About Us

MSF Analysis is a platform for the dissemination of material on the politics of health and humanitarianism provided by the Médecins Sans Frontières (MSF) Analysis Department based in the Operational Centre Brussels as well as from guest contributors. This website is intended to stimulate reflection and debate on humanitarian topics organised around the themes of migration, refugees, aid access, health policy and the environment in which aid operates.

While the views expressed on this website do not necessarily reflect the official position of MSF, they are based on analysis derived from the organisation’s experience working in over 70 countries worldwide.

Contributions to this website are primarily made by a core group that works in reflection, analysis and advocacy with the MSF Operational Centre Brussels. This group – profiled below – also makes up the informal editorial committee that receives guest contributions.
