Research Interests
  • Biogeography
  • Ecophysiology
  • Ecosystem Ecology
My research is centered on forests and climate change feedbacks and impacts, on linkages between the carbon and water cycles at multiple spatial and temporal scales, and on the global biogeography and biogeochemistry of C4 grasses. My group uses a variety of measurement and modeling approaches for this research, including thermal imaging, deployment of microclimate and physiological sensors, and ecological and physiological process modeling.
