My research is fundamentally based on aqueous and isotope geochemistry. I investigate Earth’s global carbon cycle on both modern and geologic timescales.
My academic background is in understanding silicate chemical weathering, a natural process with controls Earth’s atmospheric CO2 levels on long timescales, and ultimately regulates global temperatures. To this end, I conducted studies on chemical weathering around the world. My research has addressed the growing debate on whether chemical weathering of volcanic terranes, such as Iceland, have a disproportionally large impact on Earth’s long-term atmospheric CO2 levels, as well as challenged the long-held assumption that silicate chemical weathering beneath ice sheets is minimal, and investigated the extent to which plant biogeochemical cycling alters the primary signatures of weathering in rivers.
Over the last few years, I have transitioned into studying Enhanced Weathering (EW), a carbon dioxide removal (CDR) strategy that accelerates natural chemical weathering to combat climate change. EW optimizes the controls on chemical weathering such that large quantities of CO2 are sequestered on human, rather than geologic, timescales. As part of the Leverhulme Centre for Climate Change Mitigation (LC3M), I worked to implement the first large-scale field tests of terrestrial EW at agricultural sites in the American Midwest, Malaysia Borneo, and the United Kingdom. Presently, I serve as the Director of Scientific Operations at Project Vesta, where we are conducting fundamental research in coastal EW and launching the world’s first pilot trial of coastal EW in the Caribbean.
