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.

  • We strive for diverse representation on our Advisory Council and balance in terms of expertise, gender and geography.
  • We strive to ensure opportunities for our collective members to give their best and grow professionally, to ensure that they do not face discrimination in their engagement with the collective and, subject to the terms of their contracts, to enjoy freedom of association and the effective recognition of the right to collective bargaining, to flexible working arrangements, a dignified workplace free of abuse of power and with zero tolerance for sexual harassment.
  • We are governed by the policies of University College London, which can be found here

GH5050 has a small team of 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.
