Dr. Crystal Karakochuk is an Assistant Professor in Human Nutrition in the Department of Food, Nutrition, and Health at UBC and an Investigator at the BC Children’s Hospital Research and Women’s Health Research Institutes.
Dr. Karakochuk’s research program focuses on micronutrients and human health. She evaluates programs and policies for anemia prevention and treatment, and the risk-benefit of micronutrient interventions in children and women. Her research brings together clinicians, researchers, and policy makers to advance and apply innovative knowledge in human nutrition.
Over the next five years, Dr. Karakochuk’s research will address two key objectives:
- To evaluate the risk-benefit of Canadian and global micronutrient interventions to advance clinical practice and inform safe and effective nutrition policy.
- To improve diagnostic methods and evaluate novel biomarkers for anemia and iron deficiency for individual- and population-level assessment.
Dr. Karakochuk’s laboratory is based at the Food, Nutrition and Health building. She established the infrastructure required to conduct high-throughput work in a high-precision facility, and created a facility to advance analytical methods in nutritional hematology. She employs randomized controlled trials as her core methodology which provide the most rigorous design to provide reliable evidence on the effectiveness of interventions. Ultimately, her research yields to important policies that target health, social, and economic benefits to children, women and families.
