Stéphanie Lefebvre

Research Interests

Stéphanie Lefebvre is a Postdoctoral Researcher at the University of Southern California in the Neural Plasticity and Neurorehabilitation Laboratory. Prior to her position at USC, she completed a Bachelor’s Degree in Genetics and Biology from the University Claude Bernard of Lyon (France), a Master’s Degree in Biomedical Sciences from the University of Lausanne (Switzerland), and a PhD in Biomedical Sciences from the University Catholic of Louvain (Belgium): ‘Motor skill learning after stroke: exploration of neurophysiological mechanisms with functional neuroimaging and therapeutic modulation by non-invasive brain stimulation.’ She also completed a first Postdoctoral Fellowship at the University of Lille (France) and a second one at the CNRS, Lyon (France). Her main interests are mental health and brain plasticity, and specifically, how the brain reacts to changes in the environment during development or after a disease.
