Towards a Biological Understanding of the Middle to Upper Palaeolithic Transition

A sustainable resource management is an essential aspect to satisfy the current human needs without compromising the needs of future generations.

A remarkable population of short period transiting rocky exoplanets with equilibrium temperatures on the order of 2,000 K has recently been discovered.

High-angular-resolution observations of the circumstellar material have uncovered numerous and very diverse substructures in protoplanetary discs, raising the question of whether they are caused by forming planets or other mechanisms.

The Copenhagen interpretation of quantum mechanics states that a measurement collapses a wavefunction onto an eigenstate of the corresponding measurement operator.

The cost-sharing standard (kostendelersnorm) – a regulation affecting recipients of supplementary income for older people, often with a migrant background – may lead to financial and health problems for thousands of people, economists Ernst-Jan de Bruijn and Heike Vethaak have found.

A cross-cut analysis of the ties between university research and fossil industries.

How much energy and greenhouse gas emissions can Dutch homes save? Xining Yang uses Leiden as an example and shows with his research how enormous the impact can be. At least, if we work harder on becoming more sustainable. Based on the models he developed, Yang will receive his doctorate on 28 June.

Systems with local constraints is a new finding in recent researches on complex systems. The heterogeneous spatial interactions and the temporal dependencies among those numerous units make it difficult to describe by traditional statistical physics.

On the 16th of September, Bert van Pinxteren successfully defended a doctoral thesis. The Leiden University Centre for Linguistics congratulates Bert on this achievement!

This research examines how punishment and deterrence is articulated and expressed in the management of migration in Mexico.

The section Developmental and Educational Psychology consists of more than 45 people, who are mainly involved in education and research.

Leiden University is working on a green, circular campus, with a significant reduction in energy consumption by 2050 as its goal, as elaborated in the Route Map Energy Transition Buildings, published in 2022.

A MSCA Global Fellowship that aims to explore the socioeconomic and environmental implications of a Latin America circularity transition, and its impact on the EU and global economy.

The meaning of the Swifterbant Culture for the process of neolithisation in the western part of the North European Plain (4900-3400 BC)

Exoplanets close in to their host star receive high levels of extreme ultraviolet (EUV) irradiation, capable of heating and ultimately driving the hydrodynamic escape of their atmospheres.

On the 6th of December, Buurtlab 070 and the Leiden University Green Office (LUGO) hosted an event at the Spinozahof in the Stationsbuurt, bringing students and local residents together to explore energy (in)justice through the serious game Sunjust.

Energy transition will entail the construction of large numbers of new energy installations. Such construction projects may meet with opposition from people living close by. Assistant Professor Bríd Walsh investigated how the local community can best take part in such projects.

Storing energy is one of the biggest challenges in the energy transition. Hydrogen could be a solution. Chemist Daan den Boer is researching how to make the chemical reaction needed to store energy in hydrogen as cheap and efficient as possible.

Lecture, Studium Generale

The Open Science Lab bundles expertise on Open Science at CWTS and contributes to and studies the transition towards Open Science at CWTS, Leiden University, and beyond. It serves as a knowledge broker, facilitator, and platform for learning and exchange.

Leiden University’s contribution to the Social Sciences Sector Plan is organized across several interconnected levels. The national Sector Plan themes define shared priorities across Dutch universities, while Leiden’s research themes and faculty focus areas provide direction and focus within the uni…

A new universitycommittee will assess potential new collaborations with the fossil fuel industry and determine whether they comply with the Paris Agreement.

Developing safer alternatives to harmful PFAS filters and seeking new enzymes for medical applications. Two projects with Leiden researchers have been awarded funding through the Dutch Research Council's (NWO) Open Technology programme.

The transition to new and renewable energy sources should be completed by 2050. Researchers in various disciplines at Leiden University are conducting unique research that will help us make this transition and reduce CO2 emissions.

This thesis addresses the challenge of sustainable urban development by analyzing the interplay between green and grey infrastructure to optimize resource use and ecosystem services.

The Indonesian Experience after the Fall of Suharto

Leiden University is an international, broad-based university. We distinguish five core domains for our research and teaching activities.

A full overview of THEOR PhD theses.

On 25 May, Roxane de Massol de Rebetz defended the thesis 'Beyond the dichotomy between migrant smuggling and human trafficking: a Belgian case study on the governance of migrants in transit'. The doctoral research was supervised by Maartje van der Woude, Joanne van der Leun and Masja van Meeteren.

Stakeholder engagement practices are on the rise in regulatory governance. This raises an important question regarding implications for regulatory legitimacy. Engagement mechanisms are not by default legitimizing: Even when initiated to tap into an array of ‘benevolent’ desiderata, unless carefully…

In our research and education, we focus on the following topics:

In contemporary India, the regional state of West Bengal has often been perceived as somewhat of an aberration in the wider context of a rather chaotic democracy, as the Left Front (spearheaded by the Communist Party of India-Marxist, CPIM) demonstrated a rare instance of political stability, decisively…

Spectroscopic studies on fluorescent single molecules in organic condensed matter does not only provide information about the molecule itself, but also its near environment. By suppression of phonon-induced broadening of spectral lines through cooling to low temperatures, small changes in the spectral…

Geometric phases lead to a nontrivial interference result when an electron's different quantum mechanical paths choices encircle a magnetic coil in an Aharonov-Bohm experiment.

The Altai region has yielded a cluster of Middle and Upper Paleolithic stratified sites that have been recently excavated using a multidisciplinary approach.

We have conducted a full spectral line survey of the 3-13 micron region of two massive protostars, AFGL 2591 and AFGL 2136, for the first time at high spectral resolution.

On 29 april 2020, Beth Van Schaack defended her thesis 'Imagining Justice for Syria: Water Always Finds Its Way'. The doctoral research was supervised by Prof. C. Stahn.

This research delves into the unique cultural approach of the Tenggerese people, an Indigenous community in East Java, Indonesia, regarding elderly care. It focuses on their traditional practices of bakti (‘filial piety’) and sayan (‘mutual aid’), deeply ingrained in the community's lifestyle and va…
