My research interests revolve around Marine Biogeochemistry and Chemical Oceanography with emphasis on inorganic carbon and nutrient cycling. I am interested in processes controlling the distribution of dissolved inorganic carbon (DIC) and total alkalinity (TA) in the water column and sediments and how these processes may be affected by climate change and ocean acidification. I’m also interested in the formation, recycling and preservation of biogenic minerals (SiO2 and CaCO3) in the ocean and the role of these processes in nutrient availability and CO2 cycling.

As the head of the Analytical Science Team of the Ocean Technology and Engineering Group, I lead a team of scientists developing analytical assays and applying them to autonomous sensors. Our projects span from spectrophotometric assays and electrochemical techniques to molecular assays and biosensor development. Current projects include the development and optimization of analytical assays for the determination of carbonate chemistry parameters (DIC, TA, pH, pCO2), organic and inorganic nutrients (N, P, Si), metals (Fe, Mn) and harmful algal species and their toxins.
