I have spent a number of years working on the marine carbon pump, working with the National Oceanography Centre, Southampton, and British Antarctic Survey, Cambridge. Here I focussed on the role of biology in transporting carbon out of the atmosphere and locking it away in the deep ocean. In particular I am interested in the role of krill in driving carbon to the deep ocean in the Southern Ocean.
I am currently working as a biogeochemist for the UK Centre for Ecology and Hydrology, involved in the BIOPOLE project looking at nutrient biogeochemistry in the polar regions.
