Clinical and Research Interests

Dr. Chang’s clinical and research focus is on chronic kidney disease. She initially began her research from a basic science focus, looking at mediators of acute kidney injury and fibrosis in the kidney. She now focuses on the development and application of radiologic techniques applicable to patients with chronic kidney disease and all aspects of care related to chronic kidney disease.
