I started with the Forest Service in 1989 as a plant physiologist for the Riverside Forest Fire Lab, working on interactive air pollution stresses on forest species. Prior to the Forest Service, I had worked on soil warming in permafrost forest ecosystems in Alaska and eucalyptus biomass research in southern California. I have recently moved to the NE to join the Northern Global Change Research Program as the assistant program manager.

In the global change research program, I am developing a carbon budget for the boreal forests of Alaska. I am currently collaborating on nitric acid deposition research which requires physiological and nutrient analysis to measure adaptation of trees to stress. I am especially interested in ecosystem processes and physiological mechanisms in which carbon and nitrogen are obtained and allocated to forest trees under climate change conditions, including elevated levels of ozone, drought, and carbon dioxide.

I would like to add remote sensing and GIS analysis capability to monitor forest health and productivity. I am interested in large scale experiments that can manipulate forest ecosystem processes. I plan on continuing with global change research in the northern latitude forest systems of Alaska and the circumpolar regions.
