Mr John Findlay

BMedSci (hons) BMBS (hons) PhD FRCS

John is a Consultant Upper GI and Abdominal Wall Surgeon at North Devon District Hospital. He qualified from the University of Nottingham in 2007, awarded a First Class Honours BMedSci for research in molecular genetics and BMBS with honours. He trained in surgery in Oxford, and was appointed as a Consultant in North Devon in 2019. His particular clinical interests are gastro-oesophageal reflux disease and hiatus hernias, oesophageal dysmotility, laparoscopic hernia surgery and complex abdominal wall surgery. John is also Clinical Lead for Upper GI Cancer.

John’s doctoral and post-doctoral research at the University of Oxford focused on augmenting clinical decision-making in Upper GI Surgery using sophisticated modelling and machine learning of high resolution datasets, decision theory, and evidence-based surgery. He received his PhD for genomics and clinical informatics at the Wellcome Trust Centre for Human Genetics and the Department of Oncology, and was an Honorary Clinical Lecturer in Surgery, NIHR Oxford Biomedical Research Centre Senior Clinical Research Fellow in Oesophagogastric Informatics, Lecturer in Clinical Medicine at Corpus Christi College, and Surgical Tutor at the University of Oxford.

John has been awarded 12 international and national research prizes, published more than 60 peer-reviewed papers and book chapters, given over 60 international and national presentations and lectures, and is a Senior Editor at the International Journal of Clinical Practice. His current research focusses on improving clinical outcomes, processes and decision-making in Upper GI and abdominal wall surgery. John also has an interest in motorsport medicine and was a member of the Formula One® British Grand Prix Medical Team. He is a member of the British Hernia Society and Association of Upper Gastrointestinal Surgeons of Great Britain and Ireland.
