My research interests lie in air-sea interactions with a focus on ocean remote sensing of wind waves and the air-sea exchange of momentum, heat, and mass including greenhouse gases. Funded projects often involve the use of microwave remote sensing systems including altimetry, scatterometry, radiometry, and synthetic aperture radar as well as in situ measurement techniques and instrumentation - applied at regional and global scales. Our group is also developing observation platforms and sensors to support improved measurements. Recent research includes participation as a Principal Investigator on several NASA science teams including those for SWOT, Ocean Surface Topography, Ocean Vector Wind, Ocean Sea Surface Salinity, and GLIMR.
