Professional Background:

Director, Skidaway Island Scientific Stable Isotope Laboratory (SISSIL)

Research Interests:

I am a marine and freshwater chemist who uses a variety of tools and techniques to study carbon and nutrient cycling, micro-plastic pollution and their interactions with light (photochemistry), and aquatic life on a wide range of scales. My lab’s main analytical techniques are the measurements of the stable isotopes of carbon, nitrogen, oxygen and hydrogen to determine sources, pathways and rates. In addition my lab uses different spectroscopic techniques such as X-ray and Raman microscopy to explore processes at the smallest scales. I particularly enjoy working out new techniques to allow for different perspectives on environmental problems. Currently I am funded by NSF to study the photochemical conversion of dissolved organic carbon (DOC) to CO2 and other inorganic forms of carbon using isotope dilution liquid chromatography-Isotope Ratio Mass Spectrometry. Recently I have become involved in examining the issue of plastic pollution in Georgia’s waters, especially the issue of microplastic contamination. This work is in collaboration with Dodie Sanders of UGA-MAREX, and involves the active participation of a variety of volunteers in sample collection and processing.
