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

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…

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.

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

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.

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…

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?

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…

Leiden is a lively university city that’s brimming with history and boasts a student culture that’s tangible just about everywhere. Read on to discover what Leiden has to offer and get a foretaste of what you can expect.

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.'

Leiden University enjoys an excellent worldwide reputation, built on more than four centuries of outstanding teaching and research. The university has two locations: Leiden and The Hague. Our International Studies programme is located in The Hague, a centre of international and national policy making…

Studying in The Hague can make a big difference. The Hague is proud to be known as the international city of peace, justice and security. The city is full of opportunity and is a fantastic student city.

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.

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 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.

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 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…

Nine Honours Class students pitched their plans on 3 March to make the city of Leiden safer, more transparent and more democratic. In this version of 'Dragons Den' headed by Professor Job Cohen the students were tested on their plans and their mettle.

Researchers at LUMC are trying to decipher the biological clock. This knowledge can help deal with luxury problems, such as jetlag, but can also counter diseases. Molecular neurobiologist Erno Vreugdenhil explains.

Industrial ecologists Stefano Cucurachi and Flora Siebler are part of the new consortium PROGENY, which received 3.6 million euros from the European Commission. PROGENY is an exciting project that will study the possibilities of soap films for innovations, such as ultra-thin screens.

The enthusiastic finalists of the Sustainable Business Battle proved that sustainability and business can go together well. Fire in their bellies, they pitched their green solutions, ranging from an Energy Race app for DUWO to a cycle parking facility covered with plants at the Bio Science Park.

A more efficient solar panel sounds great. But what if these new panels consume more toxic materials, or their production consumes a lot of energy? Leiden environmental scientists, together with colleagues from the Fraunhofer ISE, address this multifaceted question in a new publication in the prestigious…

There are currently two projects in Coptic Studies that are supported by the NVIC. Both are directed by Dr. Karel Innemee and both take place in the Wadi Natrun.

Every student learns about science, but those of the Master Honours Class ‘The Academic Life’ went an extra mile. They learned all the ins-and-outs of academia and rounded off this successful lecture series with a final session on evaluating scientific research.

We asked a lot of everyone last year. The Personnel Monitor showed that the workload was high in 2022 and Covid took its toll. I therefore think everyone deserves some downtime. Time away from the daily grind.
