Biography summary

George was born and raised in Athens, Greece where he initially pursued studies in music, taught classical guitar at the Conservatory and fullfiled the mandatory military service (special forces alumni: rank commando). 

He moved to the UK in 2004 to pursue studies in Molecular Biology and Biochemistry (BSc) and Neuroscience (Hons) at the University of Surrey, where he investigated the nuclear translocation of the PER3 polymorphic variant circadian clock proteins within the suprachiasmatic nucleus.

In 2007, he accepted an MRC scholarship to pursue research in Structural Biology and Molecular Biophysics at the prestigious MRC-Laboratory of Molecular Biology at the University of Cambridge. During his tenure there he used nuclear magnetic resonance spectroscopy, x-ray crystallography and cryoelectron microscopy to investigate the structure of the hepatitis C virus internal ribosomal entry site. 

He first came to Australia in 2009, to undertake research in regenerative medicine and stem cell biology at the University of New South Wales. He was named the inaugural Miltenyi Biotec Australia scholar, and embarked to investigate the cellular and molecular mechanism underpinning functional muscle tissue regeneration following allotransplantation of adult satelite cells into a damaged muscle bed.

He completed a Master in Nutrition and Dietetics at The University of Sydney. At the same time he represented Australia in Powerlifting, winning the world championship in his weight division in 2014, while setting 11 national records in the process. 

He completed a PhD in Science at The University of Sydney in which he reported on the access to and effectiveness of dietetic services for people with type 2 diabetes in Australia.

He has published collaborative research with researchers from universities in Australia, Europe and the US and he has written several policy and perspective manuscripts published in official journals including the official journal of the American Geriatrics Society, of Sports Medicine Australia, of the American College of Sports Medicine, of the British Dietetic Association, and of the Dietitians Association of Australia.

George is currently undertaking an Executive Dean Health Research Fellowship in the Institute for Physical Activity and Nutrition (IPAN), in the School of Exercise and Nutrition Sciences, Faculty of Health at Deakin University. During this Fellowship, he is conducting a series of epidemiological analyses to elucidate the junction between non-communicable and communicable diseases with the ultimate objective to inform public health policy and clinical practice.

Elucidating the junction between chronic and communicable diseases:

  • Obesity and metabolic syndrome and adverse outcomes from chronic and communicable diseases
  • Adipose tissue as an immune system-regulating organ
  • Hyperglycaemia and the immune system
  • The immunomodulatory role of individual nutrients, dietary patterns, and diet
  • How does the type, duration and intensity of physical activity affect the immune system's function
  • The ageing immune system. The differential effect of biological vs chronological ageing on the function of the immune system.
