Biographical details

Associate Professor Gareth Denyer currently works in the areas of molecular biology and genetics, and nutrition and metabolism, and was appointed Deputy Head of School under the guidance of current Head of School, Professor Iain Campbell. Gareth did his undergraduate degree at the University of Oxford and stayed there to do a PhD under the supervision of Professor Sir Philip Randle. He was appointed as a Lecturer in Metabolism, in the Department of Biochemistry in 1990. He was the recipient of the University Excellence in Teaching Award in 1995, and was part of the ELATE Committee that won the group award in 2010. In 2012, he won the Australian Society for Biochemistry and Molecular Biology Teaching Award. He has over 70 publications over a wide range of discipline areas including metabolic regulation, microarray analysis, glycemic index testing, nutritional analysis, and molecular biology.

Research interests

Gareth main interest is in the molecular mechanisms underlying body 'set point'. He uses DNA microarrays to look at transcriptome patterns in circumstances of metabolic interest- for example:

  • how does gene expression change in different tissues when we consume different diets - especially those of different glycemic index?

  • how do different hormones (like insulin and leptin) affect which genes are switched on and off?

  • what gene expression patterns characterise large and small adipocytes? What happens as adipocytes change in size (as in weight loss and weight gain).

  • what gene expression patterns characterise different types of obesity?

To assist with the interpretation of microarray data, he has developed user-friendly analysis tools, and these are widely used by collaborators across the world. He also has interests in the regulation of intermediary metabolism, nutritional epidemiology and fuel selection during exercise. He is a consultant for the weight loss industry and helps manage Glycemic Index testing services. In addition he is an enthusiastic database developer and has created systems for:

  • Dietary communication and meal analysis for the Sydney 2000 Olympic Games

  • Sydney University Glycemic Index Research Services and Metabolism and Obesity services at Royal Prince Alfred Hospital.

  • Clinical Research in both Research Institutes and Hospitals

  • Dietary assessment and nutritional intervention studies (especially in the area of childhood obesity and on-line shopping)

  • Course management and University Administration
