My research interests are in health economics relating to developing countries. In particular:

  • Applying quasi-experimental methods to evaluate large scale health programs
  • Randomised controlled experiments of behavioural economics interventions to improve uptake and adherence to efficacious HIV prevention methods
  • Cost-effectiveness analysis of population-level health care delivery interventions

Current projects

I am currently using field experiments in Zimbabwe to measure the influence of risk, time and social preferences on risky sexual behaviour, uptake of HIV testing and prevention methods; two randomised controlled trials to improve uptake of PrEP and VMMC. This project is being implemented through the Manicaland Centre for Public Health Research.

I am also evaluating the cost-effectiveness of Population Effects of Antiretroviral Therapy to Reduce HIV Transmission (PopART) in Zambia and South Africa, one of the largest HIV trials offering universal testing and treatment in sub-Sahara Africa.
