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.
