Leadership
 

After finishing his medical training at McGill University, Mathieu moved to Toronto to learn Paediatrics and Nephrology at Toronto’s SickKids before moving to Yale University to pursue a Ph.D. under the guidance of Dr. Richard Lifton. There, he focused on gene discovery for rare pediatric kidney diseases. This work led to the discovery of two novel forms of atypical hemolytic-uremic syndrome. He then returned to SickKids, joining the Division of Nephrology, the Cell Biology program at the SickKids Research Institute, and the Department of Biochemistry at the University of Toronto.

Much of his work in the lab and clinic focuses on rare genetic diseases affecting the kidneys of children, including glomerular, cystic, metabolic and tubular conditions.
