I study Scheduling Time Petri Nets as introduced by Roux and Déplanche: this extension consists in mapping into the Petri net model the way the different schedulers of the system activate or suspend the tasks (stopwatches). I work on an extension (based on polyhedral computation) of the classical state class graph for this model.

Study of a new type of data-structure adapted to the computation of the state class graph of a T-Time Petri Net with discrete semantics. We currently seek to extend the state class graph method to time Petri nets with inhibitor arcs (and hyperarcs) with a discrete time approach. This work is based on the research of the real-time systems team about extensions of BDD (Binary Decision Diagrams), e.g. VDD (Vector Decision Diagram).

I work with:

• Didier Lime
• Jean-Pierre Elloy, my PhD adviser
• Guillaume Gardey
• Olivier (H.) Roux, co-adviser
• Pierre Molinaro, co-adviser

During 2005-06, I am co-adviser (with Olivier (H.) Roux) of Charlotte Seidner's Master thesis. This work aims to propose a structural translation (that preserves behavioural semantics, i.e. timed bisimilarity) from a high-level architecture description language to Time Petri Nets.

Member of the program committee of RJCITR05.

I am involved in the development of Romeo, a software studio for Time Petri Net analysis: Romeo performs analysis on T-Time Petri nets and on one of their extension to scheduling. It is composed of a GUI (written in Tcl/Tk) and of two modules (written in C++) for computing the state space.

Romeo is a free software, distributed under GPL License, for Windows, Linux and MacOS X platforms.

I teach at the Mathematics and Informatics Department of the engineering school Ecole Centrale de Nantes. I supervise courses, directed works and lab works in:

I am very interested in all studies about the use of new concepts like weblogs, wiki, syndication, social networks, ... I have a personal weblog (in french) since 2001.

• In 2003, I was involved in a project for determining how weblogs and syndication could be used in the context of an engineering school.
• In 2004, I supervised a project led by two students from Ecole Centrale Nantes about the wiki concept and its possible applications in an universitary framework.
• In 2005, I initiated and led personnaly a project that aimed to install a SPIP publishing system on the collaborative learning environment of Centrale Nantes. I worked with Guillaume Moreau, Teaching and Learning Information Technologies manager.
  In september 05, the official release of Central'Info (this new publishing SPIP platform) came with an electronic tutorial to Linux I wrote. I'm in charge of the animation of Central'Info.
• In 2006, I have been invited to talk at the 5th CRITE workshop about my work on Central'Info. This workshop focused on the various ways teachers and professors may create interactive courses with the help of different kinds of collaborators.
