    Dr. Bernadette Boden-Albala, MPH, DrPH A social epidemiologist whose work examines the intersection of a number of important disciplines including vascular epidemiology and behavioral and social science. Her research initially utilized the rich prospective database of the Northern Manhattan Study (NOMAS) as she examined issues of race-ethnicity, and social resources/health disparities including isolation, educational attainment, nativity, acculturation, health care utilization, language, and literacy. Her research is specifically related to health disparities, stroke, and vascular disease with an emphasis on the identification of novel modifiable stroke risk factors, and the promotion of behavioral change for primary and secondary stroke prevention.
