Global change impacts on C storage and N cycling

A major focus of my research is to understand not only how the relationship between plant and microbial communities vary among ecosystems, but also to understand how these relationships are altered by global change. Specifically, my research has focused on how increased elevated atmospheric O3 and CO2 affect plant-microbe interactions. The significance of global change for biogeochemical cycling is well recognized at broad scales, but the microbial mechanisms that regulate ecosystem responses to global change are not well understood.

Alternative Biomass Cropping Systems & Microbial Processes

A critical gap in making progress toward ecologically beneficial farming practices is an explicit understanding of how soils store carbon (C) and nitrogen (N) over the long term. Farmers are facing new challenges that require management practices for improving soil quality, increasing both belowground (live roots) and aboveground (live cover) biomass, increasing soil organic matter, and reducing greenhouse gas emissions. To identify optimal man¬agement strategies, an understanding of microbial processes that regulate C and N cycling is essential.
