With this thesis the PhD-candidate aims to enrich the body of evidence concerning the relation between stress and health, and the mediating role of (un)conscious perseverative cognitions, which is captured in the extended perseverative cognition hypothesis.

The research question is that unconscious perseverative cognition (UPC) is responsible for a considerable part of cardiovascular (CV) activity that occurs even in the absence of threats and other stressors that one may encounter in one’s daily life.

Can epigenetic changes explain associations between early life stress and health outcomes?

The overall objectives of my thesis are to investigate the dynamics of the sorghum root microbiome and to explore the beneficial effects of the root microbiome on sorghum growth and stress tolerance.

Cellular stress response pathways are activated upon exposure to chemicals and help organisms deal with various molecular dangers (e.g. oxidative stress). When these pathways become hyper-activated an adverse response takes place and cells die, which may lead to organism-level toxicity such as drug-induced…

I want to understand the overlap between physical health, mental health, and healthy aging and whether/how stress (behaviorally and biologically) may tie these concepts together.
