Background Information

I have degrees in Biology from Juniata College (B.S.; 1978) and the College of William and Mary (M.A.; 1982) and a degree in Environmental Sciences from the University of Virginia (Ph.D.; 1990). Between 1991 and 1995, I worked as a Research Associate and Research Assistant Professor in the Department of Forest Sciences at Oregon State University. I have been a faculty member in the Department of Environmental Sciences at Western Washington University since 1995. My research focuses on the regional-scale study of land-use effects on the structure and function of forest ecosystems. My work is heavily dependent on the use of simulation models, GIS and satellite remote sensing. Past projects have evaluated the consequences of forest change for vertebrate diversity and the regional carbon budget. Although most of my work takes place in the Pacific Northwest, I have also been involved in comparative studies of land-use effects on forest structure in other parts of the world. My most recent projects deal with land-use effects on aquatic systems and an evaluation of possible causes for recent declines of Mountain Goat populations in the Cascade Mountain Range of Washington.
