Research

Current research interests include quantifying plant response to environmental change, modeling plant, regional, and global carbon and water cycles, and incorporating emerging capabilities of plant genomics into studies of plant physiology and ecology. Field experiments are conducted to examine the response of plants to atmospheric CO2 enrichment, drought, and warming, focusing on carbon, water, and energy exchange. Mechanistic understanding gained in these investigations is incorporated into models and used to assess leaf, plant, stand, and ecosystem-scale responses to global climatic change. Studies are being expanded to examine role of plants and microbes in biosequestration, what new approaches can be used to model hierarchical systems in ecology; and how sensors and sensor networks can best be developed and deployed for high-resolution measurements in the ecological sciences.

Description of Research:

  • Physiological response of plants to global environmental change
  • Whole-tree water use and environmental control of canopy transpiration
  • Growth and maintenance respiration of leaves and woody tissues
  • Plant water relations
  • Carbon sequestration in plants and soils of terrestrial ecosystems
  • Individual-based modeling of forest succession
  • Physiological genetics
  • Advanced instrumentation for the ecological sciences
