Saeedeh Shahnahpur defended her thesis on 13 September 2016.

Some conflicts involve many Muslims as foreign fighters; other conflicts attract only relatively few combatants from abroad. Isabele Duvesteyn and Bram Peeters

This article written by Marieke Liem & Alexander Kamprad investigates the relationship between terrorism and interpersonal violence. They conducted cross-national analyses on the effects of terrorism mortality rates on homicide rates. Results showed that terrorism appears to be robustly and positively…

PhD defence

Can we identify different degrees of economic integration, both within and between regions, on the basis of archaeological proxies?

In this thesis, Quantum computing, norms, and polynomials, we investigate the interplay between quantum mechanics, complexity theory, and functional analysis, three central areas of physics, computer science, and mathematics, respectively.

We explored the Universe using weak gravitational lensing, a phenomenon that occurs when light from distant galaxies is bent by the gravitational fields of closer cosmic objects, much like how a lens distorts light.

From 1 August, Hermen Jan Hupkes has been appointed Professor of Non-Linear Analysis at the Mathematical Institute. 'Initially I don't think that much will change,' Hupkes says. 'My research and supervising future researchers will continue as before.'

What are the environmental impacts of widespread integration of bio-based products into the construction industry?

What mismatch of socioeconomic and environmental values is preventing Circular Collaboration in Dutch housing renovations?

A framework for prospective/ex-ante life cycle assessment (LCA) and ecological risk assessment (ERA) of emerging technologies is developed and applied to a case study of III-V/silicon photovoltaic panels.

Our group is part of the Metabolomics and Analytics Centre where we accompany the data from its acquisition all the way to the publication of identified associations and biomarkers for a range of human diseases. The generated data of the metabolic measurements are assessed using an in-house quality…

Through the Academy of Creative and Performing Arts, multiple gifted bachelor and master students of Leiden University and the University of the Arts The Hague can fully develop both their artistic and academic talents by choosing academic or artistic minors or electives.

Isotopic and zooarchaeological investigations in the Dominican Republic and Jamaica

This article describes that although the use of the concept of energy justice is new, normative interpretations have long been part of energy policy.

Why use Google Maps when you can also calculate your bike route based on your own data. Statistician and cyclist Alexander Dürre sees statistics in everything around him. He analyses data of soccer games and calculates the possible winners of cycling races. ‘When I have too much time, I apply statistics…

The LOFAR radio telescope produces petabytes of data every year. Radio Astronomers use complex multi-step pipelines to process this data and produce scientific images.

The increasing competition in the automotive industry requires the tailored, swift development of technologically sophisticated vehicles. Therefore, the computationally expensive state-of-the-art simulation technologies are combined with optimization algorithms. An example of a real-world optimization…

The transition to electric vehicles (EVs) reduces vehicle emissions to combat climate change. EVs raise concerns regarding the production of lithium-ion batteries and related emissions; while batteries can also provide energy storage services for the electricity system.

This thesis involves three topics: benchmarking discrete optimization algorithms, empirical analyses of evolutionary computation, and automatic algorithm configuration.

Exploring Late Bronze Age attitudes towards martiality through experimentation and micro-wear analysis

The use-wear analysis of domestic implements provided new insights of the Single Grave Culture population in the Netherlands.

‘There’s a lot of evaluation in the Netherlands, but this doesn’t always lead to change,’ says Wout Broekema, Assistant Professor of Crisis Governance at the Institute of Security and Global Affairs. Learning from a crisis is complicated, but experts can help.

Are predictive archaeological maps a reliable tool to play an important role in the spatial planning? One of the goals of this project was to develop best practices for the production and application of the models.

A new study published in Archaeometry describes the unexpected results obtained from analyses of five human teeth discovered in a ritual cache at an enslaved African plantation site on the island of Saba in the Caribbean.

The lack of success of new CNS drugs in clinical development is in part due to the complexity of the CNS, unexpected side effects, difficulties for drugs to penetrate the brain, but also by the lack of biomarkers.

It sounds credible: ‘Research has shown that…’, but is it really? Read in the research dossier ‘From data to insight: the importance of sound research methods’ how Leiden University contributes to more reliable social science research.

New funding allows IBL-researcher Herman Spaink to purchase a measurement device for more studies on human diseases such as cancer and tuberculosis using zebrafish as the model system.

What are the possibilities of converting biowaste streams into value added products? What current and future technologies will enable this transition with minimal environmental and economic costs? The researchers in H2 steel project will enable the transition of sewage sludge into green hydrogen, steel…
