MISSION STATEMENT

Our lab investigates the microbial and biogeochemical processes that govern how terrestrial ecosystems exchange carbon, nutrients, and reactive trace gases with the atmosphere. We are particularly interested in how soil microorganisms drive nitrogen transformations at the soil-atmosphere interface, from the enzymatic production of nitric oxide and nitrogen dioxide 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 global change 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 atmospheric analytical chemistry.
