Research summary

The research topics of Lei Chou are strongly related to global change and environmental issues. She has developed an expertise in the biogeochemitry of carbon and associated elements in the natural environments. Her research activities over the past 15 years have been focused on 1) marine calcification as well as biological nitrogen fixation in relation to ocean acidification and warming, 2) coastal benthic hypoxia, 3) (bio)geochemistry of the phosphorus in relation to eutrophication in the Scheldt Estuary and Belgian coastal zone, 4) the dynamics of silica in the continuum of Scheldt River-Estuary-North Sea, 5) geochemistry of trace metals in the Scheldt Estuary and 6) biogeochemistry of iron and nutrients in the sea-ice. She has also been working on the assessment of dissolution kinetics and solubility of marine biogenic carbonates in relation to ocean acidification.
