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 and blueberry, population and evolutionary biology of fungicide resistance in B. cinerea infecting berry crops 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 using Ascochyta and Alternaria fungi as model systems. Recent projects in the lab also include the molecular, biological and ecological characterization of toxin biosynthetic pathways in Ascochyta spp., the molecular epidemiology and worldwide population structure of eucalypt rust and the systematics and ecology of Morchella spp. (black morels) in the US Pacific Northwest. I collaborate extensively with WSU and USDA researchers as well with numerous other scientists around the globe.
