He is also pursuing a PhD in Health Research Methodology

Research Interests

Dr. Michael Walsh's research interests include:

  1. the epidemiology of acute kidney injury, particularly in the perioperative setting
  2. the epidemiology of acute glomerulonephritis
  3. clinical trials in both acute kidney injury and acute glomerulonephritis
  4. clinical trial methodology
He is a member of the European Vasculitis Research Group EUVAS and the Population Health Research Institute. Dr. Walsh's research is funded by the Canadian Institutes of Health Research, National Institute of Health Research, Food and Drug Administration, National Health and Medical Research Council, and the Canadian Centre and Network for Trials Internationally. He is the co-principal investigator of the PEXIVAS trial and the Remote IMPACT trial and leads a large prospective cohort study in perioperative acute kidney injury.
