Work Summary
We aim to constrain the microbial drivers of soil-atmosphere trace gas fluxes across a range of scales. We constrain the genetic traits for trace gas metabolism and develop new tools for measuring genes and gases in heterogenous soil systems. New understanding is evaluated across a range of model to natural ecosystems where microbial trace gas cycling occurs in the context of environmental forcings and interactions.
Research Interest
Our research is focused on microbe-mediated trace gas fluxes between the soil and atmosphere, their genomic basis, and methods to link gene to ecosystem function in the face of soil complexity and wide-ranging scales. Keywords: Soil Microbial Function
