Dr. Nicolas Dumont obtained his PhD at the Université Laval where he studied the regulatory network between inflammatory cells and skeletal muscles. He did his post-doctoral training at the Ottawa Hospital Research Institute in Dr. Michael Rudnicki’s lab, where he studied muscle stem cell defects in Duchenne Muscular Dystrophy. Dr. Dumont became an assistant professor at the Université de Montréal in 2016, and he established his lab at the Sainte-Justine hospital research center. His research program is divided in 3 axes: 1) characterizing the intrinsic mechanisms regulating muscle stem cell fate decision during myogenesis, 2) characterizing the impact of rare genetic variants on muscle stem cell function, and 3) investigating novel therapeutic avenues targeting defective muscle stem cells to mitigate muscular dystrophies. Dr. Dumont holds a FRQS Junior-2 award, and his lab is funded by grants from the CIHR, NSERC, ThéCell network, Stem Cell Network, Orphan disease center, AFM-Telethon, and Muscular Dystrophy Canada.
