Short Biography

I am a Professor at the University of Rennes holding the Inria Research Chair on Energy-Efficient Computing Systems. I am leading the Cairn team common to Inria (French research institute dedicated to computational sciences) and IRISA Laboratory. Until 2019, I was also the head of the “Computer Architecture” department of IRISA. From 2012 to 2017, I was on secondment at INRIA as a Senior Research Director. My research interests are in the area of computer architectures, embedded systems and signal processing, with a focus on system-level design, energy-efficiency, reconfigurable systems, hardware acceleration, approximate computing, fault tolerance, and power management of energy harvesting sensor networks. I authored or co-authored more than 250 journal or conference papers, hold 6 patents, and served in the technical committees of several international IEEE/ACM/IFIP conferences, among which DATE, ICCAD, FPL, ENSSys, SBCCI, VLSI-SoC, Reconfig, NewCAS, VTC, ISCAS, ISQED.

As we have many in the French Academic system… below a tentative explanation.

Irisa (Institut de Recherche en Informatique et Systèmes Aléatoires – Research Institute in Computer Science and Random Systems) is a joint research laboratory (UMR 6074) gathering more than 700 people (faculty members, PhD students, PostDoc, engineers, administrative and technical staff) from InriaCNRS, University of Rennes 1 (main partner), INSA Rennes and ENS Rennes.

Enssat (graduate engineering school in applied science and technologies) is a graduate engineering school of Univ. Rennes 1 located in Lannion.

Inria is the French science and technology research institute (3500 researchers) fully dedicated to computational sciences. Inria Rennes – Bretagne Atlantique is one of its eight research centers.

Cairn is the research group I lead (~50 people). The team is common to Irisa and Inria and includes (Nov. 2012): 13 faculty members from UR1, Inria, and CNRS; 28 PhD students; 5 Post-Docs; 8 research engineers; 3 associated members.

The scientific aim of Cairn is to study reconfigurable system-on-chip, i.e. hardware systems whose configuration may change before or even during execution, from three angles: the invention of new reconfigurable platforms, the development of associated compilation and synthesis tools, and the exploration of the interaction between algorithms and architectures.
