About Ahmir Ahmad
Dr Ahmir Ahmad is a gastrointestinal endoscopist and luminal gastroenterologist at Welbeck, who was appointed to the consultant staff at St Mark’s Hospital in 2023. He is an experienced endoscopist with a particular interest in complex polypectomy, optical and AI-assisted diagnosis and advancing colonoscopy practice.
He completed his undergraduate training with distinction at University College London in 2010 and undertook a 4 year specialist clinical and research endoscopy fellowship at St Mark’s Hospital from 2018 to 2022. His PhD at Imperial College London involved a portfolio of research exploring “Efficiency in Colonoscopy” throughout the patient pathway under primary supervision of Professor Brian Saunders.
Findings from DISCARD3, a major study he led exploring optical diagnosis with a “resect and discard” strategy, are now being adopted nationally. As an expert advisor and committee member he is supporting implementation of optical diagnosis within the NHS England Bowel Cancer Screening Programme.
He has published widely, enjoys teaching and most recently co-authored the 8th edition of the classic textbook Cotton & Williams’ “Practical Gastrointestinal Endoscopy”.
