My interests are the exploration of Solar System objects and the understanding of their evolution. I am focusing on remote sensing of the solid surfaces of planets and their record of past environments. This research is enabled by space missions throughout the Solar System. Here below more details on my research methods.
Near-Infrared mapping spectroscopy of planetary surfaces
This method enables us to characterize the mineralogy of planetary surfaces by analysing reflected light. Absorption bands of rock-forming minerals, like pyroxene, olivine, phyllosilicates and carbonates can be detected, quantified and mapped across a planetary object. This tell us about how rocks formed, for example by magmatic processes, volcanism or aqueous alteration. I have applied this method on Mars, the asteroid Vesta and dwarf planet Ceres.
Near-Infrared spectroscopy of analogues material
Near-Infrared measurements of analogue materials, such as meteorites, are performed in the laboratory under controlled conditions to provide a ground truth for measurements in space. A variety of aspects affecting the near-infrared properties of a material can be investigated. I have been studying the effects of observation geometry, grain size and mineralogy. I have collaborated in the analysis of samples under low temperature and vacuum conditions using goniometers and low-temperature reaction chambers coupled to spectrometers.
This field exploits optical imagery and 3-D topographic model. Geomorphology, morphometry and stratigraphic relationship give information on the type and time of processes that affected the surface, like impact cratering, tectonic, or fluvial. Time information can be gained with the so-called crater counting technique, or crater size-frequency distribution measurements, coupled with model and chronologies of impact history.
