Research
Dr Leong's research interests include clinical drug trials, inflammatory bowel disease epidemiology and biomarker discovery, and advanced endoscopic imaging including confocal laser endomicroscopy. He is widely published in these fields including in the top ranked specialty journal Gastroenterology. Dr Leong has been awarded prestigious research grants, fellowships and prizes including from the National Health and Medical Research Council (NHMRC) of Australia and Gastroenterological Society of Australia.
"My research aims to find simple, translatable and cost-effective solutions to common gastrointestinal problems and to develop preventative measures or early detection through screening."
Clinical drug trials
Dr Leong is principle investigator for several multi-centre clinical drug trials mostly in inflammatory bowel diseases at Concord and Macquarie University Hospitals. These trials are approved by the Human Research Ethics Committee and certified on clinicaltrials.gov. Please discuss with me if you are interested in participating.
