Content / Work

My research focuses on analyzing the 13 years of Cassini/VIMS hyper-spectral observations of Titan in the near-IR to globally map the surface reflectivity. For this, I developed a radiative transfer model to correct for gaseous absorption and aerosol scattering to retrieve the surface albedo. My research covers both observational and theoretical aspects. I have gained experience in reducing and analyzing observational data (Cassini/VIMS, Huygens/DISR, Very Large Telescope, and JWST/NIRSpec and NIRCam), and developing radiative transfer models to interpret these observations.
