Research
I am a chemical oceanographer with an early marine biology background. My research path has been from clams to metal chemistry to ocean optics to satellites; the result of following interesting interdisciplinary problems. Specific interests include:
Aquatic Photochemistry: It significance to redox chemistry and reactive oxygen species, carbon cycles, trace gases, alteration of dissolved organic substances, and relations of these to optics and biological processes
Trace element & trace metal redox chemistry: Processes controlling chemical distributions and biological productivity
Ocean Optics and Remote Sensing: Algorithm development for study of photochemical and photobiological processes over regional and global scales
Analytical method development: Evaluation of photochemical and redox reactions at very low environmental concentrations
