I am a physical oceanographer interested in large-scale ocean circulation.  Overall, my research focuses on the ocean’s role in climate variability and climate change.   I am interested in the large-scale meridional overturning circulation of the ocean and how that circulation impacts the transfer of heat, salt and anthropogenic carbon dioxide from one part of the ocean to another. Recent research of mine has also been focused on understanding the physical controls on ocean productivity.  I am interested in how the ocean’s primary productivity will respond to climate change and, as such, am researching how and whether ocean stratification plays a role in those expected changes. I like to think that my research is driven by interesting questions about how the ocean works and conducted with a variety of tools such as data analysis, observational programs, modeling and, as needed, theory.
