Postgraduate

I’m supervised by Professor Ros Rickaby and Professor Gideon Henderson, working as part of the NERC GGREW (Greenhouse Gas Removal by Enhanced Weathering) consortium. The wider aim of this broad project is to establish whether mine waste could be treated with microbes or spread over agricultural land to artificially accelerate the natural weathering process. This would draw down atmospheric carbon dioxide and store carbon as bicarbonate ions in the ocean, in order to achieve negative emissions. My DPhil research investigates the response of calcifying marine plankton in the event that this carbon dioxide removal scheme were implemented. This includes investigating the effect of raised alkalinity on coccolithophores and foraminifera through laboratory culturing experiments both in Oxford and Eilat (Israel).

I graduated from the University of Cambridge in 2017 with MSci in Natural Sciences (Earth Sciences) and BA in Geography & Earth Sciences.

I am also keen on science communication and outreach.
