Laboratoire d'informatique de l'École polytechnique


The École polytechnique and CNRS are major participants of development initiatives in and around the Saclay plateau. It is therefore natural that LIX is part of a number of emerging scientific and technological initiatives based on the plateau.


Le LIX entretient des relations très étroites et actives avec Inria. En particulier, plusieurs des équipes du LIX sont des EPCs (Équipes-projets communs) Inria : Comète, Parsifal, Crypto (Grace) et Amib. En outre, depuis septembre 2012, le LIX occupe le bâtiment Alan Turing, qui est en copropriété avec Inria.

The Labex Digicosme

The Labex DigiCosme is an Excellence Laboratory (LabEx) built by the Scientific Cooperation Federation of Paris-Saclay. It is a proposition issued by the STIC community of the Saclay Plateau. DigiCosme is distinct from the Digiteo RTRA in two principal aspects: the Labex is more aimed scienfically along three axes (SciLex, ComEx, and DataSense), and performs net investments in education. These tree axes are:

  • SciLex: security and semantics
  • ComEx: networks and telecommunication
  • DataSense: data and visualisation

The Digiteo RTRA

The Digiteo RTRA is an STIC cluster covering the scientific domains of theory, design, development, and verification of software systems. It is a scientific cooperation federation created by the primary players in this domain on the Saclay plateau, including the École polytechnique, CNRS, and Inria.

Université Paris-Saclay

The collection of establishments and laboratories on the Saclay plateau (including LIX) are participants in the creation of the Université Paris-Saclay. It is an ambitious project, which aims to construct, with the cooperation of 23 partners, a university that can rival the largest and most prestigious worldwide universities.

In addition to LIX's participation in this construction at the level of the lab, many members of LIX participate in different working groups, such as a group for the construction of the Doctoral School in STIC or in the Department of STIC. Two members of LIX are elected to its Academic Council.

The "Systematic" Centre

The Systematic Centre groups a large number of industrial partners (PME/PMI and large enterprises) et and establishments of research and training in the Île-de-France region. The objective of this Competitivity Centre is to galvanize economic activity around digital technologies.

The Carnot Institute "Telecom and Digital Society"

LIX is part of the Carnot Institute "Telecom and Digital Society" (télécom et société numérique). This institute is composed of 31 research laboratories distributed throughout France.
