The Scientific and Strategic Council

This Committee, chaired by Prof. Gourraud, allows us to take a step back from our strategic and scientific choices. It also allows us to make our decisions in consultation or by vote if necessary. This is a major contribution and facilitates contacts and reflections in the framework of strategic decisions (patent, international opening...).
