Meet the Collective & Advisory Council

Global Health 50/50 works to bridge the gap between evidence and organisational and policy change through its unique operating model. Our collective brings together academic researchers, medical doctors, political strategists, communication experts and gender advocates, alongside an esteemed Advisory Council of influential champions and policy makers. 

You can read more about our workplace values and policies here.

GH5050 has a small team of full- and part-time staff, supported by a passionate global network of members. To limit the potential for conflicts of interest, collective members affiliated with organisations reviewed by GH5050 are not engaged in reviewing or coding organisations that they work for or advise.
