Bess L. Caswell, Ph.D., M.S.

  • Postdoctoral Scholar, Department of Nutrition
Dr. Caswell's research interests include assessment of child diet in low- and middle-income countries, food-based nutrition interventions and connections between agriculture, food security and child nutrition. She has worked on research studies relating to biofortification of staple crops in Bangladesh and Zambia, developed a tablet-based tool for conducting 24-hour dietary recalls and studied child dietary adequacy and diversity across agricultural seasons among Zambian children.

  • Junior Specialist, Department of Nutrition
Katherine's research is focused on maternal and child nutrition and health in resource-poor communities. Specifically, Katherine is interested in studying: socio-economic, cultural, and environmental determinants of maternal and child nutrition and health; infant and young child feeding practices, including complementary feeding; and relationships between diet, child growth and development.

Guy-Marino Hinnouho, M.D., Ph.D.

  • Postdoctoral Scholar, Department of Nutrition
Dr. Hinnouho’s research interests involve the implementation of community-based randomized controlled trials in the field of Nutrition and Infectious Diseases and the impact evaluation of health programs in low-income countries.

Gilberto Kac, Ph.D.

  • Professor, Department of Nutrition, Federal University of Rio de Janeiro, Brazil
Dr. Kac's research program comprises projects on maternal and child nutrition with emphasis on (1) the association of nutritional biomarkers on maternal mental health and perinatal outcomes; (2) human milk bioactive compounds and it's effect on infant growth and development; and (3) consequences of inadequate gestational weight gain on maternal and child outcomes.

Arox Kamng'ona, Ph.D.

  • Postdoctoral Scholar, Department of Nutrition
Dr. Kamng’ona received his B.S. (honours) in Chemistry from the University of Malawi, Malawi and his B.S. (honours) in Molecular Biology from The University of Cape Town, Cape Town, South Africa. He received his M.S. in Molecular Biology form the University of Cape Town, Cape Town, South Africa. He received his Ph.D. in Infection and Immunity from the University of Liverpool, Liverpool, United Kingdom. He is currently working as a postdoctoral scholar examining the effects of a lipid-based nutrient supplement (LNS) on Malawian infants gut microbiota, as well as the association between microbiota and subsequent infant outcomes (growth, development, morbidity and inflammation). His broad interests are in understanding the human microbiota and impact on human health in resource poor African settings.

Sika M. Kumordzie

  • Postdoctoral Scholar, Department of Nutrition
Dr. Kumordzie’s research interests are in the areas of life cycle nutrition i.e. the effects of poor nutrition and improved nutrition through supplementation on women of childbearing age, pregnancy and birth outcomes, child growth, and risk of later chronic disease in developing country settings; improving local food systems and quality of diet in low and middle income countries; nutrition transition and health outcomes; and quantitative methods for nutritional assessment.

Hanqi Luo, Ph.D.

  • Postdoctoral Scholar, Department of Nutrition
Dr. Luo's research interests include Maternal and Child Nutrition; Micronutrient Deficiency; Cost Effectiveness Analysis; Epidemiological and Mathematical Modeling; and Nutritional Epidemiology

Jody Miller, Ph.D.

  • Project Scientist, Department of Nutrition
Dr. Miller’s research interests focus primarily on investigating the causes and consequences of nutrient deficiencies with an overall aim to develop and test nutritional strategies to improve health in vulnerable populations, particularly low-income groups and the elderly. Current research projects include investigating Vitamin A intake and status and markers of health of Filipino infants receiving multiple food and supplement vitamin A fortification strategies (Glovitas Study), and improving the protein and micronutrient intakes of institutionalized elderly in New Zealand rest homes (NZ-NAPs Study).

Harriet Okronipa

  • Postdoctoral Scholar, Department of Nutrition
Dr. Okronipa’s research interests are mainly in the area of maternal and child nutrition and health. Her specific research interests include: infant feeding practices and their impact on child growth and risk of overweight; taste and food preferences in children and adults, and their impact on dietary practices and health outcomes; programs or interventions to reduce the consumption of sweet snacks and sugar-sweetened beverages especially among low income communities; micronutrient interventions; and interventions to reduce undernutrition and overnutrition especially in low income settings.

Sarah Zyba, Ph.D.

  • Postdoctoral Scholar, Department of Nutrition
Dr. Zyba has conducted research on zinc metabolism and exploring novel methods for zinc nutrition assessment as well as evaluating zinc absorption from a lipid based nutrient supplement. Currently, Dr. Zyba is working on a project to develop an adherence marker for tracking consumption of nutrient supplements.
