Areas of Specialization

Research

My primary interests lie in the cycling of biologically important elements, with a particular focus on the marine nitrogen cycle. On-going projects involve: 1) changing nutrient status of the Southern Ocean; 2) biogeochemical cycling within low latitude upwelling systems; 3) Linkages between nutrient status in the polar oceans and low latitude productivity.
