Summary of Expertise

In my research group we focus on interdisciplinary studies of agro-ecosystems in both coastal California and overseas with a goal of improving the sustainability of current agricultural production systems. To this end our research includes studies of fertility management and nutrient cycling, organic agriculture, ecological approaches to management of pests and diseases, biodiversity and ecosystem services in agricultural landscapes; international agriculture development and resource management primarily in sub-Saharan Africa. In our work we use a combination of on-farm, experimental, landscape and participatory research approaches, with an emphasis on involving farmers in the research process and on extending research findings to a range of audiences.
