Research Interests

  • Development of structure in forest canopies
  • Crown development in individual trees
  • Forests of the Sierra Nevada
  • Long-term changes on forest ecosystems
  • Conifer distribution and autecology
  • World's largest and tallest trees

I am very excited about the new Institute for Redwood Ecology and the Redwood Climate Change Initiative sponsored by the Save-the-Redwoods League. My work with professor Sillett began in the mid-1990s, when we realized we had a common interest in how structural complexity develops in old trees and forests. Since then, we have expanded our research to include many other collaborators and have made great strides in the understanding of above-ground, whole-tree growth and physiology. Our new research thrust will seek to understand both California redwood species over their entire geographic distribution in the face of rapidly changing environmental conditions.
