Research Programs




Jacob Vorstman was trained to become a psychiatrist (2008) and a Child & Adolescent Psychiatrist (2009) at the University Medical Center Utrecht. He defended his PhD thesis at the University of Utrecht / Rudolf Magnus Institute of Neuroscience in 2008 on the genetic and psychiatric aspects of the 22q11.2 deletion syndrome.  Currently, he combines his clinical work at the department of psychiatry with several ongoing research projects in the field of the genetics of autism and schizophrenia.

From 2004 to 2006 he worked in the Genetics lab of Prof. Dr. B. Emanuel, Division of Human Genetics and Molecular Biology at the University of Pennsylvania. He learned the practical and analytical aspects of molecular genetic research using different methods (FISH, PCR, MLPA, Real-time PCR, RNA expression) on genetic material from 22q11DS patients. Concurrently, h worked at the Department of Child en Adolescent Psychiatry of the Children’s Hospital of Philadelphia where  he has set up a child psychiatry outpatient clinic for 22q11DS patients.

Gradually he has broadened the scope from 22q11DS to a wider perspective; the role of structural genomic abnormalities in autism and schizophrenia and trying to advance our understanding of the genetic architecture underlying these disorders. 

Currently, he is the PI of a research lab at the Brain Center Rudolf Magnus, his team includes a post doctoral fellow, a research assistant, a PhD student and several master students. To date he has supervised four PhD students towards a successful defense of their thesis. He is the PI of two large, funded, genetic studies in autism and schizophrenia. In addition Dr Vorstman is an executive board member in an international consortium for the study of the behavioral phenotype in the 22q11.2 deletion syndrome. This consortium encompasses 22 research sites en is funded by the NIMH (12M US Dollar). One of his strengths is his combined experience; he succesfully integrates his research tasks at the Brain Center with a clinical appointment as a child and adolescent psychiatrist at the University Medical Center Utrecht. Over the past years he has been fortunate to develop close and productive collaborations with many investigators in the genetics of psychiatric disorders across the world.
