Martin Landray


Professor of Medicine and Epidemiology

  • Research Director, Health Data Research UK
  • Deputy Director, Big Data Institute

Prof Landray’s work seeks to further understanding of the determinants of common diseases through the design, conduct and analysis of efficient, large-scale clinical trials and prospective cohort studies (including UK Biobank). He has led a series of major clinical trials assessing treatments for cardiovascular and kidney disease. These have enrolled over 65,000 individuals, producing results that have changed regulatory drug approvals, influenced clinical guidelines and changed prescribing practice to the benefit of patients.

He is heavily involved in efforts to streamline clinical trials, working with regulatory agencies to facilitate efficient and cost-effective trials. He is a member of the Steering Committee of the FDA Clinical Trial Transformation Initiative, leading the Monitoring, Quality by Design, and Mobile Clinical Trials projects. He is a member of the NHS Digital Research Advisory Group and the NICE Data & Analytics External Reference Group, and leads the 21st Century Clinical Trials programme for Health Data Research UK.

Prof Landray completed medical training at University of Birmingham (UK) and specialist training in Clinical Pharmacology & Therapeutics, and General Internal Medicine at University of Birmingham. He continues to practise clinical medicine as an Honorary Consultant Physician in the Cardiology, Cardiac and Thoracic Surgery Directorate at Oxford University Hospitals NHS Trust. He is a Fellow of the Royal College of Physicians of London, the Higher Education Academy, the British Pharmacological Society, and the European Society of Cardiology. He was knighted in 2021 for services to public health and science.
