Research

I am interested in the bulk chemical composition of extrasolar planets, and the similarities between Earth and extrasolar super-Earths, as well as the architecture of exo-planetary systems and the formation and evolution of extrasolar planetesimals. My research currently focuses on how polluted white dwarfs can offer a unique insight into the bulk composition, formation location, and geology of extrasolar planetary material. My primary supervisor is Dr Amy Bonsor and my secondary supervisors are Dr Nikku Madhusudhan and Dr Mihkel Kama.
