Our lab studies the benefits (AKA ecosystem services) humans derive from the environment. Through studies of plants, soils, and their interactions, we work to identify and test ways to manage human-stewarded ecosystems like agricultural fields to optimize services such as crop production and limit disservices such as water and air pollution.

Dr. Finney’s lab studies the benefits humans derive from the environment. Our work uses plant community ecology, soil ecology, and biogeochemistry to identify and test ecologically-based approaches to managing agricultural fields, urban green spaces and other human-stewarded ecosystems. It is well-known in ecology, for example, that as biodiversity increases, so do important ecosystem functions such as primary production. Current research in the lab is investigating ways to increase crop diversity in agriculture and, in turn, the ecosystem functions that support food production and reduce environmental pollution from agriculture.
