Current Scientific Activity
My research activities are centered on the remote sensing of natural surfaces in the domain from 0.4 μm (visible) and 14 μm (thermal infrared). It covers the understanding of radiometric signals (propagation of electromagnetic radiation in a complex environment), the development of mathematical tools to analyze the data (radiative transfer models, spectral analysis, model inversion), and the organization of laboratory or field experiments to validate these models. There are now many applications in geosciences, environmental physics and exobiology. It is essentially a multidisciplinary field of research with many ramifications. After studying the vegetation for 20 years, I am now focused on the study of bare soils (terrestrial and planetary surfaces).
