MISSION STATEMENT

Our lab investigates the microbial and biogeochemical processes that govern how ecosystems cycle carbon and nutrients. We are particularly interested in how soil microorganisms drive nitrogen transformations at the soil-atmosphere interface, from the enzymatic production of reactive trace gases to the biogeochemical feedbacks that scale these processes to ecosystem and global levels.

​

Our work spans natural and managed landscapes, and is motivated by a fundamental question: how will accelerating anthropogenic influences alter the biogeochemical cycles that underpin ecosystem function and atmospheric chemistry? To answer this, we combine replicated field experiments, controlled laboratory incubations, and microcosm approaches with techniques drawn from molecular microbiology, stable isotope biogeochemistry, and analytical chemistry.
