Professional Interests: Epidemiology and management of potato diseases, soil microbial communities associated with soil and plant health, utilizing beneficial microorganisms to manage plant diseases

Teaching: PSE 457/557, Plant Pathology/Advanced Plant Pathology

Research: Epidemiology and management of potato diseases.Major diseases to be studied include bacterial ring rot (Clavibactermichiganensesubsp. sepedonicus), common scab (Streptomycesspp.), late blight (Phytophthora infestans), pink rot (Phytophthora erythroseptica), and powdery scab (Spongosporasubterraneaf. sp.subterranea). I am interested in studying soil microbial communities that are associated with soil health and plant health, utilizing beneficial microorganisms (or biological control agents) to manage plant diseases. Other approaches include chemical control and fungicide resistance, molecular tools to detect and quantify plant pathogens, varietal resistance, environmental factors that impact disease cycle and its management.
