Broadly, my research focuses on biogeochemical processes in the environment. Specifically, I
am interested in understanding processes related to the exchange of carbon dioxide
(CO2) between the atmosphere, surface ocean and its margins, as well as the
environmental consequences resulting from such exchanges. In addition to studying the
upper ocean, my research investigates processes related to the long-term storage of
CO2 and other forms of carbon in the deep ocean and marginal
Biogeochemistry is an interdisciplinary scientific approach to understand the
physical processes occurring in the environment.
I like to conceptualize biogeochemistry as a Venn diagram that includes the four core
disciplines, respresenting the biogeochemical approach. Considering my background and
training as a chemist, chemistry is central to
my biogeochemical approach. Another way I like to think about my approach is
that chemistry is the tool that I use to
understand the physical, biological, geological and chemical processes in the marine
For the most part, my research thus far has focused on biogeochemistry in marginal
Marginal seas are partially enclosed bodies of marine water, oftentimes being
situated adjacent to the open ocean and bound by its margins.
The ocean's marginals can be defined by various features, such as by the continental
shelf, a country's exclusive economic zone or by depth.
For my research, the margins refer to water-column depths of less than 1200 meters
(approximately 0.75 miles), and marginal seas are bound from the ocean by shallower
sills, with few exceptions.
One such exception would be the Caribbean Sea, due to the narrow passageways that
connect its basins to the North Atlantic, which are deeper than 1200 meters yet
shallower than 1820 meters.
Marginal seas that I have studied include the Arctic
Black Sea1,3,4,5, basins of the
Caribbean1, Chesapeake Bay, and the Gulf of
In addition to the marginal seas that I have studied, I have either worked in or
studied other regions of the world ocean, including the Bering Sea,
Drake Passage6, Gulf of Alaska, Ross Sea, and the Southern
