In 2003 he was the first in Adelaide to train in capsule endoscopy and then in 2007 the first in Adelaide to train in balloon enteroscopy both of which remain essential tools for investigating and treating small intestinal disease. He has published in multiple peer review journals and presented at conferences at a national and international level.
