I am focusing my research activities on characterizing planetary surfaces or rings by infrared or visible remote sensing to determine their multi-scale structure or composition. Radiative and heat transfer models are developed and coupled with DEMs to analysis multi-scale and multi-instrumental data. Among questions of interest are: - The structure of icy regoliths exposed to space weathering at cm to m depths - The low thermal inertia of rocky and icy regoliths and how it relates to their structure - The thickness (and mass) of Saturn’s B ring - Multiscale properties of Saturn’s rings, of terrestrial terrains
