Since joining the Division of Aging in 2005, Dr. Djoussé's national and international reputation has continued to grow. His research is focused on nutrition and genetic factors, and the interaction between both on the risk of cardiovascular disease. Over the past decade, Dr. Djoussé's work has contributed to our understanding of the role that diet and other modifiable factors play on the risk of hypertension, coronary heart disease, stroke, diabetes, and heart failure, primarily using major epidemiologic cohorts such as the Framingham Heart Study, the NHLBI Family Heart Study, the HyperGen Study, the Physicians' Health Study, the Cardiovascular Health Study, and the Women's Health Study. His work has also advanced our knowledge of the burgeoning field of gene-environment interactions, particularly as they relate to the intake of moderate alcohol consumption and cardiovascular disease. His recent work has demonstrated beneficial effects of a healthy diet and moderate alcohol consumption on the risk of hypertension, heart failure, and diabetes.

Dr. Djoussé is a fellow of the American Heart Association.
