The Cardiovascular Biology Division is made up of over thirty faculty members from basic science and clinical departments with the goal of training students for careers as independent investigators studying the molecular and cellular aspects of cardiovascular physiology and disease. One of the medical triumphs of the latter half of the twentieth century is the remarkable advancement that has been made in the diagnosis and treatment of heart disease. Despite these advances, cardiovascular disease still remains the most common fatal and disabling disorder in the United States. Over the last two decades we have made tremendous progress in our understanding of the molecular aspects of biology. Now we have the opportunity to use these new and powerful molecular tools to explore complex biological systems.
