Jeffrey Smith is a PhD candidate in the Biology Department at Stanford University. He works both with the Natural Capital Project and the Stanford Center for Conservation Biology on understanding the impacts of human land use on biodiversity. His empirical work focuses principally on how human land use impacts plant-insect interactions and the subsequent implications on food webs and ecosystem function. He currently studies these questions in the countryside of southern Costa Rica, but has significant field experience on similar topics in the northeastern United States. In addition to his empirical work, Jeffrey employs a variety of spatial modelling techniques to extrapolate local findings to regional and global patterns of diversity. Jeffrey holds a MESc from the Yale School of Forestry and Environmental Studies and a BS from the University of Delaware.
