In this thesis we explore machine and deep learning approaches that address keychallenges in high dimensional problem areas and also in improving accuracy in wellknown problems. In high dimensional contexts, we have focused on computational fluid dynamics (CFD) simulations.

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

Leiden University was founded in 1575, thanks to William of Orange. According to tradition, he founded the University to reward the citizens of Leiden for their resistance to the Spanish occupiers.

Are you eager to bring your own questions and curiosity into scientific research? Do you question intelligence and technology in a fundamental, creative, and playful way? Could you be a researcher who challenges scientific practice and pushes its boundaries?

Is there a sufficiently large market for drug screening and testing in Zebrafish larvae using membrane fusion?

Catalysis is of extreme relevance in the production of everyday materials and plays a central role in many aspects of our life.

It is generally accepted that a university education is about more than knowledge transfer alone. Alongside knowledge and understanding, students should develop the skills required to apply this knowledge and understanding.

In higher education intermediate assessment is used in different ways. In her PhD research Indira Day shows that lecturers should be able to continue to have the freedom to use various test forms, because not one type of test is optimal.

During my PhD research, I studied the photon statistics of light emitted by a microcavity that contains a single quantum dot (QD) on resonance.

With the help of quantum mechanics, digital quantum hardware may be able to tackle some of the problems that are too difficult for ordinary computers. But despite these expectations and the ongoing effort of the research community, reliable quantum computers are not yet realized in a lab setting.

It is essential for researchers to be able to obtain independent research funding to advance in their careers.

AI Labs are collaborations of Leiden University with external parties such as industry, governmental parties and other universities on the topic of Artificial Intelligence. The Science institutes of Leiden University are unique located in the largest Bioscience Park of the Netherlands, next door to…

The Philosophy of Law Department is responsible for various courses both in the Bachelors and the Masters.

Terrorism only poses a small risk to people but tends to be a major source of public fear. Through fear, terrorism has far-reaching implications for public governance.

This thesis describes the design, characterization and application of dextran based crosslinked network.

Most of the PhD graduates (about 70 percent) find a job outside of academia. The majority of them successfully embark on a career in education, administration, heritage, journalism, or business. Other PhD graduates find employment in an academic or semi-academic environment. A considerable number of…

This dissertation is concerned with the development of grammar. Starting from a usage-based perspective, which holds that children use domain-general learning mechanisms to acquire the grammatical patterns of their mother tongue, Beekhuizen shows how to operationalize various concepts from this tradition…

The electrochemical oxygen reduction reaction (ORR) is an essential half-reaction for the utilization of hydrogen as a sustainable fuel, via the conversion of hydrogen to electrons and protons facilitated by the ORR. In the most common fuel cells, the ORR is requires high loadings of non-abundant platinum…

Assessing the risks of engineered nanomaterials (ENMs) solely on the basis of experimental assays is time-consuming, resource intensive, and constrained by ethical considerations (such as the principles of the 3Rs of animal testing). The adoption of computational toxicology in this field is a high p…

In the last two decades, there have been heated public and scholarly debates in France, the United Kingdom, and the Netherlands on the violent end of empire. Nevertheless, the broader comparative investigations into colonial counterinsurgency tend to leave atrocities such as torture, execution, and…

Galaxies are environments where gas coalesces, cools, and is converted into stars. However, it remains unclear the exact mechanisms through which galaxies acquire, redistribute and lose their gas.

This thesis explored the question whether Scrum methodology might function as an appropriate scaffold to enhance students’ learning and to support teachers in context-based secondary chemistry education.

The work described in this dissertation contributes to a better mechanistic understanding of nanoparticles in vivo. To achieve that goal, we used the zebrafish as a highly predictive pre-screening model of nanoparticles.

In this thesis, we extend the concept of null models as canonical ensembles of multi-graphs with given constraints and present new metrics able to characterize real-world layered systems based on their correlation patterns.

How safe do you feel when you’re walking around the streets of Leiden? Do you generally feel safe? Are there any situations when you feel unsafe in the city? These are the kinds of questions that Leiden’s City Criminologist Marianne Franken – from Leiden University – hopes to be able to answer. In collaboration…

Schistosomiasis is an acute and chronic disease caused by blood dwelling parasitic trematodes of the genus Schistosoma, and it is classified as the second most socioeconomically devastating parasitic disease, second only to malaria.

Detection of cerebral beta-amyloid (Abeta) by targeted contrast agents remains of great interest to aid the in vivo diagnosis of Alzheimer's disease (AD). Bis-styrylbenzenes have been previously reported as potential Abeta imaging agents.
