Brief Curriculum Vitae

 

Trained in psychology with a specialization in psychonomics and neuro/biopsychology and received a PhD in psychology from the faculty of social sciences at Utrecht University. After a short employment as researcher/programmer at Intomart GfK in Hilversum, the Netherlands, started a post-doc fellowship in the Department of Sleep and Cognition at the Netherlands Institute for Neuroscience of the Royal Academy of Arts and Sciences. Currently continuing this work employed at the Vrije Universiteit Amsterdam.

Research interests include using different statistical techniques to get a more complete and full understanding of clusters in heterogeneous patient populations as well as individual patterns of symptoms. Furthermore, a strong affinity with programming (proficient in multiple languages) software and website design. Lastly, interests also include academic education and, more generally, communication of research results to the public.

Present work mainly focuses on insomnia, a very common disorder known to have a large socio-economic impact. A major part of activities are maintaining surveys and computerized tasks in a web-based assessment system, the Netherlands Sleep Registry (NSR, www.sleepregistry.eu) through which a large group of good and poor sleepers (currently around 13000 people participate) are assessed. Responsible for analysis of the data acquired in this NSR. This thus creates a large database of sleep phenotypes. Classifying these insomnia phenotypes is a first step towards further research on finding biomarkers for this condition.

Specialties: Psychometric assessment, eye tracking and neuroimaging techniques with a strong (web) programming and design capability (HTML, PHP, MySQL, Javascript, CSS, Photoshop, Illustrator, Matlab, Python).
