Research Interests

My primary areas of specialization are aquatic biogeochemistry and microbial ecology. My overall scientific interest as a biogeochemical oceanographer is to better understand how carbon and nitrogen cycling in marine systems impacts estimates of global carbon flux. My interests lie not only in assessing sources, sinks, and transformations of carbon and nitrogen in time and space but also in assessing those factors that regulate microbial carbon and nitrogen remineralization and assimilation processes. I am especially interested in evaluating and quantifying processes that impact marine dissolved organic carbon (DOC), one of the largest exchangeable reservoirs of organic carbon at the earth’s surface. My research combines laboratory and field studies to trace carbon and nitrogen flow through coastal and oceanic systems by coupling nutrient concentration measurements together with measurements of stable isotope and natural radiocarbon abundances.

Research that I have currently underway involves the following: evaluating the impact of varying light intensities on phytoplankton DOC/DON release and microbial uptake in coastal and oceanic systems; evaluating the impact of submarine groundwater discharge on the export and/or in situ remineralization of buried carbon in nearshore sediments; evaluating the impact of dissolved organic matter utilization by harmful algal bloom (HAB) species on HAB growth and toxin production; evaluating sediment carbon and nitrogen concentrations and isotopic signatures to reconstruct historical trends of water column quality and productivity; and evaluating the impact of photooxidation on DOC cycling in the Southern Ocean. Past research has involved: tracing in situ hydrocarbon degradation by indigenous nearshore bacterial populations; and evaluating the cumulative impact of cometabolism and photooxidation on hydrocarbon degradation by indigenous nearshore bacterial populations.

In addition to my ocean science research, I have also been involved in education research. Since 1997, through funding from the NSF, I have been working on the development, implementation, and assessment of a postsecondary Ocean Science Concept-driven Interactive (OSCI) teaching model. The OSCI teaching model has been designed for a typical postsecondary 16-week semester class period and setting (i.e. small classroom of 20-40 students or large lecture hall of 100-150 students). This model blends both traditional lecture-based and concept-driven/interactive methodologies through the integration of mini-lectures, readings, writing, and focused group discussions. The ultimate goal of this work is to make this teaching ‘tool’ available to all interested instructors at post-secondary institutions to aid with a transition from a traditional approach for teaching the ocean sciences to one that is more concept-driven, collaborative and interactive.
