In this thesis, the focus lies on studying glucocorticoid receptor dynamics in living cells with the aim of understanding how this transcription factor finds its DNA target sites to regulate transcription.

Research in the group Clinical Neurodevelopmental Studies is focused on understanding and influencing developmental mechanisms in children and adolescents, in particular the development of psychopathology, ranging from mild to severe neurodevelopmental disorders.

Does the political context (e.g., democracy vs. authoritarianism) influence what makes people perceive authorities as legitimate?

University-school partnerships are important constellations for teachers’ professional learning. The present study investigates how both teacher characteristics and contextual factors are related to teachers’ motivation to participate in the university-school partnership, and the relationship between…

What are the developmental pathways to social anxiety (disorder), the causal processes and maintaining factors? How do these factors interact in the development of social anxiety disorder? How can this knowledge be used to design and implement effective preventive intervention programs for youth?

The factors that dynamically sculpt the inter-regional correlation of brain patterns are poorly understood. Here, we test the hypothesis that they are shaped by the catecholaminergic neuromodulators norepinephrine and dopamine.

The currently available in vitro generated human skin equivalents resemble the human skin in many aspects. However, some essential barrier characteristics do not fully mimic the native barrier. Consequently, the human skin equivalents cannot be used for screening of drugs for skin penetration.

How do genetic and environmental factors make us vulnerable to depression?

Heart failure is a major health care problem with high mortality.

Consequences for sediment stability and seston trapping

In this thesis, we aimed to better understand the underlying mechanisms involved in TNBC progression and metastasis formation and discover new targets to reduce breast cancer related deaths.

How can data science improve tax administration? Mark Pijnenburg, a senior data scientist at the Netherlands Tax and Customs Administration, decided to investigate this in a dissertation. He talks about his experiences: 'Sometimes a technique is scientifically interesting, but not applicable in real…

Biosynthetic gene clusters (BGCs) for natural products are widespread in microbial genomes, and they are rapidly exchanged. This research assesses the factors that control the spread of BGCs and resistance genes in nature. This includes risk assessment for the spread of engineered DNA in nature.
