Research Specialty and Interests

My research program is focused on the biology, epidemiology and control of diseases affecting small fruit (berries) in the Pacific Northwest.  Current research efforts in my lab are focused on the biology and epidemiology of Botrytis cinerea infecting raspberry, population and evolutionary biology of fungicide resistance in B. cinerea, and the epidemiology of mummyberry of blueberry caused by Monilinia vaccinii-corymbosi. Other research interests include the role of host specificity in fungal speciation and speciation processes in asexual fungi using Ascochyta and Alternaria fungi as model systems. Other recent projects in the lab include the molecular epidemiology of eucalypt rust in Brazil and worldwide and the systematics and ecology of Morchella spp. (black morels) in the Pacific Northwest. I collaborate extensively with WSU researchers as well with numerous others around the globe.
