Teaching Activities
I have been teaching for thirty years, first mathematics at school and then computer science in various universities. I have had many different kinds of classes : children, adults, literary and scientific students. I also participated in seminars for engineers.
On the undergraduate level, my teaching activities have been mostly devoted to algo-rithmics and programming languages, computer organization and operating systems, and foundations of computer science. I also teached stochastic processes for performance eva-luation and distributed computing.
Two textbooks for undergraduate courses are related to these topics : an introduction to operating systems [LI-1], with J. Beauquier, and [LI-2] on the verification of concurrent systems, with A. Arnold, J. Beauquier and B. Rozoy.
Research tutoring
• Masters Degrees
I tutored the work of D. Ambroise on Interprocess communication with wait-free
ato-mic varoiables (PhD Univ. Paris Sud 2001).
With Ph. Schnoebelen, I co-tutored A. Labroue (ENS de Cachan), on Liveness
condi-tions in timed automata and M. Ben Ga¨ıd (Univ. Paris Sud) on Time properties of PLCs.
With P. Bouyer, I co-tutored A. Robin on Extending decidability for region graphs.
• PhD
With Ph. Schnoebelen, I further co-tutored A. Labroue [CI-10], on Process algebra
for infinite system verification, PhD defended in 2002. She is now teaching at Univ.
With F. Laroussinie, I co-tutored H. Bel Mokadem on Verification of timed
proper-ties for PLCs, PhD defended in 2006. She is now assistant professor in ENSA Tanger
(Morocco).
I was advisor of Mathieu Sassolas (Digiteo CoChaT with LSV) on Information
hi-ding. He defended his PhD on November 28th, 2011, and begins next January a
post-doctoral position with Jean-Fran¸cois Raskin in Universit´e Libre de Bruxelles. I am currently advisor of Yan Zhang (Chinese Scholarship Council grant) on
Auto-mated transport systems.
