March 2014: 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.

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.

April 2013: Max Potters awarded for his Master thesis

Max Potters, from Utrecht university, worked with me during one year in 2011 in order to prepare his Master thesis. He has been awarded a price for his work while in Lyon. His work deals with the statistical mechanics of the Shallow Water equations. It has been recognized as the best Master thesis of Utrecht university that year. More.

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".

I also advice you to look at the excellent seminar of Ray Pierre-Humbert on the history of the successes (and sometimes failures) of climate science to predict facts that have been observed a-posteriori. Pierre-Humbert's talk and slides.

September 2012: Book of Cedric Villani.

Publication of the book of the field medal recipient Cédric Villani: Théorème vivant, Paris, Éd. Grasset et Fasquelle, 2012.

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. 

June 2012: Organization of a conference on rare events in Lyon.

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:
COMPUTATION OF TRANSITION TRAJECTORIES AND RARE EVENTS IN NON-EQUILIBRIUM SYSTEMS (Applications in turbulence, chemistry, (bio)physics).
This event has been organized by Frédéric Cérou, Marianne Corvellec, Arnaud Guyader, Hugo Touchette and myself, with the help of Samantha Barendson.


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:
