The focus of our theoretical physics research is the nature of macroscopic matter that is in one or the other way still in the grip of quantum physics.

Our research primarily focuses on the early universe and its origins in theories that go beyond the Standard Model of particle physics.

Our world is shrinking, or at least our electronic devices are. From PCs to mobile phones: everything is smaller and thinner. The smaller the chip, the better it can conduct electricity and pass on information.

The research group on Diplomacy and Global Affairs studies international diplomacy, international organisation, global, transnational, multi-level and comparative governance.

To be eligible for Public International Law at Leiden University, you must meet the following admission requirements.

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…

My work is motivated by the necessity to extend Standard Model of Particle Physics in order to explain three observed phenomena that this great theory fails to accommodate

This minor focuses on how our thoughts, emotions and behaviour are influenced by other people, and how we influence other people.

Health inequities, obesity among children, loneliness, performance stress among youngsters. What are the drivers behind such ‘wicked problems’ and how might they be related? This interdisciplinary minor offers you the possibility to work with societal partners to gain a deeper understanding of real-life…

We are interested in understanding the mechanics of soft materials, of which biological materials are prominent examples.

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.

The Leiden Political Economy Group (L-PEG) is a multi-disciplinary network of scholars with a research interest in (comparative / global) political economy based at Leiden University. Our members belong to various institutes and faculties across Leiden University, and from other universities across…

Truth is stranger than fiction. In 1997 Juan Maldaceña discovered a remarkable dictionary that translates equation for equation the physics of black holes in string theory into the more conventional physics of quantum mechanics of interacting particles. The remarkable possibility exists that…

Enforcement of group cooperation fails because of discriminatory punishment, according to research by Welmer Molenmaker and colleagues. When group members have different backgrounds, punishment turns into a double-edged sword: no longer used just to prevent group exploitation, but also to break the…

The thesis focuses on synthesis strategies in oligosaccharide campaigns, and the influence of protecting groups.

The Educational Sciences programme group of the Institute of Education and Child Studies at Leiden University provides courses in the field of student education and the learning and development of children in the school context.

The focus of our theoretical research is understanding the behaviour of soft condensed matter, physical matter which is deformed or structurally altered by thermal fluctuations or small stresses.

The programme group Research Methods and Statistics offers support to researchers from a variety of research projects within Education and Child Studies.

The development of space resource activities is happening now. In the absence of a clear framework to govern these activities, there is a need to examine the concepts that are being discussed in order to ensure that they meet existing treaty obligations regarding on-orbit operations and space resource…

We explore the particle physics and quantum world at the time of the big bang.

Interest groups play an important role in democratic society.

Een medewerker van Frontoffice Studentenzaken legt uit waar je vooral rekening mee moet houden als je je wilt aanmelden bij de Universiteit Leiden.

We study the structure, dynamics and physics of complex networks emerging from the intricate interconnectedness of the constituents of large systems.

Industrialised countries extract natural resources in the territories of indigenous peoples, and appropriate the knowledge and culture of these peoples. Leiden anthropologists work to protect the rights of indigenous peoples. Their knowledge and advice enable governments to source sustainable produc…

Most of current public-key cryptography is considered insecure against attacks from sufficiently powerful quantum computers. Post-quantum cryptography studies methods to secure information resistant against such attacks. One proposal is isogeny-based cryptography, which bases its security on computational…

In our teaching, we give all our students the opportunity to learn about sustainability themes and issues, where possible ones that tie in with the content of their degree programme.

For Humans of Psychology, students and staff will be put into the spotlight. At our institute prizes are won, exiting research is conducted, knowledge is harnessed, public meeting are organised and open science is highlighted. Take a look behind the scenes.

Within the bachelor's program of Education and Child Studies, we include the minor Kindermishandeling en Verwaarlozing: een levensloopperspectief and several other courses.

Do you often feel drained after a day at the office? The new SPS Monitor measures how sensitive you are to various stimuli. Psychologist Véronique de Gucht developed the questionnaire. 'I want to demystify high sensitivity.'
