The University of Washington College of Forest Resources is a leader in the international study of environmental stresses on tree physiology.   Professor Thomas Hinckley’s research focuses on the water and carbon physiology of trees and woody shrubs. His research and teaching have taken him to Austria, Canada, China, Finland, Germany, Italy, Japan, South Korea, Turkey, and Venezuela. Most recently, Hinckley has worked on the water relations of short rotation, hybrid cottonwood trees, on 65 meter tall, old-growth Douglas fir trees, and on young to very old Pacific Silver fir trees. Hinckley is currently the principal investigator on the College's second Multinational Collaborations on Challenges to the Environment project, sponsored by the National Science Foundation-IGERT.
