Presentation of LIX Laboratory, UMR 7161 X-CNRS


Located in the heart of the research center on the Palaiseau campus of Ecole Polytechnique, LIX ("Laboratoire d'Informatique de l'X", UMR X-CNRS) has a hundred members of which half are PhD students and forty are permanent researchers, equally distributed between CNRS, INRIA, and the Ecole Polytechnique.

The activities of LIX are organized into three areas: algorithmic, networks, and formal methods.

Among the ten teams housed within the lab, six are INRIA projects that have been with LIX since the creation of PCRI (Common Pole of Research in Computer Science) on the Saclay plateau. A joint team between LIX and LIST at the Atomic Energy Commission has existed prior to the establishment of the RTRA Digiteo that promotes the co-location of its various teams.
LIX also hosts the Chair in "Complex Industrial Systems" financed by Thalès. Since LIX collects such a number of projects, the lab has become an essential academic actor in the System@tic Pole of Competitiveness.

LIX has a particular interest in developing competence in the multiple facets of network communications, ranging from the treatment of signals, the coding and routing of communications, the distribution and mobility of computation, and the safety and engineering of protocols.

Since mobile networks will be a central component of the future world of embedded systems, lab members have put a particular stress on the development of reliable and effective communication systems in mobile networks.

The lab is heavily involved in teaching at Ecole Polytechnique and at several MASTER programs in the Paris area. LIX has various contractual relationships with public organizations (Ministry of Higher Education and of Research, Directorate General of Armaments, the French Agency for Innovation, INRIA, etc) and with several international organizations.

During the last years, LIX sought to develop collaborations with the industrial world. In addition to Thales, LIX has also established connections with Microsoft Research, Hitachi Labs, and NASA.

The Director,

Philippe Baptiste
