Biography

Ron Wald is a nephrologist and Associate 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 a Master in Public Health at Harvard University and a research fellowship at Tufts Medical Center in Boston. Since joining the St. Michael’s Hospital Division of Nephrology in 2006, Dr. Wald has been responsible for the hospital’s acute dialysis program. In addition to attending on the hospital’s Nephrology consult and ward services, he provides longitudinal care for patients on chronic hemodialysis and has an active general nephrology practice.

Dr. Wald’s research interests are in the areas of critical care nephrology and chronic dialysis. He is currently leading a Canadian Institutes of Health Research-funded international trial on the impact of the timing of dialysis initiation on survival in critically ill patients with acute kidney injury. He also has a strong interest in the long-term outcomes of patients who survive an episode of acute kidney injury and is co-leading a trial that is comparing specialized nephrology care vs usual care in this population. In the chronic dialysis area, Dr. Wald co-led a CIHR-funded study on the cardiovascular benefits of incentre nocturnal hemodialysis. He recently completed a multicentre pilot trial examining the implementation of two different levels of serum phosphate control in the hemodialysis population. A larger definitive trial to evaluate whether intensive serum phosphate lowering mediates improved clinical outcomes is planned. As a founding member of the Kidney Dialysis and Transplantation Program of the Institute for Clinical Evaluative Sciences, Dr. Wald is also involved in several studies that are using province-wide administrative data to answer research questions in kidney disease.

Please note: Dr. Wald is not taking any summer students in 2018.
