Présentation

My research focuses on sea ice physics, variability and forecast. I also look at the interactions between sea ice and the other components of the climate system, with a particular interest in the Arctic region. I have expertise in both sea ice modelling and observations statistical analysis, as well as some experience in data assimilation. Recently, I have been involved in the use of AI-driven approaches for solving diverse sea ice problems.More specifically, I worked on the multi-scale characterization of sea ice and earth crust dynamics, and how it can be translated in terms of continuous rheological models. This work materialized into the development of a new class of rheology for continuous sea ice models based on damage mechanics. In parallel, I investigated issues related to the remote sensing of sea ice drift, deformation, age, thickness and lead fraction from satellites. I also contributed to the development of a new framework for data assimilation into Lagrangian models running on adaptive meshes, in collaboration with data assimilation experts and mathematicians.I instigated and led the development of the next generation Lagrangian sea ice model neXtSIM and its associated operational forecasting platform neXtSIM-F until 2021. This platform provides sea ice information in near-real time for the Arctic region through the EU Copernicus Marine Environment Monitoring Service. Since 2021, I am the lead-PI of the SASIP project, an international collaborative effort to better understand the impact of amplified warming in polar regions, through the development of a new sea ice modelling paradigm. One noticeable deliverable of this project is to provide a new, truly innovative, scale-aware sea ice model; one that faithfully represents sea ice dynamics and thermodynamics and that is physically sound, data-adaptive, highly parallelized and computationally efficient. This model is designed to be used in next generation Earth System Models and forecasting platforms.
