I’m interested in the impact of human activities on the composition and function of ecosystems and how changes in these functions affect human well-being, in turn. My dissertation research is primarily on how agricultural intensification in sub-Saharan Africa--mainly through the application of mineral fertilizers--is impacting the diversity and functional capacity of soil organisms and how those changes affect biogeochemical processes that are important for small-scale farmers, such as the formation and decomposition of soil organic matter. I'm keen on understanding this relationship at spatial scales that are relevant to farmers' land use decisions. I am conducting my research through the Millennium Villages Project and am co-advised by Cheryl Palm in the Tropical Agriculture Program at the Earth Institute.

Other work--past and ongoing--has been on the effects of climate and crop diversity on agricultural net revenue and adaptation; the effects of global change factors, such as elevated CO2 and N, on plant communities and ecosystems; the production of CH4 in trees in northeastern forests; and the role of afforestation in urban areas on soil communities and biogeochemical processes.
