Josianne earned her BSc in Health Biochemistry from the University of Sherbrooke in 2022 and completed her MSc in Biochemistry at the Université de Montréal in 2024. During her graduate studies in Dr. Serge McGraw’s lab, she focused on the neurodevelopmental and epigenetic effects of DNMT3A mutations in a mouse model of Tatton-Brown-Rahman Syndrome. She is broadly interested in uncovering the molecular and epigenetic mechanisms underlying neurodevelopmental disorders, a passion that led her to begin her PhD in 2025. Outside the lab, Josianne enjoys playing softball, skiing, cooking, and spending time relaxing on the beach.
