Professional biography

I am a Geochemist whose PhD project studies the cause of geochemical variation across the ancient mudstone, sandstone and conglomerate units in Gale crater, Mars. My research involves untangling the environmental and physical effects from that of the sediment source region to understand more about the crust these sediments were eroded from, the processes that have acted on them from erosion, transport and deposition, and what has happened to them post-deposition. This is accomplished through analytical work on NASA Curiosity rover ChemCam (Chemistry and Camera) instrument data as well as thermochemical hydrous alteration models. Since February 2016 I have been a foreign collaborator on the NASA Mars Science Laboratory (MSL) Science Team working with my supervisors Dr Susanne P. Schwenzer and Prof. John C. Bridges (University of Leicester).

My research interests include geochemistry (igneous and aqueous), mineralogy, planetary science and astrobiology. Prior to my PhD I did my undergraduate MSci in Geosciences at Royal Holloway, University of London with an international year at the University of Toronto. My Masters research project studied the geochemical evolution of a Pleistocene volcano near the Reykjanes peninsular in SW Iceland. Studying volcanism in Iceland turned my attention to Martian science as both Iceland and Mars have similar crustal compositions and since then I have been fascinated with Mars exploration and how the discoveries made by previous and current missions have challenged our perception on planetary geology as a whole. Additional to my PhD project, I have also participated in the UK Space Agency Mars Utah Rover Field Investigation (MURFI) which trialled the Exomars Rover PanCam instrument and I also enjoy engaging with the public about Martian science through outreach talks and activities. 

Research interests

Geochemistry, planetary geology, sedimentology, astrobiology, igneous petrology, and astronomy.
