She has a Ph.D. in Land Resource Science from the University of Guelph, a B.Sc. in Biology from Queen’s University, and a B.Ed. also from Queen’s. Her research program is focused on the development of sustainable cropping systems. It is her goal to inform better nutrient management practices for maintaining and enhancing soil health and fertility, while also reducing nutrient loss and environmental degradation. She studies the effects of fertility regimes, crop rotations, crop residue management, cover crops, and tillage systems on soil biogeochemistry (carbon and nitrogen cycling) and crop nutrition in intensive cropping systems, with particular interest in intensive vegetable production.
