>Research Interest

I work in the Ocean Modeling Group at the University of Maine. My research interests broadly cover the interactions of physical, biogeochemical and optical processes in the ocean. Numerical models and all kinds of satellite data combined with in situ measurements are my main resources to study these processes. I am interested in studying the ecosystem responses to physical forcings in differnt spatial and temporal scales, including the climate change effects. We are currently working on the physical and biogeochemical structures of mesoscale eddies and submesoscale processes in different regions of the Pacific Ocean and examining their impacts on the large-scale carbon cycles.
