Research

My research is in the area of plant pathology, specifically fungal diseases of fruit trees (apple and cherry primarily).  I have published papers on a variety of diseases: foliar (apple scab, cherry leaf spot), cankers (Leucostoma canker), and root rots (Armillaria root rot).  My current research focuses on fungicide resistance (population genetics, mechanisms, and management).
