Research

Mes activités de recherche portent sur la modélisation des surfaces terrestres, la télédétection, l’assimilation de données et l’utilisation de l’apprentissage profond. Je m’intéresse plus particulièrement à l’utilisation de la télédétection pour la météorologie, la modélisation des cycles de l’eau et du carbone continental, l’analyse de l’humidité du sol et de la biomasse végétale, ainsi qu’à la représentation du cycle du carbone dans les modèles climatiques.

My research focuses on land surface modelling, remote sensing, data assimilation, and deep learning applications. In particular, I am interested in using remote sensing for meteorology, modelling continental water and carbon cycles, analysing soil moisture and plant biomass, and representing the carbon cycle in climate models.
