Our own world started out as a literal hell — at the onset of the ‘Hadean’ eon the Moon-forming impact melted and vaporized large parts of the adolescent Earth. The resulting ‘magma ocean’ cooled down over a few million years, eventually allowing the water vapor in the atmosphere to rain out and form the earliest oceans not too long after the last giant collision — or so the story goes, according to the combined picture from geochemical, astronomical, and planetary science studies. But does this story hold equally well for other planets, such as Venus, Mars, or even rocky planets in other, extrasolar planetary systems?

Welcome! I am a research fellow in the department of Atmospheric, Oceanic and Planetary Physics at the University of Oxford. I investigate how terrestrial worlds form and evolve 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.
