Biogeochemistry of freshwater systems

My current research involves the characterisation of dissolved organic matter (DOM) in UK freshwaters in relation to inorganic nutrient export from a wide variety of catchment source areas. I am currently working as a postdoctoral research assistant funded under a NERC Large Grant (the DOMAINE programme). The DOMAINE programme aims to assess the origins and rates of Dissolved Organic Carbon (DOC), Dissolved Organic Nitrogen (DON) and Dissolved Organic Phosphorus (DOP) flux to aquatic ecosystems as they vary over time and space in relation to catchment character, hydrological function and nutrient export. The project will also aim to assess the availability of DON and DOP to riverine phytoplankton and macrophytes and their contribution to N and P uptake by these functional groups.

My work on the programme involves the quantification and characterisation of DOM using a combination of both traditional nutrient analyses combined with novel approaches including excitation emission fluorescence spectroscopy to determine the environmental controls on DOM delivery to riverine ecosystems.
