In medical and psychological sciences, little research has been specifically conducted on women. Hormonal fluctuations were considered too intricate. Yes, research into sex and gender differences is complex, acknowledge neuroscientists Ellen de Bruijn and Lara Wierenga, but that’s precisely why it's…

Thanks to a clever research method, progress is being made in the quest for better tuberculosis medications. Within an American consortium that received a 30 million dollars grant, Leiden researcher Rob van Wijk plays a significant role. ‘The next breakthrough in tuberculosis research will come much…

The ‘Amorphophallus titanum’ at the Hortus botanicus Leiden is blooming. This Titan Arum, also known as the ‘giant penis plant’, last flowered in 2009.

We depend on nature for so many things: from clean water, wood and food to carbon absorption, water purification and coastal protection, as well as for relaxation, inspiration and identity. Nevertheless, our modern world putting increasing pressure on these ecosystem services. Leiden researchers investigate…

Here you'll find selected publications and media attention from our group.

Terrorism experts Daan Weggemans (Leiden University) and Beatrice de Graaf (Utrecht University) conducted one of the first scientific studies on the societal reintegration of jihadist former detainees. They showed that the reintegration process isn't without problems. Their conlusions are presented…

In this project, we will study the genetic and environmental drivers of woodiness and stem lignification at the level of plant‐to‐gene‐to‐molecule.

‘Tell me something I don’t know,’ said skating coach Jac Orie to Leiden data scientist Arno Knobbe. And he did. Knobbe and his colleagues now assist athletes in all kinds of ways with the help of data mining.

Tracking early human behaviour through plant processing and -exploitation.

Over the past century, the world population has grown exponentially, as has our need for energy and raw materials. If we wish to continue to live prosperously in the future, we have to radically restructure our economy and consumption. Scientific research shows us how to do this.

Through metabolism, biochemical processes give rise to the complexity of life. Acquired and inborn errors in metabolism underlie many diseases occurring in man. The challenge for present day medical biochemistry is to find, and integrate, pieces of information at molecular, cell and organismal level…

A neural network mimics how our brain works. Evolutionary algorithms use the principle of natural selection to solve complex problems. This kind of 'natural computing' is being used to improve the diagnosis of Parkinson's disease or the production of steel.

The goal of hit and lead optimization is to optimize suitable chemical starting points that can modulate a drug target. The methods and technologies used are similar to those in Hit Discovery, but once the compound has shown activity in an animal model, it moves from 'hit' to 'lead.'

In his dissertation Gabriel Paiuk explores the variable ways in which what is heard is formed. To address this, he postulates a novel concept of sound image in a post-anthropocentric context in which both mind and material artefacts are instances across which the image occurs, rather than hosts on which…

An overview of the research at the Cancer Dug Target Discovery group.

1) How natural cycles and activities are interconnected for building the time in one community? 2) What perceptions of Ñuu Dzaui peoples about their landscape can be connected with precolonial times?

Leiden has much to celebrate: first, 450 years of the Relief of Leiden and then 450 years of Leiden University. And that is no coincidence.

What is the effect of light at night on plant phenology and physiology, and how does this affect plant interactions with other species?

The Research Group 'Violence and Violence Prevention' studies interpersonal violence. We seek to better understand the dynamics underlying interpersonal conflict.

This is an Erasmus+ International Credit Mobility project of Leiden Law School with Shandong University in Qingdao.

AI-tools are introduced within our infrastructure, work, communication, interpersonal relations, economy, democracy, health, science etcetera, to overcome limitations and/or increase efficiency, speed, reliability, convenience. Given the impacts across society, AI requires broad action and reflection…

The majority of scientists, from archaeologists through to zoologists, collect huge volumes of data. Their massive databases contain large amounts of information which is difficult for humans to filter. With a solid grounding in statistics, we can develop algorithms for analysing and identifying patterns…

Leiden University's interdisciplinary research programme SAILS funds young interdisciplinary scientists working at the intersection of AI and other fields. How do these researchers experience the work?

You will be advised by a PhD Advisory Committee (PAC) that is appointed especially for you. Typically the members of the PAC are: the LACDR Scientific Director, your promotor(s), if applicable, your co-promotor(s) and an external advisor.

The main research theme in the group of Dennis Hetterscheid is to understand and mimic bioinorganic multi-electron processes that are relevant to our future energy infrastructure. Reduction of protons generates hydrogen that can be used as a chemical fuel. Alternatively to gaseous hydrogen, the reduction…

My ERC Starting Grant, funded with €1.5 million for 5 years as part of the Horizon 2020 research and innovation program, is focused on building the early warning system WARN-D to reliably forecast depression in young adults before it occurs. Why depression, and why prediction?

What was the function of the Dutch Protestant Church in Sri Lankan society? Why did people relate to the Church and how did conversion influence their life course?

An overview of awards and prizes granted to our staff and students in 2022, as well as special appointments at Leiden University and other institutions.

Over the past century, the world population has grown exponentially, as has our need for energy and raw materials. If we wish to continue to live prosperously in the future, we have to radically restructure our economy and consumption. Scientific research shows us how to do this.

On this page you find all the ways through which the Institute of Psychology aims to foster Open Science.

Since the late 1990s Leiden University has been located in two cities: Leiden and The Hague. Leiden is where the University was founded and still forms its heart, with six of the seven faculties being housed there. The faculty of Governance and Global Affairs is located in The Hague and most of the…

New housing in old labs and striking architecture for University buildings and high-tech companies, not to mention waterside parks. An exhibition in Oude UB shows the radical changes that are in store for the Leiden Bio Science Park over the coming years.

On 20 February 2018, Simone van der Hof will give a lecture on the use of AI in combating online sexual abuse of children at the Academy of European Law (ERA) in Trier during the seminar The Life Cycle or Electronic Evidence - Handling E-Evidence in Child Sex Abuse Material.

The Medieval Institute at Western Michigan University is delighted to host the Wallace Johnson Program for First Book Authors, a program designed to provide support and mentorship to scholars working towards the publication of their first book on the law and legal culture of the early middle ages. In…

Netherlands and China can learn from each other to handle household and livestock wastewater more sensibly. In the FOREWARD project, scientists from Leiden, Wageningen, and China are working together with local partners on feasible solutions that advance the environment, health, and economy.

Medicines can work even if they have no active ingredient. The first international scientific conference on placebos will take place in Leiden from 2 to 4 April. Placebo researcher Andrea Evers, who is also chairing the conference, answers some pressing questions.

The Leiden University College team behind the Learning Mindset project has been nominated for the Dutch Higher Education Award, an award for innovative teaching in higher education. The Ministry of Education, Culture and Science announced this on 15 March.

The map application includes information from old and new buildings archaeological projects. This makes it possible to investigate whether water facilities (wells, cisterns) and waste facilities (cesspits, sewers) were the privilege of Leiden’s wealthy elite in the late 16th and 17th centuries or whether…
