Welcome to my website!

I’m an Assistant Professor of Health Economics at the London School of Economics in the Department of Health Policy. I am also an Honorary Lecturer in the Department of Infectious Disease Epidemiology at Imperial College London.

My research interest is in the economics of public health practice with a focus on optimising resource allocation decisions. This includes theoretical economic work on financing health system strengthening and identifying sustainable and equitable allocation rules for international donors. Applied economic projects evaluating the impact of health interventions and reforms through experimental and non-experimental methods, and the cost-effectiveness of population level health system interventions.

With funding from the National Institute of Mental Health (NIMH), USA, I am currently leading field experiments in Zimbabwe to measure the influence of risk, time and social preferences on risky sexual behaviour and two randomised-controlled trials to improve uptake of pre-exposure prophylaxis (PrEP) and voluntary medical male circumcision (VMMC).
