Lisa Mosconi leads the Women's Brain Initiative research program at Weill Cornell Medical, where she also serves as associate director of the Alzheimer's Prevention Clinic, the first of its kind in the United States. For as long as she can remember, she wanted to be a brain scientist -- and as she witnessed her grandmother and her two sisters spiral into dementia, her motivation grew stronger. Mosconi now dedicates her entire career to studying brain health, and how it plays out differently in women than in men.
