Dr. Gaziano received his MD from Yale Medical School and his MPH from the Harvard School of Public Health. He is a Professor of Medicine at Harvard Medical School and is the Chief of the Division of Aging at Brigham and Women’s Hospital.

In addition, Dr. Gaziano serves as the director of the Geriatric Research and Education Center (GRECC) at the Boston Veterans Administration Healthcare System. He is also co-director of MAVERIC, which is one of three national centers of epidemiology funded by the Department of Veterans Affairs.

Dr. Gaziano is principal investigator for the ongoing Physicians' Health Study (PHS) II study, a large-scale trial of vitamins in the prevention of chronic disease. His research interests include the roles that individual lifestyle choices (diet, exercise, smoking), metabolic factors (obesity, high cholesterol, and hypertension), and biochemical and genetic markers play on the risk of coronary artery disease and stroke. Also of interest is the impact that vascular disease has on other organ systems, including cognitive dysfunction and renal disease.

Recently, Dr. Gaziano has initiated a number of research projects to investigate the diverse nature of atherosclerosis. While atherosclerosis plaques form only in certain large and medium-sized vessels, the process of atherogenesis affects arteries of all sizes. For example, cognitive decline and osteoporosis-related fractures have been linked to various cardiovascular disease risk factors, suggesting a role for small vessel disease in vascular dementia and in abnormal bone remodeling. These projects are intended to explore the extent to which atherosclerotic disease in small vessels leads to these and other chronic conditions, such as renal failure.
