Alana Brennan

Alana Brennan, PhD, MPH, is an associate professor in the Department of Global Health at Boston University School of Public Health, with a secondary appointment in epidemiology. She received both her MPH and PhD in epidemiology from Boston University. Her research focuses on the epidemiology and prevention of diabetes and cardiometabolic disease, examining how clinical, social, and environmental factors shape disease progression and health outcomes. Her NIH- and American Heart Association-funded research spans diabetes care and treatment outcomes, cardiometabolic complications among people living with HIV, and environmental influences on cardiometabolic health in South Africa and the United States. She also studies Food Is Medicine interventions to address food insecurity and improve cardiometabolic health in underserved populations. Her research is expanding to examine diabetes heterogeneity—including subtypes and longitudinal disease trajectories—and its implications for Alzheimer’s disease and related dementias (AD/ADRD).
