Forest Health Specialist, Forestry and Natural Resources Extension


I am a forest health specialist and forest biologist who studies applied and basic aspects of forest pathology (fungi), forest entomology (insects), and forest parasitic plants (mistletoe), as well as their interactions with tree mortality, forest disturbance, fire, drought and Silviculture.  I am Director of the Swiss Needle Cast Cooperative, an applied research cooperative focused on a needle disease of Douglas-fir.  I am also Co-PI for the Permanent Plot System, a long-term vegetation monitoring program sponsored by the USFS Pacific Northwest Research Station and NSF/LTER at the USFS H.J. Andrews Experimental Forest, cooperating with OSU.
