My research interests lie broadly in the area of vitamins. My specific research interests include folic acid and the prevention of birth defects, the consequences of high homocysteine, and the assessment of vitamin D status in various population groups.

Research Projects

Fish on Farms

The Fish on Farms project is being jointly conducted by the University of British Columbia (UBC) and Helen Keller International (HKI), with technical assistance from World Fish, in Prey Veng Province, Cambodia. This project, supported by IDRC and CIDA through the Canadian International Food Security Research Fund (CIFSRF), is studying how an integrated Homestead Food Production system will impact poverty, food security, and nutrition, particularly among women and children. This is the first project to rigorously measure the effectiveness of different models of Homestead Food Production at reducing undernutrition using biochemical and anthropometric measurements.

The Micronutrient Project

Our focus is on vulnerable populations, particularly women and young children, who bear the greatest burden of hidden hunger as deficiencies of key vitamins and minerals impact cognitive and physical development as well as reproductive health and productivity across the lifespan. We take an integrated approach to solutions with current projects ranging from small-scale aquaculture integrated with homestead food production in Cambodia, to home-fortification with Micronutrient Powders in Rwanda and other sub-Saharan African countries. Our interdisciplinary team has expertise in nutritional science, agriculture, gender, behaviour change communication, food science and related technologies, as well as experience in the development, implementation and evaluation of interventions.
