During adolescence, mood disorder onset peaks. Mood variability is associated with negative mental health outcomes, so understanding biological factors that might be associated with mood variability, such as sleep and structural brain development, could elucidate the mechanisms underlying mood and anxiety…

Phospholipase A/acyltransferase 3 (PLAAT3) and PLAAT4 are enzymes involved in the synthesis of bioactive lipids. Despite sequential and structural similarities, the two enzymes differ in activity and specificity.

This project aims to investigate the underlying (neurocognitive) linguistic processes of ellipsis resolution, particularly gapping.

Hydrogen can help to solve the climate problem. At least, if we start producing it in the right, clean way. Leiden researchers mapped out the global environmental impact of hydrogen production and looked ahead to 2050. They published their work in Energy & Environmental Science.

Can we tailor catalysts at the atomic scale by means of high-school chemistry and geometry rules?

Lecture, European Union Seminar

Ludo Block wrote the eleventh chapter of the book 'Post-Crimea Shift in EU-Russia Relations: From Fostering Interdependence to Managing Vulnerabilities'. His chapter 'Business as Usual? Police Cooperation under a Cloud of Political Animosity' can be found on page 204 of the book.

On 19 September 2019, Lynette Janssen defended her thesis 'EU Bank Resolution Framework: A comparative study on the relation with national private law'. The doctoral research was supervised by Prof.mr. W.A.K. Rank and prof. M. Haentjens.

The progressive loss and degeneration of dopaminergic neurons is a major pathological hallmark of Parkinson's disease (PD). The onset and progression of PD can be triggered by multiple risk factors, for instance, genetic mutation, environmental exposure, and aging.

The local ordering of atoms at the surface of a metallic particle determines its catalytic activity and selectivity. As energy systems of the future will be based on efficient catalytic conversion of small molecules in closed cycles, we study how structural effects of catalysts can be used to our ad…

Electrolysis is a technique that can be used to convert CO2 into fuels and other useful products. To do this efficiently and on a large scale, however, we need to understand exactly how electrolysis works. Professor Marc Koper is an expert in this field.

Imagine we could convert the greenhouse gas CO2 into synthetic fuels using sustainable energy. This would enable us to reduce the amount of CO2 and at the same time store wind and solar energy in an innovative way. Chemist Akansha Goyal (Leiden University) is conducting fundamental research to make…

Leiden University is committed to reducing our water consumption.

Article by Leiden University political scientist Daniel Thomas about shifting norms for membership in international organisations.

Ms. Anaïs Massot defended her thesis on 26 January 2021

In the Catalysis and Surface Chemistry group, we investigate how catalysis works on the molecular level. The group is divided in six subgroups, focusing on different aspects of heterogeneous catalysis, homogeneous catalysis and electrocatalysis.

Managing scarcity to serve the public interest is a classic government task. An important way to execute this task is by allocating individual rights that are only available in limited quantities, such as CO2 emission allowances, gambling licences, subsidies, radio frequencies, public contracts and…

The chemical industry must continue to innovate for a more sustainable, healthier society. The reseachers from the Leiden Institute of Chemistry (LIC) contribute by applying their knowledge to themes such as sustainability, energy and health.

The aim of the project is to unravel the genetic and contact relations between the indigenous languages of Mesoamerica (Mexico and western Central America) and the Middle Andes region (Ecuador, Peru, Bolivia), as part of a larger endeavor to understand the historical process of the peopling of the Americas…

Between the 16 and 18 October, 85 Advanced MSc International Relationsand Diplomacy first-year students accompanied by team members embarked on an academic excursion to Brussels and various of its prominent EU institutions.

On 26 June 2019, Lisa Louwerse defended her thesis 'The EU’s Conceptualisation of the Rule of Law in its External Relations: Case Studies on Development Cooperation and Enlargement'. The doctoral research was supervised by Prof. C.A.P. Hillion.

The drafting of a handbook that serves as the first guide to European law in the area of children's rights, taking into account the case law of the European Court of Human Rights and the Court of Justice of the European Union (CJEU), as well as the decisions of the European Committee of Social Rights…

Consequences for sediment stability and seston trapping

I want to understand the overlap between physical health, mental health, and healthy aging and whether/how stress (behaviorally and biologically) may tie these concepts together.

This dissertation is a comprehensive description of the Jiăomùzú dialects. These dialects belong to the Tibetan-Birmese language of the rGyalrong spoken in the province Sìchuā, China.

This project aims at investigating the multidirectional effects of forced and voluntary forms of migration in the ancient Near East.
