My research focuses on conducting pragmatic evaluations of health system innovations across a range of disease areas and geographies. The primary evaluation methodologies I have applied have been cluster randomised trials and stepped wedge trials, always in interdisciplinary teams. I currently work on projects in Peru, Burkina Faso, India, China and Pakistan. I lived in Johannesburg for seven years and I have also worked on projects in Zimbabwe and Zambia. Before joining LSHTM I completed a PhD in Epidemiology at Imperial College London, an MSc in Applied Statistics at the University of Oxford and a BA in Mathematics at the University of Cambridge.

Teaching

I am co-organiser of the Advanced Statistical Methods in Epidemiology module on the Distance Learning MSc in Epidemiology. I teach on the face-to-face and distance learning modules on the Evaluation of Public Health Interventions. I also teach randomised controlled trials methodology on the LIDC short course in Evaluation of Development Programmes.

Research

Examples of projects that I work on are:

  • A stepped-wedge trial of an e-health solution to improve adherence to Integrated Management of Childhood Illnesses guidelines in eight districts of Burkina Faso, with embedded realist evaluation and cost-effectiveness analysis;
  • A cluster randomised trial of medication monitors to improve TB adherence among ~3000 TB patients in China, with embedded cost-effectiveness analysis;
  • A cluster randomised trial of a socioeconomic support package, delivered to TB-affected families, to improve TB control among 32 communities in Peru;
  • An impact and process evaluation of the Indian Government’s peer educator programme to improve adolescent health in two states, with embedded cost-effectiveness analysis;
  • A stepped-wedge trial of a health-systems strengthening intervention, including quality improvement cycles in clinics and strengthening community health workers, to reduce child and adult mortality in 42 districts in Zambia.
