Fascinated by Astronomy, I am at present in doctorate in LISA (Paris) where I work on the capacity of the ChemCam instrument aboard the Curiosity rover to detect the organic matter in mineral samples (phyllosilicates) and on the photostability of the organic matter contained in mineral matrix, in irradiation, temperature (55°C) and pressure (6mbar) conditions of the Martian surface with the MOMIE experiment (Martian Organic Molecules Irradiation and Evolution).
