Research Interests

My research focuses on the impacts of ocean acidification on marine phytoplankton. During my Ph.D. (at POSTECH in South Korea), a main research topic was to investigate the CO2-induced changes in growth rate of natural phytoplankton assemblages and organic carbon production. As a postdoc in Morel’s group, I am interested in the bioavailability of iron (Fe), an essential cofactor of enzymes utilized in photosynthesis and respiration in phytoplankton, under acidified ocean conditions. The bioavailability of Fe depends on its binding to organic compounds and the rate of dissolution of Fe minerals. My aim is to understand how these processes are affected by acidification and the resulting change in the bioavailability of Fe to phytoplankton.
