Research Focus


My research focuses on the genetic basis of neurogenetic disorders with Quebec founder effects. It is focused on neuromuscular disorders. We have played an important role in the identification of the first mutations in the genes responsible for OPMD, HSANII, LGMD2L and TACH. Since 2002, I have become more involved in ataxia research. This continues to be an important part of my laboratory's research program and includes an extensive whole exome sequencing program in the context of the Genome Canada supported Care for Rare project. Since 2007, A very significant part of my work has been in close collaboration with the Fondation de l'Ataxie de Charlevoix-Saguenay as group leader of a CIHR new emerging team on rare diseases. My research program is therefore an integrative translational one, centered on genetic diseases more frequent in the population of Quebec.
