Senior Research Officer
After completing a BSc degree in Nutritional Sciences at the Hebrew University (Israel) in 1992, Samocha-Bonet joined the Nutrition and Dietetics Department at Tel Aviv Medical Center as a clinical dietician. In 1996 she completed a MSc in Clinical Biochemistry at Tel Aviv University (Israel).
As a clinical dietician, Samocha-Bonet came to terms with the fact that only a minority of her patients could maintain a reduced healthy weight in the long term and she decided to turn to research into obesity and metabolic disease. After the birth of her second child, she embarked on a PhD in medical science.
After completing a PhD in Physiology and Pharmacology at Tel Aviv University (Israel, 2006), she relocated to Sydney where she took a postdoctoral position at the Diabetes & Metabolism Division at the Garvan Institute of Medical Research (2007). In 2011 she was awarded the Skip Martin Early Career Fellowship from the Australian Diabetes Society.
In 2013, she established the Clinical Insulin Resistance group at the Garvan Institute.
