Biography

My initial background is in electrical engineering and applied physics but curiosity and chance drove me to the field of satellite geodesy, which I have been exploring for almost 10 years now. In the last 5 years, I have focused more specifically on leveraging space geodetic observations for water resources monitoring and modelling. This academic journey drove me from France to Germany and now to Italy.

Research

I currently work on the derivation of parsimonious and physics-informed rainfall-runoff models at the basin scale. These models are purely driven by Earth observations and particularly satellite gravimetric observations from GRACE(-FO) missions, which give a unique insight on the variations of water storage at a regional scale. These inferred models allow the estimation of the total drainable water storage in a basin, a quantity that is almost impossible to measure directly, and the characterization of baseflow dynamics, which is critical for evaluating the availability of water in time of drought. Another objective is to leverage these models to reconstruct long and consistent time series of the main hydrological variables and to analyse their trend evolution. This will eventually help better determine how much and how the water cycle is intensifying as a result of global warming.
