4,000 researchers work in Rennes, mainly in the sectors of information and communication technologies.
In the IT sector, the Rennes area enjoys a high potential for research, both through specialist centres and in universities and leading engineering colleges. In Brittany, 56 public laboratories (30 in Rennes) employing 2,600 staff (2,000 in Rennes) are involved in research into new technologies in the electronics, computing and telecom sectors.
These research centres and laboratories provide companies with a means of optimising the know-how acquired through applied research and developing new techniques and products.
Rennes Atalante boasts three major public research units.
Inria Rennes – Bretagne Atlantique concentrates its research on large-scale distributed systems and the Internet of the future, reliable, efficient software and imaging and its applications. These areas are associated with significant work in transfer and innovation.
Irisa (Institut de recherche en informatique et systèmes aléatoires, Computer and random systems research institute) has a staff drawn from University of Rennes 1, CNRS, Insa de Rennes and ENS Cachan – Brittany campus. The work ranges from research into applications for networks and distributed systems, software and hardware, digital signals and imaging and data, knowledge and interaction.
Numerous research teams from Irisa and Inria Rennes – Bretagne Atlantique are common to both establishments. Together, they account for almost 600 people in Rennes, divided into some thirty research teams.
As a CNRS-associate laboratory, IETR (Institut d’électronique et de télécommunications de Rennes, Electronics and telecommunications institute) federates teams from the University of Rennes 1, Insa and Supélec. Its 280 researchers and Ph.D students are involved mainly in the design of new communication systems, antennae, microelectronics, radar propagation systems and the issues of embedded images and remote sensing.
