Research Topic:
Physiological, molecular, and field studies of fungal pathogens of blueberries; research on molds affecting food.

Research Program:
My research focuses on fungi that are pathogens of plants. Research projects in my laboratory examine the genetic diversity, physiology and molecular biology of various fungal pathogens and applied aspects of control of fungi that attack lowbush blueberry. A major focus of my research is mummy berry disease caused by Monilinia vaccinii-corymbosi and a disease identified in Maine for the first time in 2009, Valdensinia leaf spot, caused by Valdensinia heterodoxa. Current research interests include evaluating the genetic diversity of M. vaccinii-corymbosi in lowbush blueberry, determining the genetic relatedness of lowbush blueberry clones that differ in their levels of mummy berry disease severity, examining the mode of infection of M. vaccinii-corymbosi and V. heterodoxa, and determining the major methods of spread of Valdensinia leaf spot. Laboratory personnel are also involved in evaluating lower risk and organic materials and management techniques to control disease and providing information on the use of forecasting methods to improve effectiveness of disease control.
