My research interests focus on both biotic and abiotic regulators of dissolved organic carbon (DOC) cycling across a wide range of tidal and non-tidal wetland types. I have a strong background in enzymology, particularly microbial extracellular hydrolases, wetland soil characterization, spectrophotometric and spectrofluorometric methods, and DOC-mineral sorption. My current research is focused on better understanding organic carbon partitioning between the tidal wetland soil mineral phase, microbial biomass, and the dissolved phase in response to changes in both redox potential and microbial priming by rhizodeposits over time.
