I am a Professor of Global Child Health at Imperial, a Consultant in Paediatric Infectious Diseases at St. Mary's Hospital in London and an Associate Professor at Stellenbosch University. I divide my time between Cape Town and London. Clinical work includes the care of children with complex infectious diseases and my major area of research is that of children with tuberculosis.
I studied medicine at Corpus Christi College, Cambridge and Imperial College London and have carried out paediatric training in both the UK and Australia. Before clinical academia, I was an infantry officer in the British army, worked as a doctor for Médecins Sans Frontières in Côte d'Ivoire and spent time on an expedition in Patagonia. I undertook my PhD in Cape Town, studying drug-resistant tuberculosis in children, and have gained Diplomas in Tropical Medicine and Paediatric Infectious Diseases. During 2017 I spent six months at the Department of Global Health and Social Medicine in Harvard University on a Fulbright Scholarship evaluating different strategies to combat drug-resistant tuberculosis in children.
Between 2018 and 2022 I was funded through an MRC Clinician Scientist Fellowship to evaluate correlates of risk in children exposed to multidrug-resistant tuberculosis.
