  • Summary Statement of Research Interests

    My research background is as a biological oceanographer and microbial ecologist, primarily interested in microbial activity measurements related to the nitrogen cycle, and how microbes and biogeochemical cycles interact. Involving undergraduates in research is my current major focus, and students have worked on projects such as: mapping of water pollution sources and comparison to socioeconomic data; nitrogen fixation associated with degradation of invasive Sargassum; nitrogen cycling activity and players in aquaponics food systems; and native shoreline community restorations ability to prevent shoreline erosion (associated with the Living Shorelines project run by Orange County Coastkeeper).
