Current/Recent Programs: 

Functional consequences of changes in tree hydraulic architecture during growth, coordination of leaf and stem water transport, leaf hydraulics, functional consequences of stem water storage, carbon partitioning in trees and physiological roles of nonstructural carbohydrates, how water utilization scales with tree size within species and among different species, hydraulic redistribution of soil water by tree roots, characterizing physiological convergence among co-occurring species. The preceding research has been carried out at sites in the Pacific Northwest, Panama, and Brazil.
