Introduction
I'm an ocean scientist who generally develops methods to make the most of the imperfect numerical models/theories and the sparse/aliased observations we have of the ocean. Recently, my focus has been on improving existing or exploring alternative observational methods to monitor basic ocean state variables. My research has taken two trajectories: 1) I have studied the interactions between the ocean and other components of the Earth system by developing numerical models and running experiments and 2) I have advanced the reconstruction of the ocean’s historical conditions by understanding the information provided by various observing systems about difficult-to-observe quantities of interest. I currently apply these lines of work to the development of data products, forecasting systems, and enhancement of observing systems.
Research
Computational physical oceanography (using models to identify how to improve ocean state estimates as well as parameterize and understand interactions at oceanic boundaries)
Ocean data science (combining information from theories, numerical/empirical models, and observations to estimate environmental conditions as well as assess and design observing systems)
Rachel Carson insisted that, “No one could write truthfully about the sea and leave out the poetry.” Read my papers and you’ll see that I’ve managed to find a way:
