My research focuses on biological processes in Antarctic ecosystems, physiological ecology of phytoplankton, the Antarctic food web, and the HPLC-based determination of photosynthetic pigments. I am also interested in biogeochemical studies, particularly in understanding air-sea CO₂ fluxes and the role of phytoplankton in global carbon cycling.
