The Laboratory

In few words

The LISN was created on January 1st, 2021; it is the result of the merger of the teams of two eminent computer science laboratories of University Paris-Saclay: the Computer Science Laboratory for Mechanics and Engineering Sciences (LIMSI) and the Computer Science Research Laboratory (LRI).

Administratively, LISN is a Mixed Research Unit (UMR) whose main supervisors are the CNRS and University Paris-Saclay, and whose secondary supervisors are INRIA and CentraleSupélec.


Its management team is composed of the director, Sophie Rosset, the deputy directors Didier Lucor and Michel Beaudouin-Lafon and the administrator.

Advisory bodies: the Laboratory Council, the Executive Board and the Scientific Council


400 people, including 180 researchers and teacher-researchers, 54 engineers and technicians, 145 doctoral students and more than 200 trainees trained each year and guest researchers.

The ambition of the Interdisciplinary Computer Sciences Laboratory is not only to contribute to the advancement of knowledge, but also to respond to the multiple societal challenges of the National Research Strategy (NRS).

Clean, secure and efficient energy and sustainable transport and urban systems

The main application areas of the Fluid Mechanics-Energy department are energy efficiency (Challenge 2, Clean, Secure and Efficient Energy) and the design of safer and less resource-intensive transportation (Challenge 6, Sustainable Urban Transportation and Systems).

Information and communication society

The other departments are mainly involved in Challenge 7 (Communication and Information Societywhose four orientations are covered: Data Science, Language Science and Technology, Algorithms, Learning and Computation all deal with the automated processing of large amounts of data; the department Data Science also deals with fifth generation networks and connected objects; the department Interaction with the Human is studying the design of collaborative interfaces between humans and machines.

Health and well-being & innovative, integrative and adaptive societies

The issues of processing masses of data are also present in Challenge 4 Health and well-being for bio informatics ( Data Science ) and bio-medical NLP ( Sciences and Language Technologies ), and in the Challenge 8 Innovative, integrative and adaptive societies for knowledge extraction, as well as in the Big Data action program ( Data Science ).

In addition to the National Research Strategy, LISN addresses other themes that respond to important societal issues, such as aiding learning and knowledge acquisition, assisting the elderly or disabled, protecting privacy, or the sovereignty of computing and data infrastructures.

Research Departments

Support and assistance to research

The support and assistance to Research departments bring together transverse functions to ensure the smooth running of the laboratory.
