Current Research

My research focuses on the impacts of environmental stresses such as drought and high temperatures on woody plants. I am also studying complexes of functional traits that may be predictive of how plant species will perform under different climate regimes.

Research Interests

  • Plant physiological ecology
  • Plant hydraulic architecture and maintenance of water transport from roots to leaves
  • Stable isotopes in plants as indicators of integrated physiological responses to the environment

Past Research

I have conducted field research in a broad range of woody plant ecosystems including old-growth coniferous forests, temperate deciduous forests, tropical forests, tropical savannas, deserts, and the tropical alpine zone. Much of the forest work was conducted from large construction cranes that allowed access to the upper forest canopy to make measurements that were previously impractical. I have also conducted research on the phsiological impacts of forest pathogens such as Swiss needlecast and dwarf mistletoe.

Why This Research is Important

Realistic predictions of how individual species, forests, and other vegetation types will respond to changing environmental and management regimes require detailed knowledge of key plant functional traits that govern growth and water requirements and resistance to environmental stress.
