My work at BGI

I am interested in characterizing ecosystem functional properties from space using model-driven approaches. The challenge is that connections between these properties and the radiation remotely sensed are not always direct or strong. To solve this problem, I rely on radiative transfer models coupled with SVAT or ecosystem models to establish formal connections between both. The overarching goal is to develop a new generation of remote sensing algorithms capable of monitoring new dimensions of ecosystems' state and responses.

In the context of the MoReDEHESHyReS, I have developed data assimilation methods to characterize biophysical and functional in ecosystem stations. The combination of hyperspectral data and fluxes provide reliable estimates of these parameters. The combination of models and observations also allowed improving these models. I the new project oBEF-Accross2 I use physical models and machine learning to decipher how functional diversity codifies in remote sensing signals.

I addition, I collaborate with multiple researchers to acquire, interpret, and model spectral information in the context of vegetation studies. I am also vice-leader of the Working Group 1 of the COST Action CA17143 SENSECO, dedicated to the study of spatial scaling.
