Roles and responsibilities

Senior research officer, Natural Products and Analytical Technologies, Aquatic and Crop Resource Development Research Centre

Current research and/or projects

My current research focus is on plant metabolomics, particularly in characterizing secondary metabolites as signaling molecules in plant-microbe interactions. I also work on natural products chemistry projects related to development of natural health products, nutraceutical or functional food ingredients, as well as new extraction and processing technologies for bioactive natural products.  

Research and/or project statements

  • Natural products isolation, characterization and quantitation
  • Plant metabolomics and characterization of secondary metabolites with signaling roles in plant-microbe interactions
  • Natural health products, nutraceuticals, functional food
  • Edible/medicinal plants, dietary herbs, berries
  • New extraction and processing technologies
