Personal profile
Research Interests
My research intersects several major disciplines, including microbial ecology, biogeochemistry, and ecosystem ecology. The overall goal of my research is to understand how biotic and abiotic factors regulate element cycling in terrestrial ecosystems, the implications of those processes for ecosystem function, and how ecosystems respond to global environmental change. My current work focuses on understanding carbon and nutrient cycling in terrestrial ecosystems. However, I am also involved in a number of research projects, ranging from understanding the links between biological diversity and ecosystem function, the effects of soil nutrient availability on a range of critical ecosystem processes, and the effects of environmental change on tropical, temperate and high latitude ecosystems.
