Research topics

My main field of research is the microwave remote sensing of land surface parameters (soil, vegetation and snow). The environments studied are very diverse, ranging from semi-arid environments to boreal forest areas and snow-covered regions. I also work on the extraction of physical parameters and the characterization of these environments.
