ARCH researchers work in close collaboration with individual, organizational and funding partners across Asia, Africa, the Middle East, Europe and North America. Our partnerships are guided by six Principles of Global Health Research put forward by the Canadian Coalition for Global Health Research. These principles emphasize that global health research aims to promote greater equity worldwide, and calls researchers to work in ways that support or reflect:

  • authentic partnership
  • inclusion
  • shared benefit
  • a commitment to the future
  • responsiveness to the causes of inequities and
  • humility.

In enacting these principles, ARCH researchers and their collaborators consider how all parties can equitably benefit from and contribute to research projects and how partners can be equitably positioned with respect to each other in research teams. ARCH collaborators intentionally work to be inclusive of populations historically marginalized. 

Please see our list of current and completed projects to learn more about specific ARCH collaborations.
