Research Interests

Dr. Jiang’s research focuses on pediatric nutrition, specifically on absorption and biological roles of bioactive components in human milk, such as lactoferrin and osteopontin. She uses both cell models and animal models to investigate mechanisms by which milk derived bioactive compounds are absorbed and exert their multiple functions. In addition, she is interested in dynamic changes of milk bioactive components throughout lactation in human populations, as well as relationships between the changes and the health outcomes.
