My objective is to improve health at individual and global levels, an objective I am able to pursue in my current positions as Editor in Chief of The Lancet Diabetes and Endocrinology and as a professor at King’s Centre for Global Health, KCL. My main interest is in diabetes, its interactions with other conditions, and its clinical and socio-economic consequences in Lower and Middle Income countries – especially in sub-Saharan Africa. I am also interested in improving data collection for health system planning and ensuring access to surgical care for people living in LMICs. I have been closely involved with The Lancet Commission on Global Surgery and The Lancet Commission on Women and Health. I am currently working on The Lancet Diabetes & Endocrinology Commission on Diabetes in sub-Saharan Africa. I have a background in medical research, in particular in the clinical diabetes and cardiovascular fields and I have previously practiced as a medical cardiologist. I have lectured around the world on the topic of good research practice, health care metrics, and translating research into practice. As well as working as an editor, clinician, and researcher, I have been a freelance journalist and worked as a scientific advisor to the BBC. I hold degrees in Forensic Medicine and Medical Law, Medicine, and Zoology; an MD in Clinical Pharmacology; a performance diploma (ABRCM); and am also a Member of the Royal College of Physicians of London. In my spare time, I try (unsuccessfully) not to fall off horses and play the violin in a chamber music setting.
