I am a dedicated and enthusiastic lecturer, and involved in the following programs and courses:
From 2012-2017 I organized the minor Brain & Mind, and since 2011 I coordinate in this minor the course Nature versus Nurture.
Since 2017, I am chair of the Faculty of Science Examination Board.
After working for 10 years in one of the largest twin registers in the world to study the heritability of ADHD and related disorders, I moved in 2010 to the Center for Neuroscience and Cognitive Research (CNCR). The CNCR works at the frontiers of statistical and biological genetics and allowed me to expand my horizon, and extend my knowledge on novel methodologies and biological pathways. My main interest is in the comorbidity between psychiatric traits, potential shared genetic overlap, and underlying biological pathways. I published several papers that focused on shared genetic mechanisms between specific disorder dimensions in neurodevelopmental disorders. Another line of research is genetic by environment interaction (GxE) for which I currently focus on environmental factors that interact with genetic burden for externalizing problems. In 2015 I published a huge meta-analysis on virtually all published twin studies of the past 50 years on human traits [Nature Genetics, 2015], which is nicknamed ‘the mother of all heritability studies’. I supervise four PhD students with whom I work on gene-set analyses for psychiatric traits, genetic overlap between ASD and comorbid traits, the genetic link between psychopathology and brain networks, and sensory sensitivity in autism.
