Dr. Miller directs the clinical nuclear cardiology laboratory at Yale-New Haven Hospital as well as the Cardiology Fellowship Program for the Yale University School of Medicine. His clinical and research interests center on the evaluation and treatment of infiltrative cardiomyopathies, particularly cardiac sarcoidosis and amyloidosis, and are focused on the role of nuclear cardiac imaging in diagnosing and defining treatment response in these disorders. In addition, Dr. Miller pursues translational research focused on metabolic cardiomyopathies, particularly the role of mitochondrial metabolism in obesity-related metabolic heart disease.
