Research

My research examines the structure and function of river microbial communities. Our work aims to understand how microbial communities are influenced by the landscape, transport and transform carbon, and shift in time, space, and function from headwaters to the ocean. We work in watersheds across North America and in the tropics to identify a common set of watershed "rules of life", and employ a combination of molecular, ecological, and geochemical approaches to answer our research questions.
