Dr. Marks brings a number of different techniques to the catheterization laboratory, such as radial artery catheterization, in which a small artery in the wrist, rather than one in the leg, is used to introduce the tools used to diagnose and treat some forms of coronary artery disease. Additional techniques include non-invasive angiography and septal modification.

Dr. Marks' research interests include cardiovascular disease and health in members of various races, left ventricular hypertrophy, and physician characteristics and new technology as they affect the outcomes after coronary interventions. His efforts help understand the adaption and diffusion of new technology. He is intimately involved in therapies to treat diseases of the mitral and aortic valves without surgery. He completed an advanced interventional cardiology fellowship at the Mayo Clinic in Rochester, MN, and an internal medicine residency, and cardiology fellowship, at the Brigham and Women's Hospital/Harvard University in Boston, MA.
