{{Short description|French mathematical physicist}} 200px|thumb|Pierre Collet, 2016 '''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''.<ref>{{MathGenealogy|id=99745}}</ref> Collet is currently Director of Research of the CNRS at the École polytechnique.<ref>[https://www.cpht.polytechnique.fr/?q=en/node/84 Pierre Collet, CPHT, École Polytechnique]</ref>

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.<ref>{{cite book|author=Collet, P.|chapter=Extended dynamical systems|title=Doc. Math. (Bielefeld) Extra Vol. ICM Berlin, 1998, vol. III|year=1998|pages=123–132|chapter-url=https://www.elibm.org/ft/10011570000}}</ref>

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
