I am mixed-methods researcher at the London School of Hygiene and Tropical Medicine (LSHTM) working on the health determinants, systems and policies in transitional settings, particularly those affected by armed conflict and forced migration. This has focused principally on mental health and non-communicable diseases. I have worked on studies with conflict-affected populations in Lebanon, Ukraine, Georgia, northern Uganda, South Sudan, and the Democratic Republic of Congo. As Principal Investigator, I have received over £16 million in research funding from funders including the Wellcome Trust, GCRF/UKRI, ESRC, European Commission, DFID, and USAID.

I was Editor-in-Chief of the BMC journal Conflict and Health from 2011 to 2021, and I am on the Editorial Board of Refugee Survey Quarterly. I was the Guest Editor for the journal of Migration and Health’s series in internal displacement and health (2021-2022), and Guest Editor for the Lancet series on public health in humanitarian crises (2017). I was a funding panel member of the R2HC humanitarian health research funding scheme (2016 to 2022). I am on the Board of Directors for the NGO the International Alliance for Diabetes Action (IADA).
