Research

The research in my lab focuses on how human activities are impacting terrestrial ecosystems, with an emphasis on soil biota and nutrient cycling processes. We are specifically interested in how anthropogenic stressors (e.g., climate change, nitrogen deposition, agricultural management, invasive species) affect the composition and diversity of soil microbial communities and microbial-mediated carbon and nitrogen cycles. We work at the interface between ecosystem science, microbial ecology and soil science, combining microbiological methods with stable isotope analysis and a variety of soil physical and chemical approaches to examine structure-function linkages.
