Susan J. Zunino, Ph.D.

  • Adjunct Professor, Department of Nutrition
Dr. Zunino’s lab is interested in how phytochemicals regulate immune response. Obesity increases the risk of developing viral and bacterial infections compared to normal weight individuals. The focus of the laboratory is to understand how dietary phytochemicals may modulate the innate immune response to decrease the risk of infection in the obese.

Rachel E. Scherr, Ph.D.

  • Assistant Researcher, Department of Nutrition
Dr. Scherr’s research interests are mainly focused on nutrition education and promotion in school-aged children. Research efforts include the implementation of a multi-component, school-based intervention entitled the Shaping Healthy Choices Program. Additionally, Dr. Scherr is focused on the usage of sub-clinical and novel biomarkers in nutrition education to assess the effectiveness of these multi-component interventions
