Dr Andrew Betik

BSc Hons (University of Waterloo), MSc (University of Waterloo), PhD (University of Calgary)

Research Fellow, Institute for Health and Sport, College of Sport & Exercise Science

Dr Andrew Betik is a postdoctoral research fellow working for the Institute of Sport, Exercise & Active Living (ISEAL) with joint appointments in the Colleges of Health & Biomedicine and Sport & Exercise Science.

Andrew obtained his MSc from the University of Waterloo in Cardiorespiratory Physiology, and then his PhD 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, his current projects are investigating the role of nitric oxide in facilitating glucose uptake in diabetic muscle and the potential benefits of tocotrienols to improve fat metabolism.

Andrew has ongoing collaborations with:

  • Professor Andrew McAinch, Associate Professor Michael Mathai, Associate Professor Alan Hayes (VU, College of Health & Biomedicine)
  • Professor Glenn McConell (VU, IHES)
  • Dr Erik Hanson (University of North Carolina, USA)
  • Professor Steve Rattigan and Dr Michelle Keske (Menzies Research Institute, Tasmania)
  • Professor Erick Richter, Professor B Kiens, Dr Kim Sjoberg, Dr Lykke Sylow (University of Copenhagen).
