Research Interests

Dr. Darshan S. Kelley is a research chemist with the Western Human Nutrition Research Center. Dr. Kelley is interested in studying the effects of diets on inflammation and immune responses. The focus of his studies has been the modulation of risk factors for cardio-vascular disease and insulin resistance by dietary fatty acids and phytonutrients. He is also interested in the effects of fatty acids on cell growth, differentiation and apoptosis.
