    • She served on the AOAC (US) Stakeholder Panel for Infant Formula and Adult Nutritionals (SPIFAN) as an expert on folate, Vitamin D and Vitamin C analytical methodology.
    • She was a member on the Folate Technical Advisory Group of the Food Standards Australia and New Zealand (FSANZ) 
    • She was the co-cordinator of OCEANFOODS (INFOODS, FAO) until 2016.
    • She is a member of the International Humanitarian Food Science and Technology Network.
    • She is on the Editorial Board of Food Frontier; and an Associate Editor and Review Editor for the journal Frontiers in Nutrition.

My Research Activities

Research Interests:

  • Food composition and development of analytical techniques (biological and chemical) for nutrients in foods
  • Fortification of foods with micronutrients: technologies, bioavailability in humans
  • Development of isotope dilution methods for the analysis of vitamins and other bioactives in foods using LC-MS techniques
  • Bioactive compounds in foods and their activities in vitro and ex vivo
  • Micronutrient bioavailability in humans using stable isotopic studies; ex vivo cell culture techniques
 

Current projects include:

  • Vitamin analysis of foods especially folate, cyanocobalamin and vitamin D (immunoassays, microbiological assays and LC-MS analysis of vitamers using stable isotope dilution assays)
  • Biodiversity of nutrients in plant-based foods (genotypic variations) esp. cereals and legumes
  • Fortification of foods (rice and wheat flour) with micronutrients (folate, iron and beta carotene) using edible coating materials and processing methods
  • Bioactives in fruits (analysis of phenolic compounds using stable isotope dilution methods; GC-MS and LC-MS analysis)
  • Unconventional cereals and their prebiotic potential
  • Improving Vitamin B12 in plant-based foods through fermentation; developing new ingredients of high nutritional value through processing
  • Nutrient recovery from food manufacturing waste streams; agricultural wastes
  • Development of biodegradable nanopolymers as packaging material from agricultural wastes
  • Human intervention trials for bioefficacy of micronutrient fortification of wheat flour in Papua New Guinea
  • Micronutrient bioavailability (folate) from fortified foods and natural sources using stable isotope techniques in humans
  • Bioactive compounds from foods especially lutein and Zeaxanthin, dietary intakes in different age groups, factors influencing intakes (for e.g. age, gender and ethnicity) and prevalence of dry eye disease and macular degeneration of the eye
