Research Interests

My research, teaching and outreach interests broadly involve scaling questions and geospatial applications in forests and ecosystems.  My research activities range from historical remote sensing analysis of tropical deforestation to biogeochemical modeling of ecosystem-climate feedbacks in the Arctic; from airborne measurement of forest structure to national- and global- scale greenhouse gas inventories. I study the drivers of forest disturbance, management and land use change and the associated consequences for ecosystem structure and function. This work involves various tools including field studies, ecosystem observations and experiments, remote sensing, biomass and carbon inventory, and ecological process models.

Prior to my appointment at the University of Maine, I was a post-doctoral fellow in the Institute of Arctic Biology at the University of Alaska Fairbanks and a research scientist in the Climate Change Science Institute at the Oak Ridge National Laboratory. I am currently involved in various collaborative efforts including the interagency North American Carbon Program (NACP), NASA’s Arctic-Boreal Vulnerability Experiment (ABoVE), DOE’s Next Generation Ecosystem Experiment (NGEE-Arctic) and the NSF Permafrost Carbon Network. I am an active member of the American Geophysical Union and the Ecological Society of America, have served the ORNL and LP DAAC User Working Groups, and act as associate editor for Frontiers in Ecology and the EnvironmentRemote Sensing, and the Journal of Forestry.
