Harsha Thirumurthy, PhD, an associate director of Penn’s Center for Health Incentives & Behavioral Economics (CHIBE), and Alison Buttenheim, PhD, MBA, interim director of CHIBE, have received a three-year, $3.5 million grant from the Bill and Melinda Gates Foundation to establish a first-of-its-kind HIV-focused nudge unit in South Africa. The nudge unit will form partnerships with government and HIV services providers and test behavioral interventions to increase population-level coverage of HIV prevention services. The project will be led by CHIBE with a strong local partner, HE2RO (Health Economics and Epidemiology Research Office at Wits University in Johannesburg).
