The Inria Saclay – Île-de-France research centre is a major part of the highly diversified ecosystem at Saclay which features leading partners in computational sciences. Research bodies, leading schools, competitiveness clusters and industry comprise the three complementary facets of research, training and innovation. A coordination program launched in 2000 took concrete form with the establishment of the Digiteo advanced research network. Most of our research teams are pooled with several institutions as proof of the strong links we enjoy with our partners. Centre researchers contribute to education for the students in Saclay. Training through research extends the approach with many doctoral students welcomed in research teams.
