I am a CNRS (permanent) Researcher at the LSCE laboratory of the University of Paris-Saclay, in the ESTIMR group. Since September 2017, I am also external fellow of the London Mathematical Laboratory, London, United Kingdom
Extreme Value Theory
Classical Extreme value laws have been recently found for orbits of dynamical systems. The theory has been devised for a special class of observables which allow for a link between the concept of extremes and the lack of Poincare recurrences around a chosen point of the phase space. My contributions in this fields of research are directed towards the understanding of the relation between the recurrences and the extreme events , the nite time behavior of asymptotic laws [1,2,4,5] and the generalizations of theoretical aspects to physically meaningful systems [6,8,10,11,13,18].
The understanding of the mechanism regulating the transitions between di erent attracting states in complex systems is a general problem in statistical mechanics. Systems which feature such transitions range from spin glasses up to climate systems, ecosystems and finance . I have been involved in developing rigorous statistical methods for detecting the transition thresholds in datasets [3,12,17] and in the modeling of systems at bifurcation points via the so called ARMA (Auto Regressive Moving Average) processes technique .
Turbulent and Geophysical flows
Providing a statistical description of turbulence, by combining theoretical findings with high quality experimental datasets, is helping in understanding several features of turbulent flows as the dissipation anomaly or the existence of singularities in the Navier Stokes equations . I am actually contributing to this research field by developing statistical techniques based on the Extreme Value Theory and the ARMA process analysis which allows for quantify the distance between observations and theoretical models in a rich model-parameter space .
