My current area of research interest is on the role of the ocean in climate variability from the complementary perspectives of coupled ocean-atmosphere modeling and observations. My emphasis is on the study of the thermohaline circulation, western boundary currents, associated eddies and their impact on the world ocean circulation.

I am the director of the Center for Ocean-Atmospheric Prediction Studies (COAPS) which strives to be a center of excellence which promotes interdisciplinary research in air-sea interaction, the coupled ocean-atmosphere-land-ice earth system, and climate prediction on scales of weeks to decades in order to increase our understanding of the physical, social, and economical consequences of coupled ocean-atmospheric variations.

I am also part of a consortium funded by the National Ocean Partnership Program (NOPP) to validate a HYbrid Coordinate Ocean Model (HYCOM) with data assimilation capabilities. The hybrid coordinate extends the geographic range of applicability of traditional isopycnic coordinate circulation models toward shallow coastal seas and unstratified parts of the world ocean. The vertical coordinate in HYCOM is isopycnal in the open, stratified ocean, but smoothly reverts to a terrain-following coordinate in shallow coastal regions, and to pressure coordinates in the mixed layer and/or unstratified seas. The goal of this consortium is to address the principal objective of the U.S. Global Ocean Data Assimilation Experiment (GODAE), namely the depiction of the three-dimensional ocean state in near-real time.
