Mr Matt Roche
Expertise
I am interested in understanding the effects of planetary collisions on the formation and evolution of atmospheres and oceans on rocky planets, and how such impacts onto the Earth can explain its volatile geochemistry.

Research interests
Whilst my past interests have been broad in scope across the Earth sciences, my current research is largely cross-disciplinary, and links together the fields of geology, geophysics, geochemistry, planetary science, and astrophysics.
I study the formation, structure, and evolution of terrestrial in our own solar system and beyond. In particular, I am interested in the giant impact phase of planetary accretion, which I model using smoothed-particle hydrodynamics (SPH) simulations. I am currently trying to understand the effects of giant impacts on the formation and evolution of planetary atmospheres and oceans, and how giant impacts onto the Earth could explain the Earth's volatile geochemistry. Ultimately, I am interested in processes which build and maintain habitable environments.
Previous work from my MSci has involved lab-based experimental biogeochemistry, trying to understand the viability of iron-based metabolic pathways under conditions expected in the ocean of Saturn's moon, Enceladus.
