My academic interest is producing evidence to build systems for improved and equitable access to quality health care, particularly for cardiovascular diseases or conditions amenable to surgery (including trauma). I am particularly interested in the clinical and socio-economic consequences of providing these platforms of care. I am Professor of Global Health Research at Birmingham University, Visiting Prof at Wits University (South Africa), and Extraordinary Professor at Stellenbosch University. My research covers disciplines from epidemiology to qualitative research, health service assessment, predictive modelling, economics, and implementation science. I am privileged to have strong collaborative networks with colleagues in many institutes to help answer these questions.

I currently work with partners in Rwanda, Ghana, Sierra Leone, Burkina Faso, Malawi, Pakistan, and South Africa. In all of these projects, I work closely with local institutes and academics and ensure capacity building.

Publications include The Lancet Commission on Global Surgery, The Lancet Commission on Women and Health; I co-led The Lancet D&E Commission on Diabetes in sub-Saharan Africa. I have previously practiced as a medical cardiologist, worked as a freelance journalist, and was Editor in Chief of The Lancet Diabetes & Endocrinology.
