Areas of Expertise:

  • chemistry, molecular structure and functional properties of starch from various plant sources
  • resistant starch: formation, characterization and functionality
  • alteration made to starch due to physical, chemical or biochemical means
  • potato quality with emphasis on glycermic index, acrylamide, and digestibility in vitro
  • thermal analysis including glass transition and heat capacity of biopolymers.

Current Projects:

  • Understanding starch chemistry, structure/function, interaction, modification, and utilization as well as the role of starch and starch derivatives in the process and quality of food and non-food products
  • Low glycemic index (GI) starch from Canadian grown pulse
  • To develop novel starches from various Canadian grown plant crops (e.g. potatoes, corn and pulses) as a functional food ingredient and for biodegradable materials application to add value to agricultural crops
