I am a plant pathologist/epidemiologist who specializes in sustainable disease management. My previous and current research focuses on plant disease diagnosis & epidemiology, pathogen characterization/biology/population genetics, disease forecasting, & and modeling, biocontrol of plant disease, integrated pest management (IPM), chemical disease control, host resistance, exploitation of cultural methods (e.g., fertilization) and host physiology to suppress disease development. I have experience with several host pathosystems, but my research has focused mainly on potato diseases, i.e., late blight (Phytophthora infestans), early blight (Alternaria spp), stem canker & black scurf (Rhizoctonia solani), potato early dying (Verticillium dahlia), black dot (Colletotrichum cocoodes).
