GeePs / SATIE

Laboratory Group of electrical engineering, Paris (GeePs)

The laboratory is a joint unit of CNRS, CentraleSupelec, Paris-Saclay University and Sorbonne University. Created in 2015, it is the result of the merger of the LGEP (Laboratoire de Génie Electrique de Paris, the original mixed unit) with part of the ex-Supélec host team and the L2E (Laboratoire d'Electronique et d'Electromagnétisme) host team from Sorbonne University. It is located on the CentraleSupélec campus of Paris-Saclay University in Gif-sur-Yvette and on the Pierre and Marie Curie campus of Sorbonne University in Paris.

 The research work carried out within the unit combines a triple approach: theory - numerical modelling - characterisation and experimental validation. They are divided into 3 poles that allow activities to be carried out on a continuum that extends from materials to systems, whether electronic or energy conversion. Two cross-disciplinary centres of expertise provide support. The first capitalises on the work related to the laboratory's historical competence in the numerical modelling of electromagnetic systems with an orientation towards multiphysical, coupled problems. The second brings together the laboratory's numerous experimental platforms with the primary objective of pooling skills in instrumentation and sharing know-how and resources.

Laboratory Systèmes et Applications des Technologies de l'Information et de l'Énergie (SATIE) 

The SATIE laboratory, initially created under the name of LESIR at ENS Cachan in 1984, is a research laboratory in applied sciences dedicated to information and energy technology systems and applications. It is a joint research unit of the CNRS (UMR 8029) and currently has a staff of about 200 people from the Ecole Normale Supérieure de Paris-Saclay (ENS PS), the Centre National de Recherche Scientifique (CNRS), the Conservatoire National des Arts et Métiers de Paris (CNAM), the University of Paris Seine Cergy-Pontoise (CYU), the University of Paris-Saclay and the Gustave Eiffel University. SATIE's scientific fields are Electrical Engineering and Applied Physics, Systems Physics and Biomicrosystems.

The general vocation of the laboratory is the study of complex systems combining information and energy. It carries out work in fundamental disciplines such as electrical engineering, physics, system physics and microsystems for the modelling, design and optimisation of an energy and/or information system. Its objective is to reconcile the expectations of society and the enrichment of knowledge. SATIE is organised around two poles that are almost equal in terms of the number of researchers and PhD students: CSEE (Components and Systems for Electrical Energy) and SIAME (Multi-scale Information and Analysis Systems). Research in SIAME is closely linked to that of CSEE because the problems of modelling, estimation, identification and detection are common to both information and energy systems.
