I’m broadly interested in nutrient cycles in aquatic systems and the role of microbes
in facilitating and modulating the Earth system, in particular its climate. I study
how nutrient cycles have changed over time and space and the biological and chemical
role aquatic systems play in shaping climate and Earth’s elemental cycles. My research
to date has centered on understanding how microbe-scale processes determine broader
biogeochemical cycles. My work highlights the significance of microbe-scale environmental
interactions and their controls on global carbon fluxes and climate. I use targeted
experiments to quantify rates of reactions, enzymatic and metabolic, and characterize
community assemblages to understand their role in facilitation of geologic and environmental
processes.
