Thomas explores the atmospheres of terrestrial planets with numerical climate models. He finished a PhD at Sorbonne University (Paris) on the Martian water cycle and data assimilation of the Mars Reconnaissance Orbiter with a Martian atmospheric model. He then joined UCLA to interpret Akatsuki’s observations of the Venusian atmosphere. Since then, he has been selected as a NASA Participating Scientist of the Akatsuki mission. As a postdoctoral researcher at the McGill Space Institute since 2019, he collaborates with Nick Cowan to study the climates of exoplanets in synchronous rotation around their star.
