Professor, Biostatistics

Alexa Beiser
(617) 638-5140
72 E. Concord St Robinson (B)


Alexa Beiser has been on the faculty at Boston University School of Public Health since 1985, engaged in teaching and collaborative public health research; she co-directed the biostatistics program from 2000-2004, and is currently Associate Chair for Education. She formerly taught and now coordinates the sections of Introduction to Statistical Computing. For more than twenty years, Dr. Beiser has been the lead biostatistician for the Framingham Heart Study neurology group, examining clinical and sub-clinical neurological outcomes including MRI measures of brain structure, cognitive performance, dementia, Alzheimer’s disease, stroke, Parkinson’s disease, and seizures. Decades of examining risk factors for neurological diseases has naturally led to studying factors associated with accelerated brain aging. She has coauthored Framingham publications relating risk factors including midlife vascular factors, plasma homocysteine, plasma leptin levels, cardiac index, red blood cell omega-3 fatty acids, metabolic dysregulation, visceral fat, air pollution; serum brain-derived neurotrophic factor; and insulin-like growth factor 1, to measures of brain aging. Dr. Beiser also has made use of the richness of the multigenerational Framingham data to examine temporal trends in prevalent and incident neurological disease and to relate documented parental dementia and stroke to offspring stroke, cognitive performance and MRI measures of brain structure.
