I approach research, teaching, and graduate student advising with a “chemical perspective” of oceanography in which the distributions of chemical concentrations and isotope ratios are used to understand biogeochemical processes and the role of the ocean in the global fluxes of oxygen, carbon and nitrogen. As the science of oceanography becomes more interdisciplinary, we seek to understand how chemical tracers can be used to determine rates of physical and biological oceanographic processes that are not possible to constrain otherwise. My main research interests over the past decade have been using gases and their isotopes to constrain net biological fluxes of metabolites in the euphotic zone of the ocean and mixing processes deeper in the thermocline. Our studies of ocean chemistry are slowly transitioning from shipboard sampling to using a variety of in situ sensors on moorings, profiling floats, and gliders.
