My broad research interests include: maternal and child health, micronutrients, and global health. I am specifically interested in hemoglobin, iron and zinc biomarkers, the effect of inflammation on nutrition biomarkers, and genetic hemoglobinopathies and blood disorders (e.g., sickle cell, thalassemia).

 I have worked as a Clinical Dietitian at the BC Children’s Hospital, as a Dietitian Manager for Pregnancy Outreach Programs in BC, and as a Regional Nutritionist for the Canada Prenatal Nutrition Programs in Inuvik, Northwest Territories. I have also worked internationally as a Nutritionist for the UN World Food Programme (Rwanda, Malawi, Ethiopia, Italy HQ) and UNICEF (New York HQ, Timor-Leste) in humanitarian aid, operations research, and nutrition programming.

  • A 2×2 factorial RCT to determine the effect of 12 weeks of multiple micronutrient supplementation on riboflavin, zinc, selenium, and copper biomarkers in Cambodian women of reproductive age.
  • Examining the diagnostic ability of multiple hematological indicators to predict responsiveness to iron supplementation in Cambodian women of reproductive age.
  • Determining the prevalence of sickle cell hemoglobinopathies, alpha-thalassemia, and glucose-6-phosphate dehydrogenase deficiency in children 6-59 months in the Democratic Republic of the Congo and associations between these disorders and each of hemoglobin concentration, iron status, malarial infection, and anthropometric measures.
  • Evaluating methods and the factors influencing hemoglobin measurement: the SPRING/USAID/PATH Hemoglobin Measurement (HEME) working group.
  • Validating the QuanSys Q-Plex™ Human Micronutrient ELISA for five nutrition and inflammation biomarkers: a collaboration with GroundWork Health.
