Planetary Science Archive Lead Scientist / BepiColombo Operation Scientist

 

Main Research Fields

Planetary scientist at the European Space Agency at ESAC, I am coordinating the Planetary Science Archive (PSA) scientific development, and I support the scientific operations of the BepiColombo mission. I am doing active research on the Moon's and Mercury's surfaces, as well as cometary surfaces. As a geologist/spectroscopist, I am interested in surfaces of planets

  • what are their current characteristics: What is the mineralogical composition, what are the grains/rocks arrangement ?
  • how do they evolve: How has the surface that we see today changed, how to account for that in the observations we have ?
  • how do they form: How do we merge the characteristics we see today with our best guess for the surface evolution to understand the initial formation conditions ?

One of the focal point of all those questions is Volcanism. I study visible to near infrared volcanism to decipher its composition, properties, characteristics, to eventually understand how we get to the point we see today.
​​​​​​​Another aspect that help you to understand how we get to the point we see today is Morphology. And If you look at morphology of comets, you can, maybe, see morphologies that are characteristics of the formation of the Solar System.
