Promotor: Prof. D.I. Boomsma
Co-promotors: Prof J.J. Hudziak, Dr. C.V. Dolan
Bachelor and Master in Psychology at the University of Amsterdam, the Netherlands, with specializations in Statistical methods (cum laude) and neuroscience (cum laude)
January 2011 - present
Professor of Genetics in Psychiatry (0.88 fte, fixed term), Academic Medical Center, Amsterdam
November 2007 - December 2011
Senior Researcher (0.88 fte, tenure position), Department of Psychiatry, Utrecht Medical Center, Utrecht.
The main research projects in which I am involved are:
- “Improvement of phenotyping in Genome Wide Association studies on schizophrenia: an application of Latent Class Factor Analysis”. (funded by NWO; 250,000 Euro)
I am the prinicipal investigator of this project. The main goal of the current proposal is to improve the assessment of individual differences in schizophrenia, and to incorporate these improved phenotypic assessments in subsequent Genome Wide Association analyses.
- “Genetic Risk and Outcome in Psychosis (GROUP)”
This is a longitudinal study on gene-environment vulnerability and resilience in both clinical and non-clinical populations which offers the opportunity to elucidate etiological and pathogenetic factors influencing the onset and course of psychotic disorders.
- “The European First Episode Schizophrenia Trial (EUFEST)”
I am the statistical advisor of this project. The aim of the European First Episode Schizophrenia Trial (EUFEST) is to compare treatment with amisulpride, quetiapine, olanzapine and ziprasidone to a low dose of haloperidol in an unselected sample of first episode schizophrenia patients with minimal prior exposure to antipsychotics.
- “Optimization of Treatment and Management of Schizophrenia in Europe (OPTiMiSE; funded by FP7; 11,800,000 Euro). I am the senior statistical consultant of this project. The main aim of this study is to optimise current treatments in schizophrenia and explore novel therapeutic options for schizophrenia.
October 2010 - April 2011
Visiting scientist, Department of Genetic Epidemiology, Queensland Institute of Medical Research, Brisbane, Australia.
The aim of this visit was to collaborate with Prof. Dr. Peter Visscher and Dr. Naomi Wray on a study on the role of Copy Number Variants (CNVs) in mental retardation and schizophrenia. I discovered a novel region which is significantly enriched for large (>1Mb) CNVs in patients with mental retardation and schizophrenia compared to patients with mental retardation only. This work is not yet submitted for publication as the CNVs are currently verified based on PCR analysis but I expect that it will be submitted next month.
January 2007 - October 2007
Postdoc (0.8 fte, fixed term), Department of Biological Psychology, Vrije Universiteit, Amsterdam. This postdoc project was a continuation of the research project which started in September 2006.
October 2006-December 2006
Postdoc (1 fte, fixed term), Department of statistical genetics, Wellcome Trust Center of Human Genetics, Oxford, United Kingdom. In collaboration with Prof. dr. L.R. Cardon and Dr. D.M. Evans, two experts in statistical genetics, I worked on a statistical innovation in Genome Wide Association studies, and developed a method to increase statistical power to detect a functional genetic variant by prediction of unobserved SNPs based on information from the HapMap sample
September 2006-October 2006
Postdoc (0.8 fte, fixed term), Department of Biological Psychology, Vrije Universiteit, Amsterdam.
As part of this position, I collaborated with Prof. dr. M.C. Neale, and studied the psychometric
properties of a questionnaire that is used to assess smoking addiction: the Fagerström test for
nicotine dependence. This collaboration was continued in January, 2007.
September 2001-September 2006
AIO (0.8 fte, fixed term), Department of Biological Psychology, Vrije Universiteit, Amsterdam. The topic of the project was the exploration of genetic and environmental influences on Attention Problems and related childhood behavior problems, such as aggression and anxiety/depression.

Genetics in Psychiatry
Overall aim of research
Individual differences exist in the risk to develop psychiatric disorders. I aim to understand which factors contribute to these individual differences; why is it that some people are psychiatrically much more vulnerable than others? We have moved beyond the nature-nurture debate, as it is now clear that both genetic and environmental factors contribute. However, we have not yet revealed the specific etiological pathways which lead to psychiatric disorders. The identification of genetic and environmental risk factors requires thorough investigation of clinical symptoms, neurobiological functioning, structural and functional brain assessments, and molecular biology. I aim to integrate research findings obtained at these different levels of complexity. My position at a department of psychiatry allows me to collaborate with psychiatrists and neuroscientists and to conduct interdisciplinary research that is needed to increase the understanding of highly complex, multifactorial disorders.
Research at UMCU (2007-2011)
At UMCU, my research was primarily supported by a VENI grant. The overall aim of this project was to investigate how phenotypic heterogeneity can be accounted for in gene finding studies. This has resulted in important findings; showing that disorganization symptoms in schizophrenia patients are most strongly associated with genetic variants and with progressive changes in brain volume provided important directions for future studies (Derks et al. 2012d; Derks et al. 2012a). Second, I have developed new statistical methods for detecting genetic variants. For example, genetic analyses which focus on chromosomal segments were shown to have increased statistical power compared to analyses which focus on the role of individual Single Nucleotide Polymorphisms (Derks et al. 2012e). In total, the Veni project has resulted in 19 publications (8 first author, 2 last author, 9 co-author).
Research at AMC (2012-present)
In January 2012, I moved to the Academic Medical Center Amsterdam where I became professor of Genetics in Psychiatry. The main aim of my research group is to investigate the role of genetic factors in psychiatric conditions, including addiction, anxiety disorders, compulsive disorders, and schizophrenia. The focus of my research is on the development of new statistical methods aimed at discovering associations between genetic variants and psychiatric conditions. The ultimate goal is to study the biological processes which result in a psychiatric condition, starting with the genetic mutation with psychiatric diagnosis as the endpoint.
