Our research focuses on the marine nitrogen (N) cycle and its connection to other essential bio-elements such as C, P etc., particularly microbe-phytoplankton interactions and nitrous oxide (N2O) cycling in various marine systems extending from the eutrophic coastal zone to the oligotrophic subtropical gyres. To disentangle the complex N dynamics, we take advantage of multiple C, N, and O stable isotope tracing approaches to examine C and N transformation rates in natural ecosystems and lab culture. The overarching goals of our research are to better understand the ability of the ocean to regulate atmospheric CO2 and N2O during the intimate coupling of the C & N cycle; and how the marine C & N cycle responds to anthropogenic forcing and natural variabilities.
