    A brief biography

    I received the Ph.D degree and the "Habilitation à diriger des recherches", both in Computer Science, from the University of Orsay (Paris XI), France, in 1989 and 1993, respectively. I am currently a research director at the performance evaluation group MISTRAL of the national research center on information and automation (INRIA), France. My current research interests are in control and performance analysis of high speed communication networks, scheduling and performance evaluation of parallel and distributed systems. I am also interested in Petri nets and queueing networks.

    One of my current activities consists in leading a project on the modeling and the characterization of Web traffic. We have been developing a software tool WAGON (Web trAffic GeneratOr and beNchmark) for generating Web traffic and for the performance evaluation of Web servers and cache.

    You are welcome to take a look at my list of publications to have a more general idea of my research activities.

    I have been teaching DEA (i.e. Frecnch graduate) courses of Operations Research, Networking and Parallel Computing for more than ten years. These courses are concerned with Queueing Theory, Probabilistic Modeling, Stochastic Scheduling and Quality of Service in Computer Networks. Currently I am involved in the DEA IRO (Informatique et Recherche Opérationnelle, i.e. Computer Science and Operations Research) of the University of Pierre & Marie Curie (Paris VI) and the DEA RSD (Réseaux et Systèmes Distribués, i.e. Computer Networks and Distributed Systems) of the University of Nice - Sophia Antipolis, France.

    I am currently supervising two Ph.D. students:

    My research interests

    are in
    control and performance analysis of high speed communication networks, scheduling and performance evaluation of parallel and distributed systems. I am also interested in queueing networks and Petri nets.

    As a particular application area, I'm interested in the analysis and optimization of the performance of Web servers and Web applications. You can take a look at the page on our activities related to the performance issues of the Web.

    We are maintaining a Web page on the literature related to the above mentioned fields. Any comments are welcome and can be mailed to Zhen Liu, Nicolas Niclausse and Cesar Jalpa.
