BSc. (Hons) (University of Waterloo), MSc. (University of Waterloo), PhD (University of Calgary), Exercise and Muscle Physiology
Research Fellow, Institute of Sport, Exercise and Active Living
Dr Andrew Betik is a postdoctoral research fellow working for the Institute of Sport, Exercise and Active Living (ISEAL) with joint appointments in the Colleges of Health and Biomedicine and Sport and Exercise Science.
Andrew obtained his M.Sc. from the University of Waterloo in Cardiorespiratory Physiology, and then his Ph.D. from the University of Calgary (Exercise and Muscle Physiology) looking at the role of exercise in old age to induce mitochondrial biogenesis and prevent the age-related decline in muscle aerobic capacity.
Andrew has a diverse background in applied and basic physiology, with specific strengths in muscle metabolism and exercise using rodent models in disease states such as aging, diabetes and obesity. Specifically, current projects investigate the role of nitric oxide in facilitating glucose uptake in diabetic muscle and the potential benefits of tocotrienols to improve fat metabolism.
Current supervision team:
- Professor Glenn McConell
- Associate Professor Michael Mathai (VU)
He also has ongoing collaborations with:
- Dr Erik Hanson (VU)
- Associate Professor Alan Hayes (VU)
- Muscle Research Group (Prof S Rattigan and Dr M Keske) (Menzies Research Institute, Tasmania)
