Associate Professor John Dixon is an academic general practitioner
with a clinical background in rural general practice prior to taking a
research interest in obesity in 1997. In 2009 he was awarded a
prestigious NHMRC Senior Research fellowship. His major interests are
in exploring the many dimensions of the obese state, translating
findings into practice and advocating for better services for those
with this chronic disease.

Known internationally for his research and education programs,
his background in primary care has enabled a diverse examination of
the problems and diseases related to severe obesity. His generalist
approach has enabled research across specialist boundaries and he is a
respected leader nationally and internationally in endocrine, liver,
respiratory, obstetric, psychological and other research into obesity
and the effects of weight loss on these related conditions. His
research is valued by both surgeons and physicians alike, bridging the
gap in communication between advances in surgery for weight loss,
metabolic research, clinical practice and evidence base medicine. He
has championed a multidisciplinary approach to the assessment and
management of these important conditions. He has published widely and
has over 120 peer reviewed journal articles. These include the first
randomized controlled trial of bariatric surgery for weight loss in
diabetes published in JAMA in 2008 and a citation classic published in
Gastroenterology in 2001 on the predictors of non-alcoholic
steatohepatitis and liver fibrosis in the severely obese. He is an
editor of the Handbook of Obesity Surgery: Current Concepts and
Therapy of Morbid Obesity and Related Diseases, published in 2010.

A study demonstrating the effects of gastric banding on satiety
stimulated his interest in exploring the mechanisms of action of
bariatric surgery in animal models and has led to projects with the
Department of Physiology at Monash University and collaborations with
global researchers.

John is the immediate past president of the Australian and
New Zealand Obesity Society, an executive member of the Obesity
Surgeons Society of Australia and New Zealand and is on both the
scientific and program committees of American Society for Metabolic and
Bariatric Surgery as a physician member. He is one of the 20-member
International Diabetes Surgery Task Force (IDSTF), a nonprofit
organization with diverse expertise in diabetes, obesity surgery,
gastroenterology and clinical trials development. He is an associate
editor of both Obesity Surgery and SOARD.
