Taryn J. Smith, Ph.D.

  • Postdoctoral Fellow, Department of Nutrition
Dr. Smith’s research interests include more fully understanding the effects of nutrition on health outcomes in population groups at risk of nutritional deficiencies, particularly infants, children, adolescents and pregnant women, and nutritional interventions and public health strategies targeted at these population groups to improve health and nutritional status and to avoid deficiencies.

Haiying Yuan

  • Postdoctoral Scholar, Department of Nutrition
Dr. Yuan's research interests focus on understanding how children develop social and language skills, and how to measure these underlying abilities using statistical modeling, such as item response theory models and structural equation models.

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.
