The Nantes Digital Sciences Laboratory (LS2N)

What The Nantes Digital Sciences Laboratory (LS2N) does

LS2N (Laboratoire des Sciences du Numérique de Nantes) is a French public research laboratory classified as a Unité Mixte de Recherche (UMR 6004), created in January 2017 through the merger of IRCCyN and LINA. It is jointly tutored by CNRS, Nantes Université, Centrale Nantes, and IMT Atlantique, with Inria as a research partner through joint project-teams. The lab is the largest public research unit in Nantes and the Pays de la Loire region, employing 500+ people across five campus sites — 245 permanent staff (researchers, teacher-researchers, administrative/technical), 180 doctoral students, and 72 engineers and postdocs — organized into 22 research teams spanning five scientific poles (CCS, RPC, SDD, SIEL, SLS) and six transverse themes covering industry, energy, health, mobility, digital cultures, and education.

LS2N's core outputs are open-source research software and specialized platforms developed by its 22 teams. The software portfolio includes Coq (proof assistant), CHOCO (Java constraint programming library), IBEX and GAOL (C++ interval computation libraries), Trampoline V3.0 (OSEK/VDX and AUTOSAR-compatible real-time operating system), SaGe (SPARQL query engine with Web preemption), PILGRIM (Bayesian network learning), TermSuite (terminology extraction), NeoEMF and EMF Views (EMF modeling framework and Eclipse plugin), pke (keyphrase extraction), PyLFIT (Boolean network learning), ARACHNIS (cable-driven robot design), and several VR/signal processing tools (Revistim-X, SimScene, Algo-RIM, Procurve). The lab also operates 22 specialized research platforms including driving simulators, autonomous vehicles, robotic labs, virtual reality, smart factories, additive manufacturing, bio-inspired robotics, aerial robotics, and parallel robotics facilities.

As a public research laboratory, LS2N has no commercial revenue model. It is funded by French public institutions (CNRS, Nantes Université, Centrale Nantes, IMT Atlantique, Inria) with additional research grants and Investments for the Future program participation (IRT Jules Verne, b<>com, Labex CominLabs, Robotex). Industry partnerships include CHU de Nantes for medical imaging and health research. Research outputs are distributed through HAL open archives, scientific publications, seminars, conferences, and thesis defenses, targeting the academic research community in digital sciences including robotics, artificial intelligence, signal processing, software engineering, and distributed systems.

Core offering

The Nantes Digital Sciences Laboratory (LS2N) is an academic research organization focused on digital sciences. The specific products, services, and operational details are not supported by the provided source material.

Product overview

The Nantes Digital Sciences Laboratory (LS2N) is a research laboratory (Unité Mixte de Recherche UMR 6004), not a commercial product company. It does not offer commercial products or services for sale. Instead, LS2N conducts fundamental and applied research in digital sciences across 22 research teams organized into 5 scientific poles. The laboratory produces research software tools developed by its research teams, including proof assistants (Coq), constraint programming libraries (CHOCO), SPARQL query engines (SaGe), real-time operating systems (Trampoline), keyphrase extraction toolkits (pke), terminology extraction tools (TermSuite), and various specialized software for robotics, bioinformatics, signal processing, and virtual reality applications. These are open-source research outputs rather than commercial product offerings.
