Leiden University offers support in the different stages of your research lifecycle.

You may know it by the umbrella term 'citizen science'. You may also use terms such as volunteer mapping, patient co-researcher, or even community engaged learning to describe participatory practices in your research or teaching. No matter what you call it, there’s plenty going on when it comes to this…

Children are perfect scientists: they are bursting with curiosity, they want to know how the world works and they go exploring every day. Yet many children barely get a chance to be engaged in science. A number of scientists from the Young Academy want to change that. They have received 150,000 euros…

The Heritage Quest project is a citizen science project in which volunteers participate in archaeological research.

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 &…

OSCL is a learning community where anyone associated with Leiden University can learn and talk about open science practices. Example events are Open Science cafés, workshops, and walk-in-hours. The what Open science is an umbrella term for an approach to science that aims to make scientific…

PathOS aims to contribute to a better understanding and measurement of Open Science impacts and their causal mechanisms. This is pivotal in order to develop effective OS policy in the EU (European Union). It will do so by collecting concrete evidence of OS effects, by studying the pathways of OS practices,…

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.…

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…

The Dutch Research Council (NWO) has rewarded four projects in which Leiden researchers are bringing science and society closer together. What are these projects?

In this article, Martin Sievert and Jonas Bruder investigated whether and how administrative burdens influences citizens' perceptions of welfare policies and attitudes towards beneficiaries.

Politics is about the authorised allocation of values: who gets what, when and how much? This question is relevant at many different levels, in many different places and in very different ways.

This article aims to contribute to the debate about citizen involvement in medical and social issues by studying co-production initiatives in The Hague.

Perhaps you are completely new to the concept of Liberal Arts and Sciences, or perhaps you are familiar with the Liberal Arts colleges of the United States. So, what actually is Liberal Arts & Sciences, and why has it become so popular in the Netherlands in recent years?

People are keen to make a contribution that will be valuable for scientific research. Many thousands are taking part in the Major Flu Survey. Leiden researcher Anne Land is publishing on this subject in the Journal of Science Communication.

This article studies the influence of framing on preferences for cooperation with the EU.

This project explores how the populations of the historically contiguous towns of Nusaybin, Turkey and Qamishle, Syria articulate citizenship in the everyday.

In recent years, the question why citizens (do not) support democratic innovations has attracted increasing academic attention. In this research note, Van Der Does & Kantorowicz for the first time empirically verify what drives citizens’ instrumental considerations in their evaluation of a DI.

Moritz Jesse, Associate Professor of EU Law at the Europa Institute, has published his book, “The Civic Citizens of Europe: The Legal Potential for Immigrant Integration in the EU, Belgium, Germany, and the United Kingdom”.

Principles of Environmental Sciences provides a comprehensive picture of the principles, concepts and methods that are applicable to problems originating from the interaction between the living and non-living environment and mankind. Both the analysis of such problems and the way solutions to environmental…

Do you have any questions about the Citizen Science Lab? Are you looking to participate in a local citizen science project? Do you want to establish a project for yourself and could use some support?

How can the Indonesian National Ombudsman make the transition from autonomous to responsive justice in view of the day-to-day challenges it is faced with?

Is it possible to formulate a new conceptual foundation for attributing an evaluative role to historiography of science, without relinquishing the historiographic sensitivity of recent work in the discipline?

This article investigates the causes and examines how differing public perceptions of the rule of law contribute to this trend.

What tools can be applied to measure the output, outcome and impact of science communication efficiently and effectively?

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…

One of the goals of the Citizen Science lab is to be an incubator for citizen science projects. Over the years, the lab has been involved in creating and supporting various projects. Get inspired!

How can we bridge the gap between experts and the general public?

The mission of the Plant Science research programme is to contribute to the sustainable production of high quality crops, flowers and high-value bio-based products. This is realised by generating fundamental knowledge of basic biological processes related to development of plants and their interaction…

Sarah Giest, Assistant Professor at Leiden Univeristy, researched the topic of regulatory and market structures that affect nudge implementation by private actors, captured by the ‘budge’ idea.

In the research programme Microbial Sciences we perform state-of-the-art research in the field of biotechnology and microbial sciences.

Although smartphones and other consumer cameras are increasingly used for scientific applications like citizen science, it’s still difficult to compare and combine data from different devices. PhD student Olivier Burggraaff developed a new easy-to-use standardised method which makes it possible for…

There are eight institutes at the Faculty of Mathematics and Natural Sciences:

In 2019 citizen scientists inspected elevation maps of the Veluwe region and discovered several thousand potential new archaeological structures. The project started as exploration into the potential of citizen science in Dutch archaeology, but developed into a fully flexed project in which citizen…

The master's specialisation Data Science: Computer Science at Leiden University provides students thorough knowledge and understanding of statistical and computational aspects of data analysis, including their application in databases, advances in data mining, networks, pattern recognition, and deep…

We perform multidisciplinary research at molecular, cellular, and organismal levels of animal biology to increase fundamental understanding of health and disease.

We are very happy to welcome you to spend a semester or year studying with us in the Faculty of Science. Here you will find information on your course schedules and course and exam enrolment.
