My main research topics are planetary science (the study of Solar System bodies' from core to crust) and relativistic astrometry (an accurate mapping of positions and distance of stars in our galaxy). My main expertise is the modeling and analysis of measurements produced by a variety of techniques (including radioscience, altimetry, imagery and astrometry) and their use to recover the interior structure and surface properties of planetary bodies.
In particular, I have worked extensively in the analysis of the MESSENGER, GRAIL, and LRO datasets, to better understand the history and processes operating at Mercury and the Moon, and to prepare for their future human (NASA Artemis) and robotic exploration. Other research topics include the relativistic modeling of light propagation, with particular attention to deep space navigation, tests of General Relativity and high precision global astrometry (ESA Gaia mission).
I maintain active collaborations with research groups in multiple countries where I have worked and lived (Italy, France, Switzerland, USA), and I enjoy developing my research and fostering scientific exchanges in a rich multi-national and cultural environment.
