Davide Faranda

External Fellow

I started working in the theory of dynamical systems and its geophysical applications during my master thesis in Bologna in 2010. The development of dynamic indicators at the numerical and theoretical level has become my PhD thesis subject and the core of my research. My PhD project took place in three different countries (Reading – England, Hamburg – Germany, École Polytechnique – France), in contact with communities of climatologists (V. Lucarini, my thesis director), physicists (P. Manneville) and mathematicians (S. Vaiti, T. Kuna). These interactions have given a very interdisciplinary character to my PhD work. I completed my manuscript entitled: “Extreme value theory for geophysical Flows” after two and a half years of thesis.

My experience in France began in 2013 as part of a postdoctoral fellowship at CNRS under the supervision of B. Dubrulle and F. Daviaud at SPEC – CEA Saclay. My work focused on understanding the phenomena associated with intermittency in turbulent laboratory flows through the von Karman experiment. Thanks to those theoretical and numerical developments, I have extended the tools to interdisciplinary applications in financial data for the definition of precursors of crises. In 2014, I started a second post-doctoral contract as part of an ERC climate project led by P Yiou at LSCE. During this project, I have developed methods to study the recurrences of atmospheric weather regimes, particularly during extreme events (heat waves, cold waves, extratropical storms).

The interdisciplinary training that I acquired during these first phases of my career allowed me to build a solid project for the CNRS, which I joined in 2015. Since my hiring, my activity has been part of the LSCE ESTIMR team. My research activity mainly focuses on the definition of digital tools to study extreme weather events, using statistical physics methods. The universality of these methods allows me to continue the collaboration with the SPEC and the study of turbulent flows, and to apply them to different fields such as Epidemiology and Earthquake dynamics.

My international collaborations are part of this interdisciplinary research work: S. Vaienti (dynamical systems, CPT – Marseille), Y. Sato (dynamical systems and stochastic processes, Hokkaido University, Japan), N. Vercauteren (atmospheric turbulence, FU Berlin , Germany), G. Messori (climate dynamics, Stockholm, Sweden). Within CEA Saclay, I am involved in the organization of a Climat-Meca-Stat working group which links the skills of LSCE and SPEC while being enriched by the presence of other laboratories. My activity was recently recognized with the EGU Division Outstanding Early Career Scientists Award from the European Union of Geophysics.  Since 2017 I am research fellow of the London Mathematical Laboratory (London UK) and since 2019 external fellow of the LMD-ENS Paris.

My Research

have supervised 3 Postdoctoral researchers, 10 master students and 2 PhD students. I have published over 70 articles, with more than 1000 citations in 7 years (source google Scholar). I am currently PI of an ANR-TERC research project BOREAS (120 KEUR period: 2020-2022), and participant in several national and international projects. I am PI of the outreach project ClimarisQ, an Android/IOS game to understand the complexity of the climate systems.
