Professional summary

Research Interests

I work mainly by modelling, with recent or ongoing projects on chemical speciation (metal and proton binding by natural organic matter), acidity and metals in catchments, mercury behaviour and toxicity in soils, soil carbon turnover (using radiocarbon data), the transport and fate of soil dissolved organic matter, metal and proton toxicity in the field (using quantile regression), and coupled plant-soil carbon-nitrogen responses to nitrogen deposition.  I have also led field and laboratory research into the properties of dissolved organic matter in surface waters.

I have practical experience of the analytical chemistry of organic matter, metals, acidity and colloids, and fieldwork on freshwaters and soils.

Before joining CEH I worked on metal-ligand complexation, protein-surfactant interactions, and the non-covalent interactions of carcinogens with cellular proteins and membranes.
