Current Research
My research focuses on understanding the ecophysiological processes that regulate forest production and how these processes respond to management and climate change. Current studies address productivity/sustainability under intensive silviculture, the relationship between silviculture and carbon sequestration, inter- and intra-specific genetic variation in ecosystem productivity and water use, long-term responses to elevated CO2, and short-rotation biomass for bioenergy. The scale of study ranges from gas exchange and biochemistry of leaves, woody tissues, and fine roots, to biomass production and the partitioning and allocation of carbon within plants, to stand level carbon, water, and nutrient dynamics.

Research Highlights
- I Water Use of Intensively Managed Eucalyptus Plantations Studied (2014)
-
In parts of the southern U.S., short-rotation Eucalyptus plantations have the potential to substantially increase forest productivity for biomass and bioenergy but high productivity of Eucalyptus is associated with high water use. Forest Service scientists compared Eucalyptus productivity and water use to those of traditional pines in the southeastern U.S.
