I trained in Medicine at the University of Cape Town, did doctoral work at the University of Wales College of Medicine, and studied Clinical Epidemiology at The University of Toronto.  I was appointed Professor of Primary Care in the Nuffield Department of Primary Care Health Sciences at the University of Oxford in 2013.


My research focuses on common infections (especially the appropriate use of antibiotics,  antibiotic resistance, point of care testing,  and treatments for viral infections), and health care communication and behaviour change (co-author of Motivational Interviewing in Health Care). I have published~400 papers with a H-Index of >50. Our PACE Study won the Royal College of General Practitioners Research Paper of the Year Award in 2020.

I have led or helped lead  > 20 randomised clinical trials, and In the space of 12 months, published first-author trials in the world’s top three general medical journals

  • The PACE study of biomarker guided antibiotic prescribing for acute exacerbations of chronic obstructive airways disease in the New England Journal of Medicine
  • The ALIC4E 13 country trial of antiviral treatment for influenza like illness in The Lancet
  • The PRICESS Trial of probiotics to reduce antibiotic use and prevent infections in care home residents in the Journal of the American Medical Association. 


I have supervised 12 doctoral students to successful completion and currently supervise 5 doctoral students.
