Academic Profile

I completed my undergraduate degree in Geology at Birkbeck, University of London. My final mapping project involved 1.5 months of individual field research in Broken Hill, Australia, studying the high-grade amphibolite facies metamorphic rocks that outcropped in an 8x3km area south of the town.  The mapping area is famous for the iconic ‘Line of Lode’: a hydrothermal deposit, responsible for the largest silver-zinc-lead deposit mine in the world, and had some incredible features, such as a large shear zone running NE-SW, and incredible garnets 10cm in diameter.

While I am interested in high-grade metamorphic rocks, my love is for isotopic and environmental geochemistry, especially climate science and climate mitigation. I am also presently engaged in an IFSTAL course looking at developing effective sustainability practices in the food industry.

Current Research

I am interested in the carbon cycle, and how natural processes, such as the chemical weathering of silicate rocks and phytoplankton productivity, affect the rate of carbon drawdown. My potential project will investigate how these processes can be exploited to capture the excess anthropogenic carbon from the atmosphere, and in particular will consider some of the unknown parameters in the geoengineering method of enhanced chemical weathering.

I am interested in finding out what happens to the CO2 after enhanced weathering; for example, how does the transport process, i.e. within river and groundwater systems, affect the weathered products? Is carbonate precipitated, and if so: how much, where and at what timescales? The end goal is to contribute to the current understanding of the method; in order to ascertain the feasibility of using enhanced silicate weathering on a global scale as one method of achieving the 1.5C target outlined by in the latest IPCC report.
