Research Focus

I work on diverse fruit crops including tree fruits, winegrapes, and novel crops such as pawpaws and antique apple varieties. Some of my projects have continued for more than a decade, investigating long-term impacts and aspects of perennial crop systems. Current research areas include biological control of soilborne diseases of apples, nutrient dynamics in orchards under various soil management systems, cultural practices to improve winegrape quality, tree root demography, and evaluation of traditional American and European apple varieties for cider fermentation.
