We investigate the physics and design of mechanical metamaterial, intricately sculpted materials with properties set by their architecture.

We investigate emergent structures and dynamics of soft materials self-assembled from microscopic constituents.

Psychology Lab on Wheels makes science accessible for everyone. On Monday 24 June, we will be back with our mobile lab at the Old Observatory near the Singelpark in Leiden. Join our research to learn to better recognise emotions with a Serious game and read more about participant Maxime and game developer…

We are a dynamic research group at the Leiden Institute of Physics. Our aim is to explore and understand quantum materials, including strange metals, high-temperature superconductors, and quantum critical electron matter.

Since itch and pain can be very burdensome, especially when individuals suffer from (either of) these symptoms chronically, it is important to know the factors by which these sensations are influenced. It becomes more and more clear that psychological factors play an important role in the experience…

Our group explores the larger domain of quantum measurement. In particular we investigate two themes that are closely connected: The detection of specially prepared quantum states of light and understanding and characterizing quantum photon detectors.

Study information

The relevance of intentionality to the interpretation of Aristotle was first suggested by Brentano in his Psychology from an Empirical Standpoint. Here we take our starting point from Brentano and investigate how Brentano’s concept of intentionality is rooted in Aristotle.

We study cell-fate decision-making using embryonic stem cells as a model system. Stem cells integrate a large number of cues to direct their development into a great variety of cell types.

The Leiden HANDS!Lab for Sign Languages and Deaf Studies hosts research activities in the area of sign language linguistics and Deaf studies, with a focus on Africa. In addition to various research projects, we have our Deaf studies lecture Series in International Sign and offer various regular and…

Kim de Jong, Jaime Delgadillo, and Michael Barkham offer valuable insights in their book 'Routine Outcome Monitoring and Feedback in Psychological Therapies' on how therapists and trainees can use feedback to inform treatment decisions and, ultimately, enhance patient outcomes.

The philosopher and psychologist G.F. Stout was the teacher of Moore and Russell around 1894. This book shows that Stout's ideas have played a role in Moore and Russell's development from their early idealism towards analytic realism, where Stout's ideas often find their origin in early phenomenolog…

Social and Behavioural Sciences, Psychology

Using an interdisciplinary experimental approach grounded in behavioral economics and personality psychology, we identify an antisocial personality profile and examine its role across strategic contexts.

Research in the Daniela Kraft Lab focuses on self-assembly in biological and soft matter systems, ranging from anisotropic colloidal particles to lipid membranes, emulsions, and viruses.

Social anxiety runs in families, but the neurobiology underlying this genetic vulnerability is until now largely unknown. The unique Leiden Family Lab study on Social Anxiety Disorder (LFLSAD) aims to broaden our knowledge with respect to this genetic susceptibility.

Advancing the understanding of the interaction of light and matter on the single-quantum level is important for near-future quantum technologies but also to answer fundamental questions.

The research program of the QO group has three leading themes: Optical Physics, Quantum Optics, and Photon-Matter Interactions. We work mostly at the boundaries between these themes with entanglement as a bridging and binding agent.

In our lab, we investigate the physics and material properties of low-dimensional systems.

This year will see the start of not one but two citizen science projects in Leiden and The Hague. This is the outcome of a large survey among residents and researchers in both university cities. The Citizen Science Lab will help the winners implement their ideas, with support from the University and…

Study information

Research in the van Exter lab focuses on quantum aspects of light and light-matter interaction. One of our long-term goals is to develop a reliable quantum memory, based on a single emitter in an open micro cavity.

We explore the possibilities to combine magnetic resonance techniques with atomic force microscopy together in a single microscope: the MRI-AFM, also called Magnetic Resonance Force Microscopy (MRFM).

Brazil is one of the world's largest emerging economies, but more is needed if it is to use this economic power for all parts of Brazilian society. This will be the subject of Professor of Brazilian Studies Edmund Amann's inaugural lecture on 20 November.

With the new SSH labs and their organisation, the lab coordinators will also fulfill a new role. An interfaculty workgroup -consisting of staff from Psychology, Pedagogical Sciences, Humanities and SOLO - is currently discussing the new role of the lab coordinators, and how the lab coordinators can…

How do learners engage during project-based learning (PBL) and what is the impact of PBL on their learning outcomes?

This article examines leadership encouragement and psychological safety as antecedents of prosocial rule-breaking (PSRB) behaviour.

On 22 June 2022, the research group on Institutions for Conflict Resolution organised its second annual overarching PhD lab. During this meeting, the PhD researchers connected to COI presented the current status of their research projects.

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.

While tens of thousands of visitors dance to deafening music, a team of Leiden psychologists are trying to collect data for their research at Lowlands. How do festivalgoers experience a virtual trip? And what role do factors such as too little sleep and whether they have experience with psychedelics…

The Biotech Training Facility (BTF) on the Leiden Bio Science Park is now officially open. Professionals and students can practise their skills and learn new competences in the field of life sciences in this fully equipped training centre with laboratories, clean rooms and technical areas.

The department of World Archaeology combines research and education about regions all over the world, from Human Origins to the Middle Ages, and from Europe, to Asia, Africa and the America’s. That broad range in time and space makes the department a dynamic pluriform community with many different approaches,…

When it comes to languages and cultures, Leiden University is the university. The global expertise present places our university at the top. In Leiden and The Hague, we study languages and cultures from all regions of the world and from prehistory to the present day. In this way we create a broad view…

People who have taken antibiotics in the past three months pay more attention to negative facial expressions, according to research by postdoc Katerina Johnson and assistant professor Laura Steenbergen. This may explain how antibiotics increase the risk of developing depression.
