I conduct research on how trees and forests respond to environmental changes and, conversely, how they can be managed to moderate environmental changes. My research draws on physiological and ecosystem ecology to explore how tree and forest-scale water and carbon cycle processes respond to global change factors, including changes in water availability, woody plant encroachment, extreme weather events, and urbanization.
