Interests: organic geochemistry, biogeochemistry, geomicrobiology, nanogeology, coastal oceanography, contaminant remediation. The overarching goal of much of our research is to understand the processes that lead to the preservation of organic matter in sediments and soils and aquatic systems, as well as the influence of humans on these processes. Of particular interest is the relationship between organic matter, minerals (including mineralogy, surface morphology and chemistry, and the role of nanopores) and microbes. Research currently in progress or planned include 1) lipid biomarker studies of estuarine and coastal systems (Chesapeake Bay and Naples Bay, FL) to reconstruct the history of human-related alteration and eutrophication, 2) examination of the organic geochemistry and mechanism of organic matter preservation in Amazonian black earth soils (terra preta), 3) dissolved organic matter cycling in groundwater (the Floridan karst Aquifer), 4) examination of geomaterials for nanoporosity and organic matter preservation potential, and 5) examinations of organic matter transformation in riverine-ground water systems by abiological processes including mixing, photo-degradation and mineral adsorption (Suwanee River, FL) 6) use of biochar to enhance soil fertility and C sequestration, 7) understanding oil distribution and degradation following coastal spills.
