Peng Ji, Ph.D.

  • Assistant Professor, Department of Nutrition
  • Assistant Nutritionist in Agricultural Experiment Station
Perinatal period is a critical window of brain development that is featured with robust neuronal growth as well as greater vulnerability to environmental insults. I am interested in evaluating the opportunities and the risks of nutritional factors in modulating neuronal resilience to early-life adverse events (e.g. infection and stress). Domestic piglet is used as translational model of human infants in our studies. We utilize molecular techniques, behavioral tests, disease-challenge models to integrate pathophysiology, neuroimmunology and cognition. In this way, we are able to evaluate how diet induced peripheral “signals” (e.g. metabolites and humoral profiles) exert their function in central nervous system during health and disease.
