Rocky planets larger than Earth are expected to undergo internal geochemical reactions that promote secondary atmospheres rich in water and carbon dioxide. But the highly turbulent fluid flow of internal magma oceans may change this simplified picture. I argue that the magma circulation regime in the interiors of sub-Neptunes may preserve some of the mantle composition inherited from planetary formation, which affects what types of atmospheres we can expect to find with exoplanet surveys.

Welcome! I am a research fellow in the department of Atmospheric, Oceanic and Planetary Physics at the University of Oxford. I investigate the growth and evolution of terrestrial worlds to gain a more comprehensive understanding of how the origins of planets and life are interconnected. Please find an introduction to some of my latest projects below.
