Dr. Crystal Karakochuk is an Assistant Professor in the Faculty of Land and Food Systems at UBC. Her research program focuses on the links of nutritional status and anemia, including the role of nutritional supplementation and of hemoglobinopathies in children, women, and families in Canada and globally.

Her research lab performs comprehensive measurement and interpretation of indicators of anemia (hematological and nutritional biomarkers) and genetic polymorphisms associated with hemoglobin in individuals, families, and populations. She also studies the benefits and potential harms of nutrition supplementation policies and programs designed to treat anemia, including untargeted iron and folic acid supplementation in women and children globally.

The innovative aspect of her research program is that it combines two distinct fields of research – nutrition and hematology. This unique program brings together clinicians, researchers, and policy makers to advance and apply knowledge in nutritional hematology. Dr. Karakochuk’s research program addresses two key objectives:

  • To improve diagnostic methods and investigate new biomarkers for anemia and iron deficiency for individual- and population-level assessment
  • To evaluate the risk-benefit of Canadian and global micronutrient supplementation policies to advance clinical practice and to inform safe, effective nutrition therapy worldwide

FNH 455: Applied International Nutrition: The aim of this course is to provide a critical examination of nutrition interventions in the global health context. Students are required to actively participate in discussions and to work in teams to apply learned knowledge and complete an international nutrition intervention proposal.

FNH 470/475: Foundations of Nutrition Care I & II (co-instructed with Heather Woodward): This course focuses on the etiology and pathophysiology of and nutrition therapy for selected diseases and conditions, and skill development related to the Nutrition Care Process. The course is restricted to students in year 4 of the Dietetics Major.
