Stefano Olla 2007

Stefano Olla (born December 27, 1959 ) is an Italian mathematician who deals with stochastics and statistical mechanics.

Olla studied physics from 1978 at the University of Cagliari with a diploma (Laurea) in 1982. Then he was a Sloan Fellow at Rutgers University , where he received his doctorate in 1987 with Joel Lebowitz (Large Deviation Problems in Statistical Mechanics). As a post-doctoral student he was at the Courant Institute in New York and from 1989 at the University of Rome II. In 1992 he became an assistant professor at the Polytechnic in Turin (for probability theory) and was Maitre de Recherche at the École Polytechnique in 1994/95 . From 1996 to 2002 he was professor at the University of Cergy-Pontoise and at the same time professeur chargé de cours at the École Polytechnique from 1996 to 2008. In 2002 he became a professor at the University of Paris-Dauphine .

He examined fluctuations, large deviations and hydrodynamic limit values ​​in stochastic processes and microscopic models of heat conduction, for example in coupled systems of harmonic and anharmonic oscillators (also with disturbances and noise) and microscopic models of thermodynamic transformations.

He was on the editorial board of the Annals of Probability from 2009 to 2015 and of the Annales de l'Institut Henri Poincaré (Probabilité et Statistique) from 1994 to 2006 and is on the editorial board of the Journal of Statistical Physics, as was the case from 2002 to 2008, and of Probability Theory and Related Fields.

In 2010 he received an ERC Advanced Grant.
