Weed science, weed ecology, cropping systems

Research Interests:

My research goal is to facilitate the integration of ecological principles into crop production systems. My major area of research has been to design and implement integrated weed management systems for field and horticultural crops grown in Ontario. Selected areas of study have included weed and crop modelling, weed biology and ecology, economics of weed management and managing weeds with herbicides.
