Current Research
My current work is focused on developing and applying decision-support systems for environmental analysis and planning. I have led development of the Ecosystem Management Decision Support (EMDS) system since 1995, a general solution framework that has been applied to many domains, a variety of spatial scales, and in various places around the world.

Past Research
Recent major applications of EMDS that I have supported include decision support for (1) watershed analysis (Northwest Forest Plan), (2) forest fuels evaluation and fuel treatment planning (Forest Service, National Park Service, U.S. Fish and Wildlife Service, USDI Bureau of Land Management and Bureau of Indian Affairs), (3) integrated restoration and protection strategy (Forest Service Region 1), (4) maintenance of dispersal habitat for the northern spotted owl (Washington Department of Narural Resources), and (5) soil impacts associated with logging and wildfire (Okanogan-Wenatchee National Forest).

Research Interest
  • Logic modeling
  • Decision analysis
  • Geospatial analysis
  • Decision support
  • Quantitative landscape ecology
Why This Research Is Important
Contemporary natural resource management typically involves implementing concepts and principles of adaptive ecosystem management in the context of large, complex, and abstract problems, and often requires integrated solutions over two or more spatial scales or multiple assessments spread over time. This research has resulted in the deployment of one of only a very few decision-support technologies capable of addressing all these complexities in a relatively comprehensive and pragmatic way.
