Areas of Expertise:

  • germplasm development
  • biotechnology
  • wheat
  • pathology
  • marker development
  • doubled haploid production
  • genetics
  • marker application

Current Projects:

  • Develop and deploy high yield CWRS and durum cultivars resistant to the wheat stem sawfly, with appropriate IPM strategies to enhance profitability of wheat production in the drought-prone brown and dark brown soil zones
  • Development of genetic technologies and enhanced cultivars to mitigate weather and disease-induced loss of wheat market value and food quality
  • DNA Markers for Common Bunt Resistance in Wheat
  • Genome mapping for grain quality traits of durum wheat
  • Improve colour, protein quality and milling properties of durum wheat to maintain Canada's 60% share of global durum trade and capture increased share of niche market for very strong gluten 'desert durum' quality, combined with genetically-reduced
  • Marker assisted selection and doubled haploid population development for enhanced pest resistance.
  • Marker development through the production and phenotypic characterization of doubled haploid and other genetic populations for pest resistance.
