What’s really happening in the space between the cells in your body? With the Collagen Canvas project, students from Leiden University invite you to explore this question by blending science with art. This interactive artwork immerses you in the dynamics of the extracellular matrix—the invisible structure…

We will study how inoculation of former arable land with soil (including the microbiome, soil fauna and seeds/rhizomes of ground flora) from old forests along with planting targeted tree species mixtures will improve productivity and more rapidly restore forest-adapted communities and ulttimately result…

One of the most crucial aspects of our behaviour is our motivation to explore novel environments and interact with new people. This became painfully clear during the COVID-19 lockdowns, when many people suffered from lack of new experiences and real-life social interactions. The relevance of novelty…

This dissertation contains four works during my PhD. Different biomaterials have been designed based on coiled-coil peptides. These biomaterials have a range of applications, inclusing drug delivery, cell sorting to cell-cell fusion.

Negative perceptions of ambiguous social cues, social performance and physical arousal in socially anxious youth

We consider the propagation of electrical signals through nerve fibres.

Cryogenic electron microscopy (cryo-EM) is a powerful technique used to visualize the inside of cells and to study specific protein complexes. Within this thesis, I describe the use of various cryo-EM techniques to gain insight into the structural changes of the human pathogen, Vibrio cholerae, as it…

How is inflammation in tuberculosis controlled by interplay between autophagy and inflammasome signalling?

Humans share meaning through language. Over time, repeated interactions have shaped languages into forms that match our cognitive preferences, making them structured, expressive, easy to learn, and ultimately, meaningful.
