What do we do?

I have been broadly trained in both marine sediment geochemistry and chemical oceanography, and I am interested in research topics that are related to carbon transport at both the air-sea interface and the sediment-water interface, biogeochemical controls on the fate of sedimentary carbonate, ocean acidification and its effect on calcifying organisms, and applications of stable isotope techniques in oceanographic and geochemical studies. The subjects of my work include seawater, interstatial water (or sediment porewater), marine sediments, marine plants, calcifying organisms (dead or alive). The techinques that I use range from traditional wet chemistry to methods that utilize advanced instrumentations.

Our ongoing research is to study the impact of the Deepwater Horizon Oil Spill that occurred in 2010 on the CO₂ and O₂ dynamics of the northern Gulf of Mexico continental shelf waters, a project currently funded by the Gulf Research Initiative.
