Our collective

Global Health 50/50 (GH5050) aims to bridge evidence and policy change through a unique model that brings together a collective of researchers, strategists, communicators, and advocates, alongside an advisory council of influential champions and policy makers.

A few of our core staff members are funded to work on GH5050 part-time. However, GH5050 is largely staffed by volunteers affiliated with other organisations. These include: University College London, UNAIDS and the Embassy of Sweden in Lusaka. To limit the potential for conflicts of interest, collective members affiliated with organisations reviewed by GH5050 (i.e. UNAIDS and SIDA) are not engaged in reviewing or coding any institutional policies.

GH5050 is funded by the Wellcome Trust and an anonymous philanthropist.
