay sites, with the CEA-Leti, CEA-List and CEA-Liten Institutes, and in a set of smaller establishments in other French regions, CEA Tech creates a wide range of portfolio of technologies engaged with digital, energy and medical transitions.
When joining CEA Tech, our doctoral students are joining an adventure rooted in 50 years of history, and marked by scientific advances and innovations serving the major challenges of our societies.
