Research Projects

I have lectured and presented widely in Australia and overseas in the areas of: the causes of obesity, effects of obesity on people at different stages in their life cycle, impact of overweight and obesity during pregnancy and how being above a healthy weight can affect the physical and emotional wellbeing of children and adolescents. Furthermore, I lectured to healthcare professions and lay people about the different treatment options available to help those living with overweight and / or obesity.

I travel extensively to research new and improved methods of treatment and have been a demonstrator of gastric band adjustments and demonstrating effective communication skills whilst consulting with people living with overweight or obesity.

I have a particular interest in the effects of overweight and obesity on female and male fertility, pregnancy and outcomes to the next generation.

I have been a regular presenter at a number of RACGP conferences, medical obesity scientific meetings, bariatric surgical conferences, lifestyle conferences and integrated allied health conferences/ workshops  over the past decade.

I have been involved in surgical research for many years through the metabolic and bariatric Unit at St George Private Hospital. Sydney. I am currently engaged in some exciting research looking at the role of combination therapy in those individuals who have experienced a partial response to bariatric surgery.

I have published papers  and/ or articles in various GP, medical and bariatric surgery forums.
