Biography

Ron Wald is a nephrologist at St. Michael’s Hospital and Director of the hospital’s Hemodialysis Program. He is a Professor of Medicine at the University of Toronto. A native of Montreal, he completed his undergraduate and medical degrees at McGill University and continued his clinical training in internal medicine and nephrology at the University of Toronto. Following this, he completed his Master of Public Health at Harvard University and a research fellowship at Tufts Medical Center in Boston. Dr. Wald’s research areas are critical care nephrology and maintenance dialysis. He was co-principal investigator of the STARRT-AKI trial, a Canadian Institutes of Health Research-funded international trial on the timing of dialysis initiation in critically ill patients with acute kidney injury. He is also interested in fluid management in the setting of acute kidney injury and the long-term outcomes of patients who survive an episode of acute kidney injury. In the realm of maintenance dialysis, he is on the leadership team of the multinational PHOSPHATE trial that is evaluating whether intensive lowering of serum phosphate reduces the risk of major adverse cardiovascular events.

Please note: Dr. Wald is not taking any summer students.
