The ability to count is a property not often attributed to materials, despite the abundance of memory in materials. Regardless of how a material stores information, it is often difficult to retrieve exactly ‘what’ a material remembers.

All crested and marbled newts (the genus Triturus) suffer from an unusual genetic abnormality, called a balanced lethal system, that kills exactly half of their offspring. How can a trait so disadvantageous have survived millions of years of natural selection?

Multiple stars, that is two or more stars composing a gravitationally bound system, are common in the universe.

This thesis deals with properties of Jacobians of genus two curves that cover elliptic curves.

This thesis discusses the physical and chemical processes than influence the composition of forming planets.

Biological cells, the basic building blocks of all life forms, are surrounded by a lipid membrane. More than half of the membrane is occupied by membrane proteins, which can regulate the cell functionality through specific arrangements.

Binnen het brede netwerk van de Universiteit Leiden neemt het instituut deel aan onderzoek binnen de volgende profileringsgebieden:

Commerciële bedrijven die gebruik willen maken van de expertise en faciliteiten worden doorverwezen naar LAB , de commerciële eenheid die verantwoordelijk is voor gespecialiseerd laboratoriumwerk.

In vroegmiddeleeuws Engeland was er belangstelling voor de geschiedenis van het Romeinse Rijk en koningen namen imperiale titels als 'imperator' en 'basileus' over. Hoe kunnen we deze interesse verklaren en welke functies hadden imperiale ideeën en de ontvangst van de klassieke wereld in vroegmiddeleeuws…

The main aim of this project is to reveal and unravel the invisible histories of the UN, transcending the dominant Western perspective to recover the historical agency of Global South actors. The research will investigate how the UN has both facilitated and limited their role in shaping global order…

The intradermal administration route is attractive for vaccine delivery, because of the highly populated antigen-presenting cells in the skin. However, the skin’s main physical barrier, the stratum corneum, prevents vaccines from entering the skin.

Beneficial plant-associated microbiota, particularly those inhabiting the rhizosphere, contribute substantially to plant health through pathogen suppression, stimulation of plant defence responses, and enhanced nutrient acquisition.

In this thesis we use state-of-the-art observations and simulations to provide the best constraints to date on the HVS ejection rate and constraints on the stellar content and dynamics at the GC, including the progenitor binary populations and their star formation history.

My PhD project studies how the temporally sequential Hox gene expression is regulated during head-tail patterning of the frog embryo.

In this thesis we study bistable reaction-diffusion equations on lattice domains.

Drug development is a time- and resource-consuming process that starts with the discovery and validation of a (protein) target that contributes to pathogenesis or disease progression.

To address the fundamental questions of how life on Earth emerged and how common life may be in the Universe, it is crucial to know the chemical composition of the planet-forming material.
