The Kao-Kniffin Lab at Cornell University

Research in the Kao-Kniffin Lab focuses on the below ground ecology and management of weedy and invasive plants. Invasive plants and weeds are prevalent in managed and natural landscapes, and have been shown to alter terrestrial ecosystem processes. We are examining the underlying microbial-based mediation of plant traits that impact ecosystem function.
