Anita joined the foundation in 2014 to lead a team focused on vaccine development for people in the poorest parts of the world, surveillance to identify and address causes of death in children in the most under-served areas, and significantly reducing the adverse consequences of diarrheal and enteric infections on children’s health in low and middle-income countries.

In those roles, she championed the creation of the foundation’s Maternal, Newborn, and Child Health Discovery & Tools program; the prioritization of HPV vaccination to prevent cervical cancer; and the creation of the Women Leaders in Global Health program—now called WomenLift Health—to promote diversity in global health leadership. She has led the Gender Equality division since November 2020.
