Amit Garg

Associate Scientist

Amit Garg is the Associate Dean, Clinical Research, at the Schulich School of Medicine & Dentistry, Western University, has practiced as a staff nephrologist at the London Health Sciences Centre in London, Ontario, Canada since 2003, and is a Professor of Medicine, Epidemiology and Biostatistics at Western University, with a cross-appointment in the Department of Health Research Methods, Evidence, and Impact (HEI) at McMaster University. A past president of the Canadian Society of Nephrology, Amit Garg serves as the current Ontario Lead of the Kidney, Dialysis and Transplantation Program at ICES.

He values his ongoing collaborations with PJ Devereaux and other leading clinician-scientists at PHRI, which has led to several sub-studies funded by the Canadian Institutes of Health Research which examined the effects of perioperative interventions on the risk of acute kidney injury (off-pump cardiopulmonary bypass surgery) in the CORONARY study, and more. A current interest is in pragmatic randomized trials embedded into routine healthcare delivery.

Amber Molnar

Associate Scientist

Amber Molnar is a nephrologist at St. Joseph’s Healthcare in Hamilton, and Assistant Professor, Department of Medicine, Division of Nephrology, McMaster University.

She holds a Kidney Research Scientist Core Education and National Training (KRESCENT) program’s New Investigator Award through CIHR and the Kidney Foundation of Canada. Amber earned her M.D. at the University of Saskatchewan followed by internal medicine training at Western University, and completed her nephrology and MSc (Epidemiology) training at the University of Ottawa.

David Collister

Associate Scientist

David Collister is a nephrologist at the University of Alberta Hospital and Assistant Professor in the Department of Medicine, Division of Nephrology, at the University of Alberta. He completed a PhD in Health Research Methodology at McMaster University and research fellowship at the Population Health Research Institute (PHRI) focused on run-in periods and patient oriented research in kidney disease including the DISCO-RLS trial.

His research program focuses on symptom management in patients with kidney disease and, in particular, randomized controlled trials of therapies to alleviate symptoms in chronic kidney disease and dialysis. He currently holds a Kidney Research Scientist Core Education and National Training (KRESCENT) New Investigator Award. His research program is funded by the Canadian Institutes of Health Research and the Kidney Foundation of Canada. He is the principal investigator of RESET-DIALYSIS, a prospective cohort study of patients with advanced chronic kidney disease initiating dialysis which will examine the responsiveness of uremic symptoms to dialysis and uremic symptom pathophysiology with metabolomics, proteomics and genomics. He is the principal investigator of DISCO-POT, a randomized controlled trial of nabilone versus placebo for the treatment of uremic pruritus in adults with kidney failure treated with dialysis. He is also interested in the intersection between transgender, non-binary and gender diverse populations and kidney disease.
