Maretha de Jonge studied child psychology (orthopedagogiek) at the University of Utrecht. She completed her clinical training as a child psychologist in health care at the University Medical Center Utrecht before completing her Ph.D. in 2006. Her Ph.D. research focused on behavioral and neurocognitive endophenotypes of autism spectrum disorders.

As a clinical psychologist / cognitive behavioral therapist and an assistant professor, she has a keen interest in developmental disorders, with emphasis on autism and on selective mutism. Her research focuses mainly on neurocognitive and behavioral characterization of autism as a genetically defined developmental disorder. She is engaged in international collaborative research projects: the International Molecular Genetic Study of Autism Consortium (IMGSAC), the Autism Genome Project (AGP) and the Innovative Medicines Initiative (IMI).

As a registered international trainer in the Autism Diagnostic Interview (ADI-R) and the Autism Diagnostic Observation Schedule (ADOS) she contributed to the research on the psychometric properties and utility of these instruments in the Dutch population.

She is interested in the use of applied gaming in health care. She developed the online behavioral therapy program for selective mutism ( which includes a webportal and an applied game.
