MyselfI am a research fellow at the Overseas Development Institute (ODI) in London, where I am part of the Social Protection and Social Policy team.

Prior to joining ODI, I was a postdoctoral research fellow at Nuffield College at the University of Oxford. In addition, I have consulted for the World Bank, OECD, and the Global Fund, and I have been visiting scholar at Harvard, Oxford, and the World Bank Development Research Group.
