This re-organization appeared to us as necessary for carrying out our research program and for applying our strategy with our integration to the Paris Saclay University in view.  Among the advantages of this new organization is the better highlighting of our recent research advances in fields such as instrumentation and imagery systems or biomicrosystems, which were a bit in the shadow of our historical activities dealing with energy systems. The major research fields the SATIE is going to focus on are: the energy management, the clean transport, the ecosizing, the imaging and instrumentation systems, the protection of the environment and of the material heritage, and the life engineering.

For many researchers of the SATIE, the IDA has long appeared, up to a point, as a closed organization, the scientific prospects of which were far from theirs. However, an interdisciplinary organization such as the IDA must carefully watch over being widely open in order to prevent the risks of standardization of its scientific thought, which can lead to isolating it from the neighboring communities, such as the SATIE. To avoid such a risk, we need scientific regeneration channels drawing in the founding laboratories ecosystems. Only such a structural opening will ensure the scientific porosity expected in a long-term strategy for a real interdisciplinary innovation and the involvement of everyone. So for, it is necessary to clearly state i) the society challenge the IDA purpose represents, so that every of our scientists can get hold of it; and ii) the scientific opening upon which the latter is assumed to be built. I would say: let us trust in researchers, let them dream and let open the door to them. In this way one can make sure that they will come in..

Quite often, the research and education organizations which consider themselves as being interdisciplinary actually consist in the sum of disciplinary organizations. The IDA goes further because in addition to the disciplinary excellence of its researchers it has already carried out a scientific sedimentation enhancing the work at interfaces of different disciplines. The experience of the IDA on what could be named a method of scientific fertilization will be particularly welcome in the EOE department where it could play a useful structuring role. It could also strengthen the EOE department in its international influence regarding engineering of transdisciplinary systems.
