Dr. Daniels’ area of expertise is preventive cardiology, with a longtime interest in the application of sophisticated epidemiologic and biostatistical methods to pediatric clinical research problems. His studies have focused on better understanding the causes of blood pressure elevation and cholesterol abnormalities in children and adolescents, particularly the role that obesity may play in these health issues. He has also researched the development of structural and functional abnormalities in the heart and vascular system, including cardiovascular abnormalities occurring in pediatric patients with diabetes mellitus, as well as the relationship of left ventricular hypertrophy to obesity and hypertension. The role of lifestyle factors, such as diet and physical activity, is central to many of Dr. Daniels’ studies.

Dr. Daniels has served as Associate Editor for the Journal of Pediatrics since 1995. He is co-author of Medical Epidemiology, an introductory textbook for medical students, and co-author and editor of the book Pediatric Prevention of Atherosclerotic Cardiovascular Disease. In 2015, he was awarded the Gold Heart Award by the American Heart Association, which is the AHA’s highest volunteer honor. In 2020, Dr. Daniels was elected into membership in the American Association of Physicians and was formally inducted in 2021.
