Research Interests

My research explores key mechanisms that determine the capacity of terrestrial ecosystems to resist and recover from global change drivers, such as land-use change and intensity, biological invasions, drought, and pollution. Within this framework, I evaluate community- and individual-level responses to different global change drivers using an array of plant physiological, chemical, and anatomical characteristics. My recent research focuses on synthesizing biodiversity-stability relationships in grasslands and the effects of earthworm invasion on biodiversity of multiple trophic levels in North American forests.
