Research Summary
My research focuses on examining the interplay between terrestrial weathering processes and (i) ocean oxygenation and redox chemistry (ii) atmospheric CO2, and ultimately (iii) the Earth's climate system over modern and geological timescales. In particular, I am interested in silicate, carbonate and sulfide mineral weathering at high-latitude glaciated and permafrost-dominated Arctic regions.

To do this, I apply non-traditional isotopic, elemental and mineralogical tools to better understand geochemical cycling in riverine/estuarine and marine environments
