(1) What are the institutional factors that influence AI adoption and implementation? and (2) How does AI reshape the exercise of administrative discretion within public organisations, and how do adoption and implementation choices moderate these effects?

Serious forms of anxiety concerning other people’s opinions can hinder teenagers at school in social interactions or carrying out tasks. Psychologist Anne Miers is looking for ways to reduce this so-called ‘social anxiety’.

A central and much debated topic in the study of language acquisition concerns the nature of the learning mechanisms that are required. Are the computational and learning mechanisms that guide learning about language structure special and specific to language or humans?

The research question is that unconscious perseverative cognition (UPC) is responsible for a considerable part of cardiovascular (CV) activity that occurs even in the absence of threats and other stressors that one may encounter in one’s daily life.

Treatment and care for cancer patients is becoming increasingly advanced. For example, surgeons can now perform operations with much greater precision, and therapeutic vaccines are being developed to prompt the patient’s immune system to fight cancer. Work is also being done on better early diagnostics,…

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…

This project has two main aims: I. Determine when novelty promotes fear extinction. II. Discover the neurobiological mechanisms underlying these effects.

Huub de Groot is professor in Biophysical Organic Chemistry. With his team he works in the field of photosynthesis and artificial photosynthesis. The molecular basis for photosynthesis is formed by protein complexes and organelles that contain chlorophyll molecules. The antenna systems herein capture…

Positive expectations can influence sensations of itch and evoke placebo effects, whereas negative expectations can trigger nocebo effects in itch. There is evidence that placebo effects can occur even when people know that they are taking a placebo. Little is known about how these so-called open-label…

People are less willing to give up an interest when in a negotiation situation than when they can do it of their own free will, as Leiden University psychologist Eric van Dijk discovered. Knowledge of this kind can be used by policy makers, for instance, to motivate people to adopt certain desirable…

The need for novel drugs as well as innovations in their development and application is as urgent as ever. Below we present our vision , mission, and our key research areas.

Using N2 dissociation on Ru(0001) as a representative showcase (for catalysts employed in the Haber-Bosch process), we have shown for the first time that non-adiabatic effects can substantially reduce a molecule’s dissociation probability on a metal surface. These effects are currently completely unaccounted…

Leiden researchers Fenneke Sysling and Joris van der Voet will be admitted to the Royal Netherlands Academy of Arts and Sciences’ The Young Academy.

In their quest for materials that conduct electricity without resistance at moderate temperatures, scientists usually work on their chemical make-up. Now Leiden physicists have come up with a radically new approach: pinching holes in a periodic pattern. Publication in SciPost.

An MRI scanner is much more than a machine alone. It is an extremely versatile technique that provides numerous opportunities for finding out more about the workings of the human brain, says Thijs van Osch, Professor of Radiology, with a particular emphasis on experimental cerebrovascular imaging. Inaugural…

As of 1 July, Professor of Mathematical Biology Roeland Merks has got a full appointment at Leiden University. Before this expansion, he worked one day a week at the Mathematical Institute (MI). Merks will work half of his full appointment at the MI and the other half at the Institute of Biology Leiden…

Political scientist Femke Bakker (Leiden University) is going to investigate whether meditation affects political behaviour. Bakker has been awarded a PEACE Grant by the Mind & Life Institute, which enables her to conduct innovative, experimental research. The aim is an answer to the question whether…

This year, the annual meeting of the SSE-SEG-SAA addressed the topic of “norms and alternatives”. Prof. dr. Cristina Grasseni and lecturer Janine Prins participated…

'Jammed' is released as a limited edition with music composed, recorded and mixed in the Institute of Sonology (Royal Conservatoire, The Hague) between January and June 2022.

Physicists understand little about quantum matter, which is a building block of future quantum computers. Theorists have now discovered that black holes with ‘dreadlocks’ harbor a similarly exotic order pattern, which makes calculations on quantum matter easier. Publication in Physical Review Letter…

Ross Gildea has won the Institute of Political Science Research Master Thesis Prize 2016. ‘The Political Psychology of Humanitarian Issue (Non-)Adoption in International Politics’ is the crowning achievement of Gildea’s work as a MSc student. The thesis, according to the jury, stands out as a ‘fine…

Two excellent young chemists, Jeroen Codée and Sander van Kasteren, have received an ECHO grant for €260,000 from the Netherlands Organisation for Scientific Research (NWO). This funding will allow them to begin their research projects.
