Research Scientist

Research oriented program focused on studying problematic weed science issues which impact Canadian farmers with an emphasis within Saskatchewan and the Canadian Prairies. My program evaluates weed ecology and integrated weed management strategies to provide control of troublesome species and reduce the risk associated with herbicide resistance and environmental stressors.
