When you have decided to participate in a Summer School of Leiden University, there are some matters you need to know before arrival. Please take a few minutes to read through the information here to find out what you can do from your side to smooth the process.

Food security is challenged by a growing global population and by climate change. Drought and soil salinity are considered the most important ones that inhibit crop yield and distribution. Worryingly, climate change is predicted to increase not only their frequency and severity, but also their co-occurrence,…

In photoactivated chemotherapy (PACT), a biologically active compound is caged by a light-cleavable protecting group.

Elke week organiseert ISGA de Research Seminar Series waarin onderzoek van zowel medewerkers van ISGA als van externen aan bod komt.

This thesis is largely an experimental study on the formation of solid-state simple and complex organic molecules in the H2O-rich and CO-rich ice phases of dense interstellar clouds and dark cores.

In this thesis we have discussed several parameters that affect the electrochemical conversion of enviromentaly harmful molecules such as nitrates and carbon dioxide to more valuable and less deleterious compounds, in order to cast light onto the mechanism of the reaction to achieve an efficient and…

This thesis mainly focuses on multimodal understanding and Visual Question Answering (VQA) via deep learning methods. For technical contributions, this thesis first focuses on improving multimodal fusion schemes via multi-stage vision-language interactions.

Timo Slootweg, associate professor at he department Philosophy of Law, published a chapter about Paul Scholten in

BlaC is the β-lactamase of Mycobacterium tuberculosis. We show that it can recover from inhibition by clavulanic acid and that phosphate helps it do so.

This thesis is based on five papers on several topics.

The inverse electron demand Diels-Alder (IEDDA) pyridazine elimination emerged in 2013 as a new bioorthogonal reaction and constitutes a prime example of what is now known as dissociative bioorthogonal chemistry. The research described in this Thesis aims to develop synthetic strategies which enable…

De tweede geheel vernieuwde editie van 'The E-Primer' bespreekt hoe een breed scala experimenten kan worden geprogrammeerd in E-Prime 3. E-Prime is een van de meest gebruikte softwarepakketten voor het ontwerpen van psychologische experimenten.

Leiden University offers a unique range of summer courses where you can broaden or deepen your knowledge or share your expertise with fellow students. The choice of academic courses is very diverse, ranging from Law, Big Data, Languages and Linguistics to Maths and Natural Sciences, Biology, Biomedical…

Freshwater biodiversity has been threatened by eutrophication due to excessive nutrients in the environment. Releasing the freshwater species from such pressures requires efforts from industry and manufacturers to avoid emissions to vulnerable and high-risk regions.

This dissertation aims to advance understanding of amoeboid single cell migration under the influence of changing physicochemical environmental properties. The particular focus is on the relatively unknown influence of differing physical properties in the extracellular environment, such as the migratory…

This doctoral thesis is an effort to understand how lipid phase-separation induced by diacylglycerol analogues in lipid-based nanoparticles affects their in vivo behavior, leading to specific nanoparticle-protein communications and selective cell targeting.

The application of nanomaterials in industrial processes and consumer products provides many societal benefits, but can also lead to the release of nanomaterials into the environment. The work in this dissertation aims to provide insights into the potential environmental impacts that may follow from…

De Leiden Slavery Studies Association (LSSA) is toegewijd aan het bevorderen van een beter begrip van slavernij en post-slavernij in elke periode en elk geografisch gebied.

The thesis is about the study of shell evolution of the Hydrocenidae of the genus Georissa. This thesis started with a general overview on the evolutionary process of animals due to ecological changes.

Galaxies in the Universe are distributed along the intricate framework of the Cosmic Web. Groups and clusters of galaxies comprise the densest regions in this network, and therefore, are excellent cosmic laboratories to study different aspects of galaxy evolution in extreme environments.

Learning a programming language is challenging. Even one of the first –but crucial– concepts to learn, variables, is hard to grasp. Variables can represent different roles and functions within a code and need to be named appropriately to support code comprehension and debugging.

Bestudeer complexe veiligheidsvraagstukken, zoals terrorisme en cyberdreigingen, met een focus op real-life cases in Security Studies aan de Universiteit Leiden. Ontwikkel academische en professionele vaardigheden en bereid je voor op een master of carrière.

What is the effect of light at night on plant phenology and physiology, and how does this affect plant interactions with other species?

Op 10 november 2021 verdedigde Carmel van Niekerk-Jacobs het proefschrift 'Realising the right to reproduce with assistance in South Africa'. Het promotieonderzoek is begeleid door prof.dr. J.J. Sloth-Nielsen en prof.dr. T. Liefaard.

Hybrid zones occur where two species meet and produce offspring (hybrids). Typically, hybrids show a considerable reduction in fitness. In this thesis two hybrid zones are treated.

eLaw onderzoekt de rol van het recht in de informatiemaatschappij: hoe kan het recht bijdragen aan een goede werking van informatie- en communicatietechnologie, en het gebruik ervan door burgers, bedrijven en overheden?

This thesis explores the theoretical and observational properties of distant massive galaxies that harbour active black holes in their centres and shine brightly at radio wavelengths.
