Main Research Fields

 

 

My main research deals with internal (crustal and core) planetary magnetic fields for Mercury and Moon. 

For Mercury, I use in-situ magnetometer data in order to construct core field maps at constant altitude over the northern hemisphere. I also study the constrains on the early dynamo by studying its crustal magnetic field. 

For the Moon, I study its crustal magnetic field that helps to constrain the early history of the Earth’s satellite. 

At ESA, I have the chance to collaborate with the scientific BepiColombo team.
