The Climate and Statistical Mechanics group
at ENS de Lyon aims at
Studying climate dynamics phenomena, specifically related to turbulence, climate extremes, and large scale dynamics of atmospheres and oceans.
Developping algorithms aimed at computing rare events in complex dynamical systems, like climate dynamics or turbulent flows, based on large deviation theory and statistical mechanics.
Studying fundamental questions in statistical mechanics and dynamical systems theory, often using large deviation theory, bridging from mathematical physics to modeling and applications
Recent and forthcoming events we are
organizing or have organized:

AXA grant - Extreme events in climate
Jeroen Wouters, a young post-doc researcher, has been awarded a two year AXA fellowship in order to work under my supervision. We will work on the computation of the probability of extreme events in climate models. He is just arrived at ENS-Lyon.
February 2014: Lectures at
Slides lecture 1.
Slides lecture 2.
Slides lecture 3.
Warsaw school of statistical physics lecture notes
November 2013: ERC Grant.
I have been awarded a European
Research Council grant: "Large Deviations and Non
Equilibrium Phase Transitions for Turbulent Flows,
Climate, and the Solar System". The aim of the research
project is to use tools from statistical mechanics (large
deviation theory, algorithms to compute rare events) in
order to compute rare events relevant for climate, and the
solar system dynamics.
2013: Seminar in classes préparatoires.
February 2013: Large
audience conference in a UK High-School.
As I was fellow of the Institute of Advanced Studies of Warwick university (UK), at the mathematic department, I was asked to make a public lecture for high-school students at the grammar school of Stratfort-upon-Avon, the former school of Shakespeare. Slides.
Can we predict cyclones by rolling dices ?
December 2012: Invited seminar at AGU meeting, San Francisco.The American Geophysical Union meeting gathers the world specialists of geosciences. I gave an invited seminar on "atmosphere jet dynamics and statistical physics". Slides:
October 2012: Large audience seminar on climate, in Lyon: “Changements de climat : changements de société ?”, organisée par Pauline Lachapelle dans le cadre des recontres "Et si on en parlait"

Villani: Théorème vivant,
Paris, Éd. Grasset et Fasquelle, 2012.
September 2012: Book of Cedric Villani.
Cedric refers in his book to some relations
between his work and ours (please do not
laugh when you will see my picture in his book).
September 2012: Lectures of Peyresq's school published.
During four years, I was organizing a school on nonlinear dynamics, Aux Rencontres de Peyresq, in the village of Peyresq. Together with J.A. Sepulchre and B. Audoly, we have edited a book: Peyresq lectures on non-linear dynamics, with some of the main lectures. It has just been published.
2012: Organization of a conference
on rare events in Lyon.
May 2012: Antoine at CNRS.Antoine Venaille, my first PhD student, has been hired at CNRS after a two-year post-doc in Princeton in the Geophysical Fluid Dynamics In relation with my project to develop tools for the theory and computation of extreme events in turbulent flows with application to climate, I have initiated a conference that gathered the world specialist of rare event computation in natural sciences:
