I am a principal biogeochemist and water quality scientist at the Centre for Environment, Fisheries and Aquaculture Science www.cefas.co.uk. I am an Honorary Lecturer in the School of Environmental Sciences at UEA, where I lead the Ecosystem and Coastal Processes science theme at the Cefas-UEA Collaborative Centre for Sustainable Use of the Seas and I am a PhD and MSc supervisor.

I carried out my PhD in ENV after completing an undergraduate degree in Chemistry at the University of Bath. I joined Cefas in 2001 and have worked on a variety of projects looking at nutrient cycling in UK shelf seas. I am part of the Marine Observations Systems team at Cefas, deploying instrumentation for making in situ observations of the pelagic ecosystem. 

My research interests focuses on investigating nutrient, carbon and oxygen cycling and transport from freshwater systems into the coastal and marine environment. I use high frequency data from in situ observing systems (SmartBuoy, Ferrybox, remote sensing) and ship-based experiments to investigate biogeochemical cycling with the coastal and marine environment. I have also led operational research programmes to investigate the spatial and temporal variability and controls on the marine carbonate system in UK shelf seas. I am interested in understanding and quantifying the controls of oxygen in shelf seas and the potential impacts of climate change on these processes. I have been an investigator on several NERC projects, including UK Ocean Acidification Research Programme, Shelf Sea Biogeochemistry and AlterEco.
