My research focus is on the analysis of spacecraft tracking data of various types (radio, altimetry, imagery) in order to learn more about the geophysics of planetary bodies. During my Ph.D. thesis, I used radio tracking of Mars orbiters to measure the density of the upper layers of the Martian atmosphere. Since, I have used the altimetric data from several NASA/GSFC laser altimeters to model gravitational anomalies, construct high-resolution topographic models of the Moon and Mercury, and improve spacecraft trajectory reconstruction to enable the co-registration of the varied data acquired by the Lunar Reconnaissance Orbiter instruments.
I have also studied the illumination conditions in the polar regions of the Moon and Mercury, and how they relate to the volatile distribution.
