Joana S. OliveiraPostdoctoral Research Fellow
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.
