Biography

I'm senior researcher (Directeur de Recherche) at Inria and the scientific leader of COATI, a joint project-team between the research center of Inria Sophia Antipolis - Méditerranée and the I3S laboratory which itself belongs to the CNRS and the University Nice - Sophia Antipolis (UNS). I received a Master degree in Computer Science from ENS Lyon and UCBL in 1997, a PhD in Computer Science from UNS in 2001, and the Habilitation à Diriger des Recherches in 2010. I did a post-doc in 2002 at Universitat Polytècnica de Catalunya (UPC), DMA4, Barcelona, Spain. In September 2002, I became Chargé de Recherche at Inria Sophia Antipolis. I was a member of the joint project-team Mascotte between INRIA and the I3S laboratory(CNRS/UNS) till December 2012. I was team vice-leader of Mascotte from July 2006 till March 2011, and then the scientific leader of the team till December 2012. In January 2013, we started the new joint project-team COATI. In 2016, I have been promoted Directeur de Recherche.

Research interest:
  • Algorithmics, combinatorial optimization, graph theory
  • Algorithm engineering
  • WDM networks: traffic grooming, routing and wavelength assignment, protection, reconfiguration
  • Wireless Backhaul networks: design, configuration, routing
  • Design of fault tolerant networks: shared risk resource groups and various kind of protection mechanisms
  • Transportation networks: routing, planning, multi-modal

I'm an active contributor of the open source project Sagemath and in particular of its graph module (tickets written and reviewed).

This summer, I was a mentor for Sagemath in the context of Google Summer of Code. The students, Rajat Mittal, Georgios Giapitzakis Tzintanos, and Ritesh K have worked on improving various methods of the graph module related to shortest paths computation and implementing Yen's k-shortest simple paths algorithm. They have also implemented various graph traversal methods like Lex-BFS, Lex-DFS, Lex-UP, Lex-DOWN, and Lew-M. See the tickets on which the students have worked. Project reports can be found on students web pages.
