Greta Massetti is a public health scientist, educator, and lifelong advocate for using evidence to make the world safer for children and families. As Professor and Chair of the Department of Population Health Sciences at Georgia State University’s School of Public Health, she leads research on the epidemiology of violence and the connections between gender-based violence, infectious disease, and chronic illness.

Before joining GSU, Greta spent nearly two decades at the U.S. Centers for Disease Control and Prevention (CDC), where she led global initiatives to prevent violence, overdose, and suicide. She directed the Violence Against Children and Youth Surveys (VACS), working closely with partners like WHO, UNICEF, PEPFAR, and Together for Girls to help countries build data systems that drive policy change and strengthen community safety.

Greta founded the INSPIRE Evidence Lab to bring together scientists, students, and practitioners who share a belief that data can—and should—be used for good. Her vision is to build a global hub for innovation, mentorship, and collaboration in violence prevention, grounded in rigorous science and inspired by hope.

Greta studied psychology and music at Northwestern University before earning her M.A. and Ph.D. in clinical psychology from Stony Brook University. Outside of work, Greta loves spending time with her family, hiking, reading for pleasure, taking care of her cats, and supporting the thriving Atlanta arts community.
