Research interests
My research focuses on the internal structure of giant planets. Using gravity data from the Juno mission (since 2016), I try to infer the properties of the interior of Jupiter. This work will help us to better understand the formation of our Solar System. Besides, a better comprehension of Jupiter's interior is key to study and characterize exoplanets.
