We study the interplay of topology and geometry with chirality for several passive and active systems, employing both analytical and numerical methods.

Developing new methods for performing improvised music

Viral hemorrhagic fever (VHF) is a group of acute diseases caused by highly infectious viruses including Ebola, Lassa, Dengue viruses. Its high mortality rate poses high risk to public health, however, studies on VHF have been hampered due to the non-availability of proper models and incomplete knowledge…

Mechanobiology is a major area in biology, however, mechanics is currently a missing element in drug development pipelines. This has led to a high cost for the society. Mechanotoxicity of drugs often appears as a long-term side effect of drugs, and has led to removal of drugs from the market. Furthermore,…

Does Artifical Light at Night (ALAN) disrupt seasonal physiological and behavioral patterns in migrating freshwater fish?

What are the precise identities, possibilities and current practice examples of the various time frames in music and what bearings do they have individually and in combinations on the speed of the music?

The goal of this study is to systematically investigate how intonation (speech melody) is conveyed in whispered speech.

The effects of anthropogenic noise on interactions between predators and their prey are still little understood.

Lecture, This Time for Africa!

This study investigates the perception and production of emotional prosody by native and non-native listeners and speakers, i.e. Chinese and Dutch listeners and speakers, including Dutch L2 learners of Chinese.

This project examines how speakers store and process regular pitch variation.

How do we process language and speech? How do we integrate information at different levels – intonation, sentence structure, meaning, tone, words, sounds - and how does information at one level interact with information at another level?

This dissertation provides a formal description of the relationship between diatopic/diachronic micro-variation and phonologization through analysis of the phonetic/phonological properties of unstressed vowel reduction and vowel insertion in two Northern Italian dialects.

Industrial ecologists Stefano Cucurachi and Flora Siebler are part of the new consortium PROGENY, which received 3.6 million euros from the European Commission. PROGENY is an exciting project that will study the possibilities of soap films for innovations, such as ultra-thin screens.

All languages use melody in speech, primarily via rises and falls of the pitch of voice. Such pitch variation is pervasive, offering a wide spectrum of nuance to sentences – an additional layer of meaning. For example, saying “yes” with a rising pitch implies a question (rather than an affirmation).…

We focus on a better understanding of the mechanisms of cancer drug resistance and metastasis.

In this thesis, a system pharmacology approach, integrating metabolomics, pharmacology and chemical biology, was applied to understand and modulate the endocannabinoid system across different model systems (cells, zebrafish, mice and humans).

The Co-Align Conference 2023 will be held on 16 May 2023 at Leiden University.

The type-IV secretion system (T4SS) is a machinery able to transfer DNA and proteins between bacteria and in certain cases also to eukaryotic cells.

The experiments described in this thesis employ local lentiviral knockdowns in brain areas of female zebra finches followed by behavioural assays consisting of preference and Go/Nogo tasks.

To increase clinical success rate of drugs, a better understanding of drug action mechanism and disease dynamics is required. Metabolomics, which studies small molecules involved in biochemical processes in organisms, has shown to be a useful tool for this better understanding.

This thesis is a (biased) journey through very different topics in astrophysics: quasars and new populations of active galactic nuclei, gravitational waves from merging black holes, and protoplanetary discs around young stars.

Stimulating the vagus nerve, which provides a direct link between the gut and brain, makes people pay less attention to sad facial expressions. This research study by psychologists Katerina Johnson and Laura Steenbergen is published in the journal Neuroscience, and made it to the cover.

In this thesis, we describe the latest advances in SQUID-detected Magnetic Resonance Force Microscopy (MRFM).

This thesis describes the development and optimization of the first molecular tools to study the enzyme PLA2G4E.

Animal Sciences’ contributions to the Host-Microbe Interactions research theme focus on the interaction of animal hosts with pathogenic microbes but also the beneficial role of the gut microbiome.

The main aim of this thesis was to unravel the signaling and regulatory networks that drive tumor cell migration during breast cancer metastasis.

In this article, Thijs van Dooremalen and Philip Smith investigate how public discourse of heatwaves have shifted in British newspaper discourse, drawing on Raymond Williams’s theory of dominant, emergent, and residual cultural patterns to analyse changes in language and interpretation over recent d…

Prostate cancer (PCa) is one of the most prevalent cancer in males.

For centuries astronomers studied the Universe by collecting light. Nowadays, we are living in times of great technological advancements, which allow us to explore our Universe in a new way - though gravitational wave radiation.
