Professional experience :

  • 2000-2005 : research and PhD in COGIT
  • since 2003 : responsible for « networks » topic of the Research Action dedicted to applications of geographic data bases

Technical and scientific contributions :

The goal of my PhD work is to determine the aspects of the networks screen explaining their vulnerability (the screen being the « map» of the network, that is to say ways superposition and as a result all the relational links between entities). As an example, when there is an incident at the subway station Opera, is the subway network disturbed because there are many people who pass to this place? Or because the network is badly configured at this place? Both? Concerning this point, I am interested particularly in network configuration and its impact on vulnerability.
For these problems, the PhD results give several keys :

  • the definition of structural vulnerability of a network,
  • the evaluation of this vulnerability through the temporal penalties induced by local damages,
  • understanding of this vulnerability through indicators which evaluate the part plays by the components of the network during a normal period, and indicators which qualify the components capacity of being avoided in the route or of helping the other components of the networkin case of damages.
