Microbial-Climate Change Feedbacks in ​
​Coupled Human and Natural Systems

Microbial Responses to Environmental Gradients

We study the response of microbial community structure and function across long-term nutrient gradients in terrestrial and aquatic systems. At coastal field sites, we also examine interaction of nutrient, carbon, and salinity gradients on microbial community structure and function. We use a combination of field observations, field and lab experiments, and modeling approaches to examine how microbial communities shift in composition and function (e.g., greenhouse gas production, nitrate removal, decomposition) under current and projected environmental stressors (e.g., drought, flooding, salinity).

'Micro'managing Ecosystem Benefits in Human-Dominated Landscapes

We investigate how land use management influences microbial community structure and ecosystem functions. We use a combination of field, lab, and modeling approaches to examine how human and climate-induced environmental changes influence microbially controlled ecosystem services (e.g., water quality enhancement, carbon storage) and dis-services (e.g., water quality impairment, greenhouse gas production).
