I study mycotoxins in all cereal grains. My research focuses on finding ways to mitigate mycotoxin occurrence. I use latest analytical tools such as mass spectrometry to identify, detect, and quantify them.

Mycotoxins are secondary metabolites produced by fungi infecting crops and contaminating cereal grains. These mycotoxins are harmful to human and animal health. Fungal infection and mycotoxin production reduces yield, quality, and trade-value of cereal grains.

Current research and/or projects

My research supports the cereal and pulse science sector addressing threats to food safety and security because of mycotoxins, investigating effective ways to mitigate current and emerging mycotoxins in cereal grains, improve Canada's position to supply safe food to all Canadians as well as to meet global trade safety standards concerning mycotoxins.

Research and/or project statements

  1. Fusarium Head Blight/Deoxynivalenol mitigation in cereal grains (Wheat, Barley, Oats)
  2. Crop rotation and fungal incidence/mycotoxin occurence
  3. Mycotoxins in canaryseeds
  4. Mycotoxins in oats during storage and post-harvest processing
