The scientific departments of IRISA
(before Jan. 2022)
To go back to the current organization see the page
The 7 departments cover the whole range of IT topics from computer and network architecture to artificial intelligence, software engineering, distributed systems and virtual reality.
Large Scale Systems (D1)
LARGE SCALE SYSTEMS department addresses a variety of issues arising from large-scale computer systems featuring a large number of machines and/or users and/or data, typically in cloud, fog or IoT networks or in HPC.
Research activities in this broad topic focus on three main challenges: (i) dependability and security; (ii) performance, scalability and efficient resource management; (iii) understanding, easing the use and programmability.
CIDRE, EMSEC, SPICY, KERDATA, MYRIADS, WIDE
Networks, telecommunication and services (D2)
Implementation and evaluation of communication networks, adapted to the increasing heterogeneity of terminals, applications and interaction modes.
ADOPNET, CASA, DIONYSOS, EASE, OCIF
Development of architectures and compilation tools for multi and many core heterogeneous systems, for general purpose platforms or for embedded systems, taking into account the constraints of performance, real-time, consumption or limited resources.
GRANIT, PACAP, TARAN
Language and Software Engineering (D4)
The research agenda of D4 is to provide the scientific foundations and the accompanying technology for constructing safe, secure and efficient software and systems. The recent convergence between embedded software and cyber-physical systems also induces new challenges in terms of self-management and security, in addition to the traditional issues in efficiency and functional correctness. This results in two main line of work : model-based system/software engineering, and verification and machine-checked program analysis.
Main contributions : (i) Logical approaches to the verification of cyberphysical systems, (ii)Software engineering and system of systems modeling, (iii) Verifying and proving software safety, (iv) System modeling.
ARCHWARE, CELTIQUE, DIVERSE, HYCOMES, LOGICA, SUMO, TAMIS, TEA
Signal and Digital Images, Robotics (D5)
This department contributes research on the formalization, design and experimentation of models and algorithms to process, transmit and transform digital signals and data stemming from a variety of physical phenomena, with a focus on acoustic and audio signals, video and visual data, motion signals and captures, medical images, geoscience observations, and physical embodiment and interaction with the environment (robotics).
The main results concerns the following broad topics: (i) Advanced sensor-based control in robotics and shared control architectures, (ii) Machine learning, sparse modeling and compressive sensing, (iii)Optimal and uncertainty-aware sensing, (iv) Audio, signal and image processing.
EMPENN, OBELIX, PANAMA, RAINBOW, SIROCCO
Media and interactions (D6)This department focuses on one or more media or modalities, be it text (digital or handwritten), speech, sound, image or video. Research is devoted to the aspects of analysis, modeling, generation and usage. The objective is either to reproduce human behaviour or to allow interactions with data and documents that are relevant to humans.
To do this, we focus on four challenges and rely on an intensive use of technological platforms : (i) Synergies analysis/synthesis, (ii) Complexity processing and performance management, (iii) Human behavior, semantics and cognition, (iv) Uses and interactions, (v) Technological platforms.
EXPRESSION, HYBRID, INTUIDOC, LINKMEDIA, MIMETIC, PERCEPT
Data and Knowledge Management (D7)
Data processing and more specifically the exploration of the relationships between data and knowledge. At the heart of artificial intelligence, work focuses on the storage, querying and visualization of massive or complex data, as well as the exploitation and enhancement of this data.
DRUID, DYLISS, GENSCALE, LACODAM, SEMLIS, SHAMAN
