Specialisms

Soil mineralogy, metal cycling, organo-mineral interactions, pedology, soil chemistry

Summary

I am a soil mineralogist and environmental geochemist, focusing on molecular-level interactions at the geosphere/biosphere interface, particularly organo-mineral interactions in soils and sediments. These interactions are fundamental to many soil processes, including the cycling and bioavailability of metals, as well as the long-term stability of soil organic matter, with considerable relevance to carbon cycling. I have a particular interest in siderophores, low molecular weight organic compounds produced by plants and micro-organisms in response to iron stress. These molecules serve mainly to acquire iron for use in metabolic processes, but they are also important in the cycling of other, potentially toxic metals.
