Research Interests
My research interests are in the areas of ocean remote sensing, electromagnetic interactions with the ocean, and small-scale surface hydrodynamics. I have developed methodologies for estimating water depth and water quality using optical sensors, and for measuring ocean waves and observing other surface phenomena using shipboard, airborne and spaceborne radars. As part of this work I developed models for the interaction of electromagnetic radiation with the ocean surface, and investigated the relationship between remotely sensed signals and various
geophysical processes such as oceanic internal waves, winds, fronts, and current boundaries. I have also developed microwave emissivity models for the ocean surface and devised algorithms for estimating surface wind vectors over the ocean using passive microwave radiometric measurements. Most recently I developed methods of estimating ocean wave fields and wave spectra from shipboard radar data.
