I am a biogeochemist; through my research, I try to understand how plants and soil respond to environmental change and management practices. I have studied carbon and nutrient cycles in a wide range of ecosystems, including grasslands, cropland, and temperate forests. By using meta-analytic techniques, I synthesize findings in my field of research. I also study the role of soil microbes in carbon and nitrogen cycles, using techniques such as incubation experiments, isotopic tracers and analyses of biomarkers. More recently I have started using these techniques to study rice cropping systems, trying to find ways to optimize yields with minimal environmental impact.
