Research Interests:

My areas of research focus on sustainable turfgrass management and plant pathology and nematology of various horticultural crops. One of the chief dilemmas for turfgrass managers is maintaining high quality turf without using excessive amounts of chemicals. I am interested in evaluating different, low maintenance turfgrass species and cultivars and developing integrated pest management systems with the ultimate goal of achieving a high quality end product while combating pests including diseases, insects and weeds. More recently, my research focus has been on the study of root pathogens in turf as well as other crops including strawberries and tomatoes. Ultimately, I am interested in studying plant-soil-pathogen relationships in order to develop sustainable management practices to combat diseases and other pests.

Service Responsibilities:

My primary service commitment is to oversee the turfgrass disease diagnostic clinic housed at the Guelph Turfgrass Institute. The lab diagnoses samples from turfgrass professionals on golf courses, athletic fields and sod farms while recommending practical management schemes specific to each location.

More information about the diagnostic laboratory can be found on the GTI website: http://www.guelphturfgrass.ca/gti-diagnostic-clinic
