Research Interests

Dr. Chang is a practicing nephrologist and Assistant Professor in the Kidney Health Research Institute at Geisinger Health System. He completed residency, fellowship, and a Masters in Clinical Research Methods at Loyola University Medical Center, followed by a post-doctoral Renal Epidemiology fellowship at Johns Hopkins. He has received research awards from the American Heart Association, the National Kidney Foundation, and a K23 Career Development Award from the National Institute of Diabetes and Digestive and Kidney Diseases (Morbid Obesity, Bariatric Surgery, and Kidney Function). His research focuses on improving our understanding of the effects of diet and obesity on risk of kidney and cardiovascular disease through epidemiologic and interventional research studies. A second area of research focuses on health system interventions to identify and optimize management of early kidney disease and hypertension.
