My Research

The overarching goal of my research is to better understand how molecular interactions control the reactivity and cycling of bioessential elements in the terrestrial and marine environment. My work focuses on the mineral-water interface and the micro-scale processes that control soil and sediment geochemistry and the composition of natural waters. These processes play key roles in the global biogeochemical cycling of macro- and micro-nutrients and the retardation of contaminants in the subsurface, both now and in the past.

Current research areas include 1) investigating the cycling of micro-nutrient trace metals, including Cu, Ni and Mo, and organic carbon and macro-nutrients, including P, in soils and marine sediments; 2) investigating biogeochemical controls on freshwater and marine chemistry, including elemental concentrations and stable isotope compositions; and 3) applying mineral-water interface research to the understanding of global element cycles and the development of novel proxies for palaeo ocean redox and biogeochemical cycling.

My group combine novel experimental sorption and stable isotope fractionation studies with synchrotron-based spectroscopy and microscopy, quantum mechanical modelling and biogeochemical modelling.
