Research

 

Our research encompasses soil mineralogy and environmental biogeochemistry, focusing on molecular-level interactions at the geosphere/biosphere interface, particularly organo-mineral interactions in soils and sediments.

Projects

  • Carbon sequestration in soils, with an emphasis on the minerals and mechanisms contributing to long-term organic carbon stability in terrestrial environments
  • Interactions of microbial metabolites with soil minerals, including the influence of fulvic acid presence on siderophore-mediated dissolution of goethite and other Fe(III)-oxides
  • Geochemistry of inorganic toxins in soils, sediments and aqueous environments. Adsorption and assimilation of contaminants, principally Pb, Cd and As, by jarosite group minerals in soils and associated sediments contaminated by mine waste [with K Hudson-Edwards, Birkbeck].
  • Co-evolution of plants and soils – a comparative approach. Investigation of the evolution of plants and soils in early terrestrial ecosystems
