Medical Advisory Committee

Coeliac Australia is advised by a Medical Advisory Committee (MAC), made up of Australia’s leading gastroenterologists, coeliac disease researchers, immunologists, dietitians and medical practitioners.

The advice we receive from the MAC is based on current research and ensures we remain informed on up to date best practice for diagnosis and management of coeliac disease. It also allows us to fulfil our commitment to provide our members with the most current and relevant information on all matters relating to coeliac disease and the gluten free diet.

The following members make up our Medical Advisory Committee.


Dr Jason Tye-Din

Dr Tye-Din is a gastroenterologist and coeliac disease specialist. He has worked closely with Coeliac Australia for the past decade and is actively engaged in medical and public education on coeliac disease. He leads the Coeliac Research team at Walter and Eliza Hall Institute, where his research has contributed to understanding the toxicity of gluten and provided the basis for designing new coeliac diagnostics and treatments. He practises at The Royal Melbourne Hospital, and is a lecturer at Melbourne and Monash Universities. He consults to ImmusanT Inc, the company developing the coeliac immune therapy.


Dr Bob Anderson

Dr Anderson initially trained as a clinical specialist in gastroenterology and internal medicine. His work in gastroenterology and immunology, working with vaccines, and coeliac patient care gave him a better understanding of the medical problems of unrecognised coeliac disease, the limitations of gluten free living, and the potential of vaccines that might be applied to coeliac disease. Dr Anderson’s first research in coeliac disease identified the component of wheat gluten responsible for much of the immune reaction causing coeliac disease. He also spent ten years at the Walter and Eliza Hall Institute establishing a research program focussed on defining the specific targets of the immune response to gluten as a means to designing new diagnostic tests and therapies. He worked with Dr Jason Tye-Din to establish Coeliac Clinics, foster education campaigns, and expand coeliac disease research in Australia. Dr Anderson initiated the Australian New Zealand Coeliac Research Fund with The Royal Melbourne Hospital and co-founded the Coeliac Research Fund with Coeliac Australia. He later co-founded and became Chief Executive Officer of Nexpep Pty Ltd, to begin the preclinical and initial clinical development of Nexvax2, known as the coeliac vaccine. After ImmusanT Inc (USA) acquired Nexpep's technology, he moved to New England to serve as Chief Scientific Officer for ImmusanT, Inc. in Cambridge MA and continues his involvement in the development of Nexvax2 as it progresses through clinical development.
