Research Interests


Canada is the world’s largest producer of flax, and the majority of that flax is grown in Saskatchewan. The flax breeding program at the Crop Development Centre (CDC) is the largest flax breeding program in North America developing cultivars for western Canadian growers. The main goals of the flax breeding and genetics program are to increase the area of adaptation where flax can be grown successfully and provide better genetics for improved agronomic performance and seed quality for the industrial, human health, and animal nutrition markets. To inform the breeding of flax, my research programs centres around understanding the genetics of traits of economic importance in flax. Specifically, I aim to identify crop characteristics associated with improved agronomic performance and germplasm with novel traits and to explore various breeding methods and genetic tools, such as molecular markers to facilitate the transfer of new traits into new cultivars and breeding lines.
