Research Programs


Bob Oranje is vice director of NICHE, University Medical Center Utrecht (UMC-U), Holland, as well as senior researcher and head of the psychophysiological department of the Center for Neuropsychiatric Schizophrenia Research [CNSR], Glostrup, Denmark. Since 2009 he is lector at the Faculty of Health and Medical Sciences, Dept. of Neurology, Psychiatry, and Sensory Sciences, Copenhagen University, Denmark. Furthermore, since 2012 he is UHD at the department of Psychiatry, UMC-U, Holland, where he opened a new electrophysiological and neurocognitive lab in 2017. BO has developed a psychophysiological test-battery, the Copenhagen Psychophysiological Test Battery [CPTB]. The CPTB consists of five psychophysiological paradigms specifically designed for research on psychiatric disorders and plays a central role in the projects that he has initiated. His research primarily focusses on improving/developing medical treatment for patients with schizophrenia, autism and ADHD. Secondary goals are developing animal models for schizophrenia and determining vulnerability indicators (endophenotypes) for psychosis, schizophrenia and autism in children and adolescents, in order to try and prevent these individuals from developing these disorders later in life. As such, BO has initiated several projects, including pharmacological challenge studies in healthy volunteers, treatment studies in patients with schizophrenia, studies in children and  adolescents with developmental disorders, translational studies in animals, and a project using concurrent EEG and fMRI methodology. In addition, BO collaborates in many national and international projects. Currently, his research has been sponsored by a large number of major and minor research grants, both in Denmark and in Holland. He has been promotor, co-promotor and project-leader of a large number of preclinical and clinical projects in both Holland and Denmark.
