I study physics (such as light and sound propagation and hydrodynamics) for its own sake as well as to understand how it affects biological organisms and sediments. I have been instrumental in the development of new techniques to obtain information on particles in the ocean (bulk size distribution and composition) as well as the development of novel methods and products from satellite ocean color.

A principal thrust of my current research is the use of measured optical properties (absorption, scattering and attenuation) to obtain the bulk properties of the matter in the ocean (e.g. particulate size distribution, composition). Theoretical studies (Mie and T-matrix methods) are used to investigate dependencies that are tested with data obtained in the field. to increase the information we can obtain in-situ on particles and their properties, I am currently getting into Ocean Acoustics.

A second major area of research is the inversion of passive remote sensing. Currently inversions are provided without error estimates. I am working on a method to provide the uncertainties of inverted products.
