My research centers on the role that microorganisms play in regulating biogeochemical carbon cycling in aquatic environments. We are interested in addressing key questions regarding microbial controls on the transformation and remineralization rates of organic compounds, including natural organic matter (NOM) as well as anthropogenic contaminants. We use a highly interdisciplinary approach by coupling dual carbon isotope analysis along with experimental microbiology and molecular tools to gain new insights into the microbial interactions and metabolic pathways that underpin carbon cycling in marine environments.
