Research Interests:

I try to combine optical measurements with other environmental measurements, so that in situ and remote sensing observations can help describe the constituents and processes in the water or seabed. These measurements include the collection and analysis of hyperspectral ocean color, optical properties, and oceanographic data near and below the water s surface. Example measurements are the reflectance and transmission of light in water, remote sensing of the sea surface, and both airborne and in-water multi-spectral imagery. I ve helped collect optical oceanographic measurements not only from ship and shore based platforms, but also from autonomous underwater and airborne vehicles. My interest lies not only in data and its analysis, but also the preparation and training for successful field operations and the subsequent use of environmental observations.
