Tonie's areas of expertise include evaluation of multiple birth defects and/or developmental issues and interpretation of clinical testing results. 

She received her medical degree and postdoctoral training in medical genetics from Jefferson Medical College, Philadelphia, PA., and clinical cytogenetics and molecular training at the Johns Hopkins University School of Medicine, Baltimore, Md. 

She is also a Fellow of the American Academy of Pediatrics and a Founding Fellow of the American College of Medical Genetics. 

Sylvia is a clinical supervisor of the specialist training program at Prinsenstichting and a teacher at the Erasmus University Medical Centre, Rotterdam. She did a PhD on Self-injurious Behaviour in Cornelia de Lange syndrome. 

She works at Prinsenstichting, at the Amsterdam Expertise Centre for Neurodevelopmental Disorders (including Cornelia de Lange syndrome) at the Amsterdam University Medical Centre, and at the Centre for Consultancy and Expertise (CCE). 

She is a Physician for Individuals with Intellectual Disabilities (AVG). She received her specialist training at the Prinsenstichting and at the Erasmus University Medical Centre, Rotterdam. 

Chris is currently researching early intervention of behaviour disorders in people with severe intellectual disability and autism spectrum disorder, behavioural phenotypes in genetic syndromes and neuropsychological and behavioural assessment for people with severe intellectual disability. 

He is Professor of Neurodevelopmental Disorders and Director of the Cerebra Centre for Neurodevelopmental Disorders at the University of Birmingham.

He was trained as a clinical psychologist at Edinburgh University before completing a PhD on self-injurious behaviour in people with intellectual disability at the Institute of Psychiatry, London. 

Paul specialises in assessment of children and adults with severe and complex autism spectrum disorders, especially supportive communication, social-emotional functioning, sensory information processing and cognitive development in children and adolescents with autism spectrum disorders. 

He is behavioural specialist at Autism Team Northern-Netherlands, Jonx, the child- and adolescent psychiatry service of Lentis Psychiatric Institute in Groningen. 

He did his PhD on "Cognition, self-injury and autism in Cornelia de Lange Syndrome: their mutual relationships and genetic background.” 

She was trained as a psychiatrist in Amsterdam and continued her training as a child and adolescent psychiatrist, including a residency in Clinical Genetics. 

She received her medical degree at Groningen University.

From 2006 to date Inge has been employed as Medical Director at Autism Team Northern-Netherlands, Jonx, the child- and adolescent psychiatry service of Lentis Psychiatric Institute in Groningen.
