Artificial photosynthesis has recognised potential to produce green and sustainable fuels from earth-abundant resources such as water, carbon dioxide (CO2), and sunlight.

In recent decades, climate change has led to more frequent and severe drought events, causing serious consequences such as increased forest mortality and significant crop yield losses. Understanding how drought affects plants, especially economically important herbaceous species, is crucial for predicting…

Cardiovascular diseases are the primary cause of death in the world with atherosclerosis as primary underlying cause.

A seven-metre glass tunnel, filled with running water, and equipped with speakers and cameras. An artificial river for investigating what light and sound pollution do to migrating fish.

Beneficial plant-associated microbiota, particularly those inhabiting the rhizosphere, contribute substantially to plant health through pathogen suppression, stimulation of plant defence responses, and enhanced nutrient acquisition.

Are you eager to dive into a cutting-edge approach to innovation? Do you want to explore how frugality and frugal innovation can drive sustainability? And are you up for an international, real-life challenge? If so, this Leiden-Delft-Erasmus (LDE) minor on frugal innovation is for you!

The research described in this thesis focused on identifying novel drug targets and synergistic combinations for triple-negative breast cancer (TNBC), a virulent subtype of breast cancer with a dismal prognosis and limited therapeutic options.

This thesis systematically studies the physicochemical properties of non-planar, propeller-shaped, polycyclic aromatic hydrocarbons. The synthesis of several so-called propellerenes is described on a gram scale, using optimized procedures aimed at using less hazardous reagents and reducing the amount…

The main goal of the THEOR CHEM group, headed by Prof. Geert-Jan Kroes, is to characterize, and to accurately predict the outcome of chemical reactions at gas-solid and liquid-solid interfaces. Here the solid surface is typically a metal or an ice surface. These goals are important to many areas in…

Although there is considerable evidence that nature in the city is beneficial to both people and animals, we still do not have an overall picture of those benefits. To rectify that, a Leiden PhD candidate and a student – armed with a cargo bike – are using The Hague as a life-size laboratory.

This project uses archaeological, literary and epigraphic evidence to investigate urban development in Roman-period North Africa, compiling this in a GIS-linked database in order to analyse the development of urban settlement spatially over time.

On the basis of the characteristic aspects of a picture, certain computers can tell us what the picture is showing. They can learn this in the same way that young children are able to learn to recognize images. Further improving these techniques opens the way to a whole range of new applications. Biology…

The researchers in the World Archaeology department of the Faculty of Archaeology concentrate on a range of different periods and regions: from humanity’s origins to the Middle Ages and the modern age, and from Asia to South America.

The Food citizens? team has included two post-docs, three Ph.D. candidates and two research assistants working with the Principal Investigator. The Winter School involved nine Masters and Ph.D. candidates from the universities of Bologna, Gothenburg, Kaunas, Leiden, Louvain, Tromsø, Turin and Utrech…

Between foraging and farming: an extended broad spectrum of papers presented to Leendert Louwe Kooijmans.

NL-BioImaging AM is a distributed research infrastructure aimed at promoting progress in the most cutting edge microscopy technologies and providing open access to these technologies to a broad community of academic and industrial users. All Netherlands bio(medical) microscopy centers participate.

How were the Russians, under early modern conditions, able to incorporate this distant, undeveloped and, because frequent nomadic attacks, dangerous territory? And what role did the Kolyvan-Voskresensk plants play in this process?

Leiden University’s new ‘Europe Hub’ is an interdisciplinary platform that showcases the university’s research and teaching expertise and capacities on Europe’s societal and governance challenges.

‘Fernweh: Crossing borders and connecting people in archaeological heritage management ’

If you follow the western media, you are likely to think of ‘Africa’ as the continent of origin of desperate migrants, a continent of hunger and disease and a breeding ground for international terrorism. But if you want to see the bigger picture, you should look no further than the African Studies scholars…

The new interdisciplinary bachelor's program in Science for Sustainable Societies starts in the 2025-2026 academic year.

Africa needs a narrative that is consistent with the developments that are taking place all around the continent. In these developments, talented youth, creative tech hubs, and leapfrogging play a big role. We need to invest accordingly.

Fearing a trade-off with economic growth, countries feel discouraged to cut their CO2 emissions. But do the two really not go together? Environmental scientist Ranran Wang and her colleagues investigated the relationship between economic growth and CO2 emissions in 73 countries from 1970 to 2016. Wang:…

Arbeidsuitbuiting van migranten wordt als een vorm van het strafrechtelijke delict mensenhandel beschouwd. De rechtspositie van de slachtoffers is mede daardoor ondergeschikt aan de strafrechtelijke procedure. Dat kan en moet anders, stelt Gerrie Lodder in haar proefschrift. Promotie op 21 april 202…

In January 2020, the team took a break from their respective field sites and travelled back to Leiden to take stock of their research progress and to host its third Advisory Board meeting at their home institution, the Institute of Cultural Anthropology and Development Sociology of Leiden Universit…

The Rutte-III coalition agreement has been presented and the commentary is flooding in. Public administration experts Arco Timmermans and Gerard Breeman examined the new agreement – as they have done for every coalition agreement since 1963 - and made a systematic analysis of it: it is very much about…

It is often thought that immigration threatens the solidarity on which redistribution relies. But looking at the post-war period, PhD candidate Emily Anne Wolff finds that this is not the case.

The "Van Marum Colloquia" are a collaborative lecture series between the LION and LIC institutes, focusing on fundamental and applied surface science.

Electrochemist Marc Koper has been awarded an ERC Advanced Grant of 2.5 million euros for research into chemical reactions driven by electrodes and electricity. He hopes that new insights will make it into the textbooks and help design green processes, such as making fuel from greenhouse gas.

The first of April was the official start of Phase II of the collaborative “PCAD4Cod”-project on the effect of sound on fish populations.
