Dr. Klein is an Instructor of Pediatrics in the Division of Pediatric Gastroenterology, Hepatology, and Nutrition. Dr. Klein's research focuses on developing and implementing targeted nutritional interventions to prevent and treat malnutrition across the lifespan in people with sickle cell disease in low- and high-income settings. She completed a Vanderbilt-Emory-Cornell Duke Fogarty Global Health fellowship in Accra, Ghana, west Africa, focused on the risk factors for low birth weight in infants born to mothers with sickle cell disease. During her clinical fellowship, she helped lead a randomized controlled trial for children with sickle cell disease and severe acute malnutrition in Nigeria. Before her time at Vanderbilt, Dr. Klein participated in research and clinical experiences in Kenya, South Africa, and Tanzania. Dr. Klein plans to submit a career development award to build upon this work to improve the treatment of children with sickle cell disease and malnutrition.
