Lecturer in Biogeochemistry
The overarching goal of my research is to better
understand how molecular interactions control the reactivity and
cycling of constituents in the terrestrial and marine environments.
To this end, 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 biogeochemical cycling of micro-nutrients, the retardation
of contaminants in the subsurface, and the generation of ore-forming
fluids.
Current research areas include probing the chemical reactivity of
the abiotic and biotic mineral-water interface; investigating key
biogeochemical controls on freshwater and marine chemistry; and
applying mineral-water interface research to the understanding and
development of novel palaeoceanographic proxies for ocean anoxia
and long-term climate change.
Work combines synchrotron-based X-ray spectroscopy,
quantum mechanical modelling and aqueous geochemical modelling with
novel laboratory sorption and stable isotope fractionation experiments.
