CLINICAL INTERESTS: Dr. Padmanabhan is a cardiologist specializing in general cardiology. His specific interests include preventive cardiology, lamin A/C gene (LMNA) associated cardiomyopathies, and right heart disease in athletes. RESEARCH INTERESTS: Dr. Padmanabhan’s research focuses on understanding the gene-regulatory and epigenetic pathways that govern cell fate decisions during early cardiac development and cell state transitions in the pathophysiology of heart failure.
