Bio: 
David Shaw is a biologist and Forest Health Specialist with Forestry and Natural Resources Extension and Professor in Forest Engineering, Resources and Management as well as an adjunct professor in the FES department. His PhD focused on root disease in manged western hemlock forests of western Washington State. After graduate school, he was employed by University of Washington at two field stations in Forks (1991-1994), and Wind River (1994-2005), Washington. He came to OSU in 2005 where he works on forest entomology, pathology, ecology, and management of planted and natural forests. Dave is no longer accepting graduate students.
