Dr Graham Radford-Smith is a Group Leader at QIMR Berghofer. In addition he is also a fulltime senior clinician at the Royal Brisbane and Women’s Hospital, with major clinical (Inflammatory Bowel Disease (IBD) and Parenteral Nutrition) and administrative (Pre-eminent senior staff specialist, Deputy Director) roles in the running of the Gastroenterology Department and the delivery of IBD services to Metro North, Wide Bay and Central Queensland. He is currently chair of the Luminal Sub-Committee of the Statewide Clinical Network for Gastroenterology (Qld) and on the steering committee.

Dr Radford-Smith’s major research interests include: the inflammatory bowel diseases (Crohn’s disease, ulcerative colitis); the utilisation of health information to optimise patient care and patient outcomes; and, the role of the gut in human disease. Dr Radford-Smith is a passionate advocate for the optimisation of patient outcomes and how we as a healthcare community can best utilise, audit and research to optimise clinical practice. Working with his team, he has developed an efficient translational model for Gastroenterology research facilitated by the proximity of QIMR Berghofer to the hospital clinics. In addition he has played a lead role in the development and maintenance of bespoke software to help run both clinical and research programmes as interconnecting circuits. Dr Radford-Smith’s scientific expertise crosses several disciplines as evidenced by his publication record of over 170 articles to date in the field of gastroenterology.

Dr Radford-Smith is also chair of both the ANZ IBD Consortium and the registered charity, Crohns Colitis Cure. Previous, he was president of the Gastroenterology Society of Queensland, past member of the Australian IBD association’s executive committee and the Gastroenterology Society of Australia’s research committee. Graham has also served as the chair of the phenotype subcommittee of the International IBD Genetics Consortium and remains a member of the management committee.

  • role of the microbiome in health and disease
  • impact of SLC39A8 on the human microbiome
  • development and clinical testing of a colonoscopy triage tool to optimise the triaging of patients into the appropriate prioritisation category (waiting list)
  • development of a simple diagnostic algorithm for high risk Crohn’s disease for primary care physicians
  • development of a new algorithms to determine response to intravenous corticosteroids in subjects presenting with acute severe colitis



Most recently Dr Radford-Smith and his team designed a simple clinical tool to assist Gastroenterologists in triaging patients referred for a colonoscopy. The Gut Health laboratory have commenced recruitment of a second cohort to further establish this tool and improve its accuracy. A second study out of this work will be presented at international meetings this year. This work focuses on the relationship between biomarkers and the microbiome in the non-diseased state, identifying for the first time an important biological link between a known susceptibility gene for Crohn’s disease and a discrete microbiome signature. Much of the research is now focussed on the utility of big data, including big clinical datasets. The first published example of this has addressed the dynamic natural history of Crohn’s disease in a paper entitled “A rolling phenotype in Crohn’s disease”. It challenges a pre-existing static model of Crohn’s disease phenotype. They have also played a lead role in a study across Australia and New Zealand analysing the efficacy of the anti-TNF medications, infliximab and adalimumab, in the treatment of patients with refractory Crohn’s disease. One of the key findings is the important role played by concomitant thiopurine therapy. This is one of the largest and most detailed real-life studies published to date and provides clinicians with important practical advice in the use of these biologic therapies.
