Willa Brenowitz, PhD, MPH

Core Faculty
Center for Population Brain Health

I am an epidemiologist and I am broadly interested in understanding factors that contribute to brain aging. I am especially interested in the role of multimorbidity in cognitive decline, as well as the intersection of genetic, psychosocial, and health factors across the lifecourse. I am also interested in using novel statistical and epidemiologic approaches to study AD and other chronic diseases in aging.
