My research activities are focused on the evolution of planetary surfaces, in particular the characterization of their multi-scale structure and composition from remote sensing data (spacecraft, UAV, satellite). They are aimed at understanding how they are actually impacted by space weathering, exogenic or endogenic pollution. The main targets studied at this stage are icy moons of the giant planets, planetary rings or the bare soils on Earth. Radiative and heat transfer models are developed and coupled with DEMs to invert those characteristics from multi-scale and multi-instrumental data.
Among the questions of interest currently studied:
- What is the structure of icy regoliths and what may be the actual sources of their erosion or their pollution at cm to m depths
- Why the thermal inertia of icy regoliths is so low and how it relates to their structure at similar depths
- What is the thickness (and mass) of Saturn’s B ring
- How the multi-scale roughness and porosity of surfaces do impact their directional emissivity ?
