Agroecology; Diversified Farming Systems; Multi-functional Agriculture; Political Economy of Agricultural Development
My research explores the tradeoffs and synergies between biodiversity and agricultural production. I am interested in multi-disciplinary and applied approaches for studying the influence of biodiversity in and around farming systems on the provisioning of important ecosystem services to and from agriculture, including natural pest regulation, crop pollination, biodiversity conservation, reduced global warming potential, nutrient leaching, productivity, water filtration and soil quality conservation.
My dissertation research examines the effect of planting multiple flowering cover crop species on the regulation of key insect pests in California wine grapes: western grape leafhoppers and vine mealy bug. To understand the most important ecological factors influencing arthropod population dynamics, my research tests multiple theories of conservation biological control. With multiple field and laboratory experiments, the study quantifies population-level impacts on both pests and natural enemies and analyzes the biological mechanisms (e.g. improved longevity, fecundity, and rates of parasitism by beneficial insects) theorized to be enhanced through the addition of floral resources. Through collaboration with UC Berkeley researchers my research quantifies the influence of landscape complexity - the area and composition of non-crop habitats surrounding vineyards - on biological control.
