    Research Interests

    Mesoscale oceanic eddies; large-scale, low-frequency variability of ocean circulation; coupled ocean-atmosphere variability; satellite microwave radar remote sensing; development of techniques for improving and quantifying signal-to-noise ratio in oceanographic measurements.

    Current Research

    Investigation of large-scale geophysical wave dynamics, air-sea interaction, wind-forced ocean circulation and mesoscale variability from satellite radar scatterometer measurements of wind stress, altimeter measurements of sea surface height and passive microwave radiometer measurements of sea surface temperature.
