Physician-scientist at Duke University
Ravi Karra is a Duke physician-scientist whose work links advanced heart-failure care with cardiac regeneration and sarcoidosis research. He is an Associate Professor of Medicine and Pathology, an Affiliate of the Duke Regeneration Center, and a Member of the Duke Cancer Institute. His laboratory studies interactions between cardiac endothelial cells and cardiomyocytes during growth and disease, while his clinical interests include heart-failure recovery and cardiac sarcoidosis. Karra earned an M.D. from Duke University School of Medicine in 2005 and completed internal-medicine residency at Brigham and Women’s Hospital from 2005 to 2008. Earlier Duke roles included Medical Instructor in Cardiology and Assistant Professor of Medicine and Pathology. He also helped form the interdisciplinary team that became Duke’s sarcoidosis Center of Excellence.
