After earning his bachelor’s degree in Food Sciences (Université d’État d’Haïti), Dr. Dort was awarded several international scholarships to pursue a master’s degree at the Université Catholique de Louvain, in Belgium, and a PhD at Université Laval, in Canada. Following his Ph. D, he worked as a nutrition consultant for several international non-profit organizations, such as HarvestPlus, which implement programs to enhance food security in Haiti. Then, Dr Dort completed a postdoctoral training at the CHU Sainte-Justine Research Center in Dr Nicolas Dumont’s lab, where he investigated therapeutic compounds that target inflammation and muscle stem cell dysfunction with the goal of treating muscular dystrophies. His research was supported by fellowships from the Muscular Dystrophy Association and AFM-Telethon
