Champa Wijekoon, Ph. D.
•Improving Canadian crops and investigating the bioactive molecules that may provide significant benefits to our health. I also investigate the applications and roles of genes and microbial endophytes important in selected bioactive molecule synthesis, and on improving Canadian grown crops with desirable traits to use them as functional food.
•Collaborative work studying the role of bioactive molecules of Canadian grown crops in health. This include understanding the molecular basis of the major/specialized/under-utilized crops and improving them in producing specific bioactive molecules
Current research and/or projects
1. Prairie fruits as functional food
2. Assessment of polyphenolic and fatty acid profiles in current Canadian barley grain and malt and investigation of brewers’ spent grain as a source for bioactives in improving human metabolic health.
3. Endophyte microbiome of barley.
4. Creating value from cull cherries.
5. Climate change and vegetable crops.
6. Smart Vertical Farm for Health in Northern Communities.
7. Fungal endophytes for increased production of agricultural crops.
8. Potential of oat-derived compounds in the prevention of the development of hypertension and heart disease in spontaneously hypertensive rats.
Research and/or project statements
Improve Canadian crops that contain bioactive molecules that can bring significant benefits to our health.
To study the applications and roles of genes and enodolytes important in the synthesis of selected bioactive molecules and to improve Canadian agriculture with desirable traits for use as functional foods.
