Staff Profile
After completing my first degree in geology with planetary science (The University of Manchester) I completed an M.Sc. in Geology (Uppsala University) followed by a PhD on the reactivity of the Martian regolith (Newcastle University). This is my first postdoctoral position. As well as rock-water reactions I have a keen interest in planetary science, using our understanding of geochemical processes on Earth (gained in the laboratory or in the field) to interpret extra-terrestrial environments.
I'm a member of the Earth, Ocean and Planetary Sciences (EOPS) group within the School of Natural and Environmental Sciences. My primary research interests are rock-water reactions in the deep biosphere and their potential relation to other solar system environments. I am also involved with a project investigating the mineral chemistry of plagioclase phenocrysts from the Izu-Bonin rear arc.
Current projects:
CERBERUS - Assessing the role of geological faulting in generating oxidants for microorganisms in the hot biosphere, both today and on early Earth.
(research.ncl.ac.uk/cerberus/)
Izu-Bonin rear arc - Investigate the generation and evolution of magmas and the architecture of the magma plumbing system associated with Unit II in the Izu rear arc at International Ocean Discovery Program (IODP) Site U1437.
