About me

Welcome, and thank you for your interest!

I’m Arnaud Salvador (he/him/his), a junior professor at the Institut de Physique du Globe de Paris (IPGP), Université Paris Cité, in France.

My research focuses on developing and applying planetary interior and atmospheric models to better understand the habitability of rocky planets, from their ancient past to the future insights provided by next-generation observatories.

I’m particularly interested in the evolution of magma oceans, their outgassing, solidification, and cooling in interaction with the atmosphere. This work has important implications for the early formation of water oceans on Earth, Venus, and rocky exoplanets.

I also explore how future direct imaging observatories, such as the Habitable Worlds Observatory, can retrieve atmospheric and surface conditions from distant worlds, helping to refine instrument designs and optimize strategies for identifying Earth analogs beyond our solar system.

Finally, I investigate how volatiles are distributed among planetary reservoirs and how this distribution couples to interior structure over the evolution of rocky planets, informing the interpretation of mass-radius-age measurements from PLATO.
