Pierre Collet

Pierre Collet (born 1948) is a French mathematical physicist, specializing in statistical mechanics, stochastic processes, and chaos theory.

In 1978, Collet received a doctorate under Jean-Pierre Eckmann at the University of Geneva, with a thesis entitled Étude du modèle hiérarchique par le groupe de renormalisation. Collet is currently Director of Research of the CNRS at the École polytechnique.

Collet is known for mathematically exact investigations of several model systems in statistical mechanics and chaos theory. He was an Invited Speaker of the ICM in 1998 in Berlin.

He is not to be confused with the University of Strasbourg's Pierre Collet, who specializes in artificial evolution and complex systems. https://cstb.icube.unistra.fr/index.php/Pierre_Collet
