The overarching goal of my research is to better understand how molecular interactions control the reactivity and cycling of trace-elements in the terrestrial and marine environments. My work focuses on the mineral-microbe-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 micro-nutrients and the retardation of contaminants in the subsurface, both now and in the past.

Current research areas include determining the reactivity of abiotic and biotic minerals towards trace-metals, including Ni, Cu and Cr, and macro-nutrients, including P and C; investigating biogeochemical controls on freshwater and marine chemistry, including trace-metal concentrations and stable isotope compositions; and applying mineral-water interface research to the understanding and development of novel proxies for palaeo ocean redox and biogeochemical processes.

My group combine novel experimental sorption and stable isotope fractionation studies with synchrotron-based X-ray spectroscopy, quantum mechanical modelling and aqueous geochemical modelling.
