Joan Schall Ph.D.

Dr. Joan Schall received her PhD in Biological Anthropology from the University of Pennsylvania in 1991. She has been the Associate Director of the Nutrition and Growth Laboratory at Children's Hospital of Philadelphia (CHOP) since 2000, conducting studies in growth and nutrition of children with chronic disease. Her research prior to CHOP, included studies of the antecedents of adolescent hypertension, health effects of migration and modernization (field work in Papua New Guinea), growth and nutrition during teenage pregnancy and effects on outcomes. Her current research interests over the past two decades are in areas of nutrition-related health, growth, body composition abnormalities, and energy balance studies in healthy children and those with chronic disease including: cystic fibrosis, sickle cell disease, cerebral palsy, Crohn disease, epilepsy, congenital heart disease, and HIV/AIDS. Dr. Schall has over 30 years of experience collecting and supervising research quality growth and body composition measurements of children and adults. She has been a Co-Investigator for numerous NIH-sponsored and CFF-sponsored grants over the last 16 years investigating the nutrition and growth status, energy expenditure, bone health, and malabsorption of children with cystic fibrosis. Specific to cystic fibrosis research, Dr. Schall was Co-Investigator for the completed NIH-sponsored clinical trial for supplementation of Lym-X-Sorb, a novel organized lipid matrix to correct the metabolic and physiological abnormalities associated with fat malabsorption, essential fatty acid and choline deficiencies in children with cystic fibrosis (NIH/NIDDK (SBIRII): PI for Clinical Site: Stallings). She is also currently co-investigator for the Investigator Initiated Study (Vertex Pharmaceuticals: PI: Stallings) investigating weight gain and energy balance in subjects with CF gating mutations before and after treatment with Ivacaftor. She is also currently co-investigator for the Investigator Initiated Study (Abbvie, Inc.: PI: Zemel, Lead Investigator: Stallings), investigating the diagnosis of pancreatic-based malabsorption in subjects with chronic pancreatitis before and after use of pancreatic enzyme medication. Dr. Schall plays a broader role in the health and nutrition community, serving since January 2010 as the Expert Anthropometry Consultant (“Gold Standard”) for the National Health and Nutrition Examination Survey (NHANES) and the National Youth Fitness Survey (NYFS). In this capacity, she is responsible for training, conducting reliabilities, and maintaining quality assurance for the Body Measurement component of both NHANES and NYFS.
