The overarching goal of this thesis is to set the foundations, but also make the first essential steps towards establishing a comprehensive, mesoscopic, hydrodynamic theory of epithelial tissues. The stage is set by an exhaustive study of topological defects in passive p-atic liquid crystals, singularities…

The human body consists of hundreds, perhaps thousands of different types of cells, each with different morphologies and functions, despite having the same genome.

In this work, we investigate the minute circular dichroism effects of single nanoparticles.To this aim, we apply photothermal imaging with a polarization-modulated heating beam.

For each living organism health is ensured by correct functioning of its cells. Cells therefore have elaborate methods for regulation of their proteins.

Electron microscopy has become an extremely important techniquein a wide variety of elds.

The elementary excitations of magnets are called spin waves, and their corresponding quasi-particles are known as magnons. The rapidly growing field of Magnonics aims at using them as information carriers in a new generation of electronic devices, (almost) free of electric currents.

In this thesis unconventional tools based on fluidic interfaces were developed to study the surface and interfacial chemistry of graphene, to characterize the intrinsic properties of graphene, to disentangle the effects of substrate and of the environmental factors, and to improve handling protocols…

Quantum position verification (QPV) - the subject of this thesis - is a novel way to authenticate unknown nodes in a quantum network without the need to physically meet up.

Pancreatic ductal adenocarcinoma (PDAC) is among the cancers with the highest mortality rate, despite a relatively low incidence.

The ultimate goal of cosmologists is to find a cosmological model able to explain the current observational data.

Keeping our planet healthy in a just and responsible way.

This thesis explores how electron paramagnetic resonance (EPR) spectroscopy can be used to investigate key biochemical processes.

n this PhD thesis, the recombination of different atomic lattices in stacked 2D materials such as twisted bilayer graphene is studied. Using the different possibilities of Low-Energy Electron Microscopy (LEEM), the domain forming between the two atomic layers with small differences is studied.

All the data stored and processed by our computers is encoded as sequences of zeros and ones, called bits. Quantum computers offer an alternative to this traditional way of encoding and manipulating information.

Young Dutch people’s reading skills have been declining for years. The main reason for this is that many have difficulty with reading at greater depth. Teach pupils to read actively in order to construct meaning is what Leiden researchers Paul van den Broek, Christine Espin and Anne Helder write in…

Overview of all dissertations published by PhD candidates from CML.

Researchers from more than 30 countries have been discussing the changes in reading through digitization in the European research network E-READ. Adriaan van der Weel, Senior University Lecturer, spoke about the network’s achievements in the German newspaper Frankfurter Allgemeine Zeitung.

Young people are more likely to find long texts unappealing to read, particularly with all the digital distractions. To improve young people’s reading skills, Elise Swart and Hannah De Mulder are starting an innovative study to make reading fun again.

Dutch influencers like Romy Boomsma and Nina Pierson have a huge following on Instagram and are increasingly sharing book tips there. Researcher Aafje de Roest wants to find out more about the reading culture they are promoting and its effect on the reading habits of their mostly young female follow…

How should the Quran be read? The manuscript of this holy book makes different interpretations possible. Researcher Marijn van Putten has been awarded an ERC Consolidator Grant of two million euros to explore centuries-old recitations.

Speculation about alien life, a new nitrogen map, AI as a thesis supervisor, groundbreaking telescopes and multi-million-euro investments to combat antimicrobial resistance – the diversity of these topics shows that our readers are just as broadly interested as our researchers.

Matheus Mendes was awarded the 12th Jaap Doek Thesis Prize at a ceremony on 13 December 2024 for his thesis on the right to read. The prize honours outstanding master’s theses in children’s rights.

Research into depression in children, Leiden alumni in the Dutch House of Representatives and an exceptional achievement by one of our students: what do this topics have in common? They are among our most read stories of 2021.

On August 29th Rob Tijdeman held his valedictory lecture in a full house Academy Building as a professor in Number Theory, entitled 'My life as a mathematician'. After his lecture he was appointed, in name of the Queen, Knight in the Order of the Dutch Lion by the maior of Leiderdorp.
