As Orchard Specialist in western Oregon, the primary objective of my position is to support commercial tree fruit and nut industries through applied research and Extension. My position is intended to address all aspects of orchard production including site selection, orchard design and establishment, pest management, and marketing, but my specialization is entomology and integrated pest management. My primary responsibilities are to the hazelnut industry, the dominant orchard crop in the Willamette Valley and soon to be one of Oregon's top agricultural commodities.

I am on the graduate faculty for Horticulture and Entomology and can accept students for both diciplines and serve on committees.
