My research interests include:
- Biogeochemical cycles, especially carbon and within aquatic systems;
- Applications of stable isotope analyses to biogeochemical cycling;
- Stoichiometry of natural systems;
- Continuous data-logging of water chemistry parameters.
My work is largely interdisciplinary and includes collaboration with scientists in ecology, botany, environmental science and hydrology.
In October 2007 I completed a NERC Advanced Fellowship: “Under what conditions do rivers acts as a net sink or source of atmospheric CO2 ?” (2002-2007). The focus of my Fellowship research wasto consider carbon cycling of major riverine species (gaseous, dissolved inorganic, dissolved organic and particulate organic) in a discharge-related context, using a relatively pristine catchment as a case study. Isotopic characterisation is a key analytical tool for my research.
I have maintained an interest in carbon cycling, firstly through environmental controls on biological production in methane, then as an energy flow in ecological studies, and now in budgetary constraints and process recycling in lotic and lentic systems. Previous research on the influence of peatland gas production on peatland hydrology, on field vegetation respiration studies and on freshwater invertebrate functional plasticity reflects the diversity of my interests in the carbon cycle. Past EU funding addressed the importance of fishery discards in seabird diet.
Current fully funded research includes the following: i) quantifying carbon fluxes from freshwater aquatic systems in the Amazon (as part of the NERC consortium grant, Amazonica). Shortly joining me to work on this project will be Dr. Yoko Ishida; ii) CLAD: Carbon Landascapes and Drainage - this will integrate stakeholders with academics to exchange knowledge on the loss of carbon from terrestrial landscapes to drainage system. Seeking funding for this network arose from my research programme to to consider the impact of the construction of Europe's largest on-shore windfarm, Whitelee, on carbon and nutrient export in the catchment drainage systems. The network facilitator is Dr. Simon Drew. Please contact me if you are interested in finding out more about either of these projects.
