Current Research

My research focuses on the ecophysiology of forest ecosystems and strives to increase our understanding of how forests respond to disturbance and the role plants play in regulating hydrologic processes. Current research examines how changes in species composition and forest structure alters stream flow in watersheds following mountain pine beetle attack. Other research aims to: quantify the physiological mechanisms that control forest productivity; understand how resource availability controls forest water use; define the role of physiological constraints on species abundance and distribution; and investigate the effects of climate change on ecosystem water and carbon cycling.
