Broadly, I am interested in interfacing sediment biogeochemistry and ecology with the goal of generating a comprehensive understanding of organic matter cycling in aquatic habitats. How do community structure and species diversity affect carbon pathways and storage within an ecosystem? Alternatively, what are the carbon sources that support organisms and how does organic matter quality affect carbon transfer through the food web? In addition, I am interested in understanding how multiple anthropogenic disturbances interact to affect sediment organic matter composition and biogeochemical processes. To examine these questions, I use a combination of geochemical tracers, including lipid biomarkers and stable isotopes, and observational, experimental, and modeling approaches.
