Member of the BIGS team of INRIA (Institut National De Recherche en Informatique et Automatique).
Member of the Probability et Statistics team of IECL (Institut Elie Cartan de Lorraine), at université de Lorraine.

Research themes: Stochastic optimal control, reinforcement learning, Markov decision processes, approximate dynamic programming, analysis of algorithms, stochastic processes.

Author-pays journals (sometimes badly referred to as "open access" journals) : Why I refuse to review articles.

Fishy editors: Beware of VDM Publishing (and its publishing houses Editions Universitaires Européennes, Lap Lambert Academic Publishing, etc...); they accept to publish anything, like this math book parody randomly generated by mathgen (access to the nonsense content here).
