I am a physical oceanographer in the College of Marine Science at USF. My research interests are how the ocean works and the role of ocean in the Earth system. In particular, I am interested in how the heat, salt, carbon and other biogeochemical tracers are transported in the global ocean. Another of my current research interests is the dynamic processes that can supply energy to ocean mixing, and these processes mainly include internal tides, near-inertial oscillations and mesoscale eddies. My studies are mainly carried out by analyzing in situ measurements and ocean state estimates (ECCO) as well as by running numerical models (MITgcm).
