Thomas studies the climates of terrestrial planets with state-of-the-art 3D General Circulation Models (GCM). He earned a PhD in planetary sciences at Sorbonne Université in 2016 on Martian water cloud modeling and data assimilation of the Mars Climate Sounder observations. He then went to UCLA to interpret Akatsuki images of the Venusian atmosphere with model development and data assimilation. He later joined McGill University in 2019 to simulate the climates of tidally locked terrestrial exoplanets. At SSI, Thomas currently continues exploring the Venusian climate with cutting-edge numerical models.
