Most of my research activities concern the algorithmic side of game theory and its applications in computer
science. At the moment, I am particularly interested in stochastic games with partial
I have proved several results about the existence of pure and stationary
optimal strategies in zero-sum stochastic games with perfect information
I have also worked on the approximability of parity games by multi-discounted
games and existence of Blackwell optimal strategies in these games
Beside their theoretical interests, these results have applications in
controller synthesis for discrete event systems and verification of programs.
A few years ago, I used to be interested in games played on transition graphs of pushdown
and I designed algorithms for solving parity and exploration games on this
kind of graphs .
These results provide new tools for the Model-Checking of programs with

About automatic numerical evaluation of research
Two convincing critics of automatic numerical evaluation of publications and researchers using impact factors, h-numbers and so on...
A technical one, in french, written by INRIA computer scientists.
Another one, "The Mismeasurement of Science" less technical and more acid, written by a Cambridge biologist.
The mitigated opinion of the french academy of science.
