Research Interests

The overarching goal of my research program is to optimize weed management in agricultural systems. To achieve this, our research aims both to improve our understanding of the basic biological and ecological principles that govern weed population dynamics and to develop highly efficacious weed control technologies. To accomplish this, we conduct both basic and applied research in the following areas:

  • Evaluation of new and existing herbicides in field crops
  • Integrated weed management
  • Biological and ecological constraints on weed population and community dynamics
  • Plant interactions (competition and cooperation) and their role in weed population dynamics
  • Predation of weed seeds in the agroecosystem

Areas of specialization

  • Weed Biology
  • Weed Ecology
  • Weed Management


  • Ph.D. (Weed Science), University of Manitoba
  • M.Sc. (Weed Science), University of Saskatchewan
  • B.Sc. (Agronomy), University of Saskatchewan
