About Me
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).

Good reading...
Experiences
  • Topic : Exploration of Mars by the Curiosity rover. Data processing and interpretation in term of content in organic matter.
  • SAM (Sample Analysis at Mars) and ChemCam (Chemistry and Camera) team collaborator
  • Use of the MOMIE (Martian Organic Molecules Irradiation & Evolution) experiment to work about the photostability of organic molecules and/or clay minerals in martian environment.
  • Use of ChemCam testbed (IRAP - Toulouse) to see if the ChemCam intrument aboard Curiosity is able to detect organic molecules.
  • Synthesis of samples of astrobiological interest (organic and mineral interaction)
  • Topic : Simulation of Gaia type spectra from spectra obtained by in situ telescopes
  • Gaiatisation of the spectral library (visible) of asteroids
  • Writing of a technical report (Gaia DPAC) : Test of the unsupervised classification algorithm
  • Topic : Remote sensing on Mars : Compared Analysis of orbital and in situ spectro-imaging data acquired on the Curiosity rover route
  • Compare the various data of the instruments of Curiosity by the study of the diffetent types of spectra
  • Attempt to connect the in situ measures with those orbital (CRISM hyperspectral imager)
  • Topic : Hyperspectral mapping of the Curiosity landing site
