Joëlle was born in Utrecht, the Netherlands and grew up in French speaking Switzerland, where she obtained a B.S. in Psychology at the University of Lausanne, followed by a Master in Neuroscience at the University of Geneva. During her time at the University of Geneva, she worked on delineating structural grey and white matter development in 22q11 Deletion Syndrome, a genetic disorder associated with a high risk for psychosis. In her PhD at PennLINC, she is interested in using computational psychiatry approaches to decipher the mechanisms underlying brain development and the emergence of psychopathology. In her first project, she harnessed a data-driven approach to identify patterns of coordinated white matter development that support cognition. Next, she is interested in elucidating how sleep disruption impacts brain development and participates in the emergence of psychopathology during adolescence.
