Dr. Susan S. Percival

Professor & Chair

Dr. Percival’s research program focuses on enhancing immunity by dietary components with an emphasis on a specific immune cell, the γδ-T cell. Her lab investigates individual compounds, such as L-theanine, ellagic acid and quercetin; foods such as mushrooms, cranberry juice, grapes and grape juice; and botanicals or mixtures of other compounds that are found in dietary supplements such as aged garlic extract. Using both human subjects and cell culture models we are learning about the mechanisms by which immunity is modified by diet. The goal is to improve immune function while reducing damaging effects associated with chronic inflammation.

Because of the demands of her administrative position, Dr. Percival is not taking on many graduate students at this time.
