Dr Meghan Leaver


Experienced health systems scholar and public sector special advisor, who led the development of a novel qualitative framework used to analyse millions of patient comments.

Before co-founding PEP Health, Meghan directed several key AI strategy and implementation projects in coordination with the UK central government and the NHS. Meghan is also a Senior Health Systems Researcher at the University of Oxford’s Nuffield Department of Medicine, where her research focuses on patient safety, human factors and the contextual factors that underpin the delivery of safe and effective care.

PEP Health was founded by Dr Alex Griffiths and Dr Meghan Leaver. Having spent many years evaluating patient safety and quality improvement interventions globally they became frustrated by the mismatch between the data and what inspectors were finding.

Working closely with health systems in the UK and abroad, Dr Meghan Leaver generated a novel theoretical framework for extracting behavioural safety insights from text data, which provided the conceptual framework for themeing patient comments at scale.

By combining their expertise and skills in quality improvement and data science, Alex and Meghan built a first of its kind, scalable, real-time solution for listening to patients which proved an accurate measure of patient experience.
