Kaveh Lahabi's lab explores the exotic physics of quantum materials, whose underlying physics seems to have more in common with elementary particles and black holes, than ordinary metals and semiconductors.

Our current research focusses on the exploration of the Universe using the neutrino. This neutral, almost massless and only weakly interacting particle can open a window to the distant Universe and also dense regions from which photons cannot escape.

How do societies move forward with sustainable, effective and efficient management of Earth's water resources?

Public management scholars have long debated public and private sector differences. However, the generalizability of empirical results has been limited due to the shortage of cross-national studies.

In the Leiden Municipality Challenge, 25 students investigated how Leiden could become more sustainable. In doing so, they enlisted the help of the city's citizens. 'When citizens themselves participate in the research process, they have a better understanding of how science works.'

Jan Aart Scholte, Professor Global Transformations and Governance Challenges, is a co-author of this book that offers the first full comparative study of citizen and elite legitimacy beliefs toward global governance.

Intrigued by the way cells autonomously regulate their fate, we strive to understand and visualize cellular processes as the basis of Cell Signaling.

How do humans construct their self?

Since the early 1990s, one can isolate the optical signal of a single molecule and single-molecule spectroscopy has quickly grown into an important research field.

The Astronomy & Society Group provides the focus for Leiden Observatory’s aim to engage the public with the wonders of the universe and share the scientific, technological, cultural and educational aspects of astronomy with society.

Democratic citizenship refers to the capacity and willingness of citizens to actively influence the functioning of state institutions. While considered a vital correlate of democratization and the rule of law, its largely western-oriented literature rarely studies the forms of democratic citizenship…

The VICI research project Citizenship Discourses in the Early Middle Ages, led by Els Rose (Universiteit Utrecht), published a new book: Els Rose, Robert Flierman en Merel de Bruin-van de Beek, red., City, Citizen, Citizenship, 400–1500. A Comparative Approach (Londen: Palgrave-Macmillan, 2024). It…

In the Aarts lab we combine or structure materials, mostly in thin film form, in such a way that the hybrid has different and novel properties or functionalities.

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

What motivates citizen scientists in the Schone Rivieren project to contribute? How does their motivation, attitude and knowledge change over the years? Are there differences in motivation and attitude between different groups of volunteers (clean up vs. monitoring; long-term vs. short-term)?

Chromatin is an ubiquitous protein-DNA complex that forms the structural basis of DNA condensation in all eukaryotic organisms.

The Divide & Quantum (D&Q) project offers various solutions to harness the power of quantum computers in the near term, proposing entire pipelines, from theoretical research, via implementation to real-world case studies in a number of disciplines, to science communication with the broader society.…

A place where scientists and students from Leiden University and residents of The Hague come together to create innovative solutions for sustainable living in the city: that's what the Sustainable City Lab aims to be. When we talk about "sustainable living" we think of many different things. For example:…

NestWatch uses smart birdhouses to research how the city affects the development of young birds.

Subproject of the NWO Smart Culture Grant research project 'The Critical Visitor'.

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

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

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.

Cristina Grasseni’s project

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.

We work with groups and individuals, stakeholders and centers of excellence to create an environment in which Open Science and Recognition & Rewards can flourish.

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…

The research group Science Communication and Society has been physically within the Institute of Biology (IBL) since 2012 and has become a formal part of the institute in 2018. The mission of this group is understanding how science communication works to improve the interaction between science and s…

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.

The idea of citizens and public professionals collaborating to provide public services has widely spread in several countries around the globe. Co-production is often presented as the go-to solution for challenges like a legitimacy crisis of both the government and the market, and financial concerns.…

Data science offers exciting new instruments for governments to reach out to citizens, for example by using data-driven information channels, providing real-time simulations, or personalizing services based on citizen data. At the same time, the possibilities and use of data science methods can have…

Government impartiality is considered a core feature of quality of government, and one that leads to favorable macro‐level outcomes. We have limited knowledge, however, of how impartiality affects citizens' perceptions of public service quality. In particular, we do not know how the impacts of impartiality…

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.

With the emergence of new methods and technologies such as improved DNA analysis and big data, archaeological research has changed radically in recent decades. The researchers from the Department of Archaeological Sciences at the Faculty of Archaeology use new scientific knowledge to answer fundamental…

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.

It is often claimed that social media can contribute to democratic decision-making by bringing politicians and citizens into dialogue with one another. But is this potential always realised, and how? Most researchers look at politicians and their online communication strategies. In this New Media &…
