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, pollution and their interactions with aquatic life on a wide range of scales. My main analytical techniques use measurements of the stable isotopes of carbon, nitrogen, oxygen and hydrogen to determine sources, pathways and rates.  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. In addition I have used cutting edge techniques such as X-ray fluorescence spectro-microscopy to look at nutrient and carbon compositions on sub-micron scales.
