I am an Honorary Clinical Research Fellow in Public Health Medicine at Imperial, and a Specialist Registrar in Public Health in London. I divide my time between academic research and service public health work - most recently as a Health Adviser at the UK Department for International Development (DFID).

My research interests lie primarily in health policy and systems research (HPSR) in the UK and internationally, with a special focus on the Middle East and North Africa. I have a particular interest currently in understanding how health systems adapt (or otherwise) to acute and chronic stressors including those arising from armed conflict and large-scale population movements. The main focuses for this work are:

1. Communicable disease surveillance and control

2. Health workforce regulation, training and development

3. The political economy of health policymaking and implementation.

Before qualifying in medicine, I worked in policy analysis for RAND Europe, the Institute for Government, and the Nuffield Trust.
