Sridevi Krishnan, Ph.D.

  • Assistant Project Scientist, Department of Nutrition
Dr. Krishnan's current research focuses on combating (prevention and management) cardiovascular disease, type 2 diabetes, and obesity in women by exploring dietary, exercise and lifestyle habits, especially focused on personalizing changes to optimize health solutions. In addition, she is also interested in phenotypic differences in the manifestation of disease pathogenesis, especially in identifying them using -omic (metabolomic, proteomic, genomic, glycomic and microbiome) tools.

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.

  • Research Chemist, USDA ARS Western Human Nutrition Research Center
  • Adjunct Professor, Department of Nutrition
Dr. Keim’s research program involves validation and application of body composition methodologies, evaluation of the effects of dieting and physical activity on energy expenditure in overweight and obese individuals, and, more recently, development and application of tools to assess appetite, food preferences, and dietary patterns in humans.

Malay K. Mridha, Ph.D.

  • Assistant Project Scientist, Department of Nutrition
Dr. Mridha’s research interests include the role of polyunsaturated fatty acids in pregnancy and lactation; weaning and complementary feeding practices and their association with growth and illness of children; the linkage between infection and nutrition; evaluation of existing nutrition intervention programs for women and children; nutrition and non-communicable diseases; and mainstreaming nutrition into health system.
