Our research group broadly focuses on the biogeochemical cycling of nutrients and trace metals in the marine environment. We study the sources, sinks and cycling of these important chemical elements, which collectively drive oceanic primary productivity. Under this line of work, we seek to improve the spatial and temporal resolution of chemical measurements in the ocean through the development of novel autonomous microfluidic chemical analyzers. We also study the environmental benefits and impacts of seaweed aquaculture and collaborate with other research groups at MLML to quantify the nutrient removal capacity of various passive nutrient removal technologies.
