I am a Clinical Epidemiologist and work part-time as a sessional GP in the NHS, and for a digital health provider. I have worked in global health as a clinician, researcher and implementer of innovative models of delivery to reduce health inequalities in Africa and Asia. I am currently leading a study exploring clustering of cardiovascular risk factor conditions in Zimbabwe.

I was Associate Trial Co-ordinator of the HPTN 071 (PopART) trial (2012-2019) which is the largest HIV prevention trial to date. It was a cluster randomised trial in 21 communities in Zambia and South Africa, with a total population of ~1 million and a research cohort of 42,000 individuals. We demonstrated that a 20-30% reduction in population HIV incidence was achievable using a ‘universal testing and treatment’ intervention. I was PI of two nested studies within the trial examining factors associated with uptake of trial interventions.

I previously worked for Medecins Sans Frontieres (MSF) HIV Advisor for MSF in Amsterdam and had oversight of several HIV programmes in Africa and Asia (2004-10). I was a member of MSF’s International HIV/AIDS Working Group which developed innovations to improve access to care for complex conditions in resource-limited settings, and worked with local teams on operational research to advocate for policy change in a number of countries.

My focus for the future is on improving access to care for cardio-metabolic conditions in low and middle income countries, evolving lessons learned from scale up of HIV care and using digital health where appropriate. -: CLEANED :-
