The Leiden Institute of Education and Child Studies aims to conduct high-quality research that addresses major social issues. This inspires its BSc, MSc and PhD programmes.

The master’s programme Mathematics at Leiden University focuses on analysis, probability and statistics, number theory and (arithmetic) geometry. It offers five specialisations ranging from Applied Mathematics to Mathematics and Business Studies.

Terrorist groups adapt to environmental changes to maintain power. This project provides new insights by developing a theory of strategic target selection and using big data analytics and machine learning to test these hypotheses.

Research at Leiden Observatory spans the full width of modern astrophysical enquiry. It is based on observation, theory, simulation, and experiment. Two broad clusters characterize the ongoing research. Within each theme, researchers carry out their personal and specialized research programme. The two…

Research at Leiden Law School means research at the highest level.

We are committed to empowering the continuous development of higher education. With a team of multidisciplinary experts, LLInC supports innovative and high-quality education, within Leiden University and in partnership with academic and social organisations.

With a master’s degree in ICT in Business (last intake in February 2025), job opportunities are excellent and diverse, ranging from consultancy to IT management and from entrepreneurship to PhD research. Our alumni have found jobs within Europe and outside, in industry, government and universities.

The history of sign languages of deaf people is severely understudied. The historical linguistics of sign languages offers a fundamentally new perspective on the history of human languages. This project addresses the dearth of knowledge about historical sign language linguistics through a large-scale…

We are cosmologists, in other words we use physics to study the Universe, how it started and evolved into the structure that we observe around us.

Research projects for students of the University of Leiden and other Dutch Universities are often available at the MacBio group. The research lines are also described in the Research section. For details of specific projects contact the supervisor (Ubbink, Dame, Boyle, Jeuken or Wentink).

The transition to new and renewable energy sources should be completed by 2050. Researchers in various disciplines at Leiden University are conducting unique research that will help us make this transition and reduce CO2 emissions.

Central in coordination and organometallic chemistry is the synthesis of new chelating ligands, the synthesis and characterization of metal complexes with these ligands, and the study of their properties. An important goal in my research is to create understanding of the relation between the structures…

The "Van Marum Colloquia" are a collaborative lecture series between the LION and LIC institutes, focusing on fundamental and applied surface science.

This regulation – also known as the AI Act – aims to ensure that AI systems sold and used in the EU are safe and consistent with existing fundamental rights legislation and Union values. AI harvests its factual material on the Internet, but in some cases it can be misleading. This is sufficient reason…

The Open University and Leiden University will join forces to offer a (Dutch-taught) Joint Legal Technologies Program for professionals. In doing so, they can provide the advanced legal informatics training that is necessary in our rapidly digitising society. The joint program is a further development…

In this project, we will study the genetic and environmental drivers of woodiness and stem lignification at the level of plant‐to‐gene‐to‐molecule.

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 Secular Outlook describes what moral and political secularism means. It paints the image of a world view in which state and religion are kept well separated.

The ability to create objects and structures with our hands has been essential to human development. This ability is something modern society is at risk of losing. Leiden archaeologists gather knowledge about ancient processes of ‘making and creating’ over the centuries, knowledge that helps our current…

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…

Many important topics in computer science, such as the correctness of software, the efficiency of algorithms and the modeling of complicated systems, depend on sound theoretical underpinnings. In the Theory group, we study these fundamental building blocks and develop verification methods to prove system…

Plants could be regarded as small chemical factories, which produce chemical substances via photosynthesis. If we can imitate photosynthesis in an artificial system, we can make clean fuels and materials out of sunlight and CO2. Huub de Groot is very close to designing a system of this kind.

Project Announcement: ‘EU human-centered digital transformation’ (2023 – 2027) funded by Leiden University Starting Grant In Spring 2023, Simona Demková and Daniel Mândrescu from the Europa Institute secured the new Leiden University Starting Grant, valued at 240,000 EUR, for a collaborative project:…

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…

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…
