I studied maths and applied statistics for my BA and MSc and then completed a PhD in the epidemiology of HIV in rural Zimbabwe at Imperial College London. I then moved to LSHTM to be based full-time in Johannesburg, South Africa for seven years at the Aurum Institute working on TB and HIV. I moved back to the School in July 2012, where I continue to work on TB projects in South Africa, China and Peru, as well as health systems strengthening studies in Zambia and Burkina Faso.

Teaching

I am co-organiser of the Advanced Statistical Methods in Epidemiology module on the Distance Learning MSc in Epidemiology. I also teach on the face-to-face and distance learning modules on the Evaluation of Public Health Interventions. 

Research

The primary focus of my research is the evaluation of large, cluster randomised trials in TB control and health systems strengthening. These investigate the impact of:

  • medication monitors on TB adherence in China;
  • a socioeconomic support package, delivered to TB affected families, on TB control in Lima, Peru;
  • household point-of-care CD4 testing and household delivered isoniazid and cotrimoxazole preventive therapy on linkage to HIV care and preventive therapy completion in TB affected households in South Africa;
  • a health systems strengthening intervention on child and adult mortality and health system coverage in Lusaka, Zambia;
  • an e-health solution to improve adherence to Integrated Management of Childhood Illnesses guidelines in Burkina Faso.
