Research

I am presently developing an applied research program in the area of tree fruit physiology, with priority given to sweet cherry and pear horticulture, and minor emphases placed on postharvest relations.  Major thematic areas are:  1) Increased production efficiency, 2) Yield security, and 3) Improvement of fruit quality.  These themes are closely linked to the environmental and economic sustainability of the tree fruit industry.
