Peter Homann received degrees in chemistry from Case Institute of Technology (B.S., 1975), natural sciences from Western Reserve College (B.A., 1975), forest science from Yale School of Forestry and Environmental Studies (M.S., 1977), and forest resources from University of Washington (Ph.D., 1988). Peter was a post-doctoral associate at University of Minnesota and then a research associate and research assistant professor at Oregon State University. He joined the faculty of Western Washington University in 1996.
