LRI (Laboratoire de Recherche en Informatique) is the Laboratory for Computer Science at Université Paris-Sud, joint with CNRS, the National Center for Scientific Research. Founded more than 30 years ago, LRI has now over 260 members, including 115 faculty and staff and 110 Ph.D. students. LRI consists of twelve research groups, supported by an administrative and a technical staff. Eight of the twelve research groups are joint with INRIA Saclay - Ile-de-France, making it the main partner of the laboratory. The laboratory is located mainly in building 490 of the Orsay campus of Université Paris-Sud and will be located soon inside the PCRI's building. Some of the joint groups with INRIA are located at Parc Club, next to the Campus.

LRI is a partner in Digiteo, one of the twleve research networks created by the French government in 2006 and the only one in computer science. Digiteo gathers 1200 researchers from six national research institutions (CEA, CNRS, Ecole Polytechnique, INRIA, Supelec, Université Paris-Sud) and owns now three new members: Ecole Centrale Paris, ENS Cachan and Université de Versailles Saint Quentin en Yvelines. LRI is also a partner in System@tic Paris-Region, a competitiveness cluster with more than 200 industrial, academic and institutional members in the area of complex software and systems.

The research themes addressed by LRI cover a wide spectrum of computer science ranging from fundamental to applied research: algorithms, complexity, quantum computing, graph theory, combinatorial optimization, clusters and grids, software engineering, programming, human-computer interaction, databases, inference systems, data mining, machine learning, bioinformatics, etc. Such diversity is one of the strengths of the laboratory, fostering research at the boundaries across areas, where the potential for innovation is highest.

The laboratory participates in a large number of national and international projects, including those funded by ANR, the French National Research Agency and by the European Union. LRI members participate in many editorial boards of international journals and program committees of international conferences. The laboratory is also highly productive, with over 200 major publications per year.

This web site has been designed to help you better lear about LRI by presenting its activities along three main axes : research themes, collaborations, and research results. I hope you will enjoy navigating through this web site !
