I joined the University of Portsmouth in 2006 as a Senior Lecturer in Marine Biogeochemistry and was promoted in 2013 to Reader and in 2017 to Professor of Environmental Aquatic Chemistry.  Previous to this I held a number of research posts at the University of Southampton, Woods Hole Oceanographic Institution (USA) and Lancaster University.  I have a background in oceanography (BSc and MSc) and environmental analytical chemistry (PhD). I am a Fellow of the Royal Society of Chemistry, the Editor-in-Chief of the journal ‘Continental Shelf Research’ and a core member of the NERC Peer Review College.

My main research interests are water and sediment quality monitoring using in-situ passive samplers for trace metals, nutrients and polar organic contaminants. Other research interests include trace metal and nutrient sediment water interactions (including sediment resuspension), benthic fluxes, contaminant fluxes and transformations and benthic-pelagic coupling. I have worked on a number of NERC funded projects (Macronutrients and Shelf-Sea Biogeochemistry) and currently work closely with a number of UK water supply companies on integrating passive sampling monitoring into their coastal monitoring and river catchment management strategies.
