We study how humans alter ecosystems, whether these alterations will feed back to further impact global change, and what this means for humans.

We combine quantitative modeling and experimental methods to address these complex questions, with a focus on identifying the mechanisms underlying ecosystem processes.

Human impacts on ecosystems are widespread and diverse, so we work in a variety of environments including grasslands, forests, and agriculture.
