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…

What is the effectiveness of (booklet or online) self-help programmes for people with somatic stressors and depressive symptoms? What works best for whom? How to improve motivation and adherence?

Tom Buitelaar assesses how 'agency' is addressed in peacekeeping studies and identifies gaps.

Practice and science show that secure residential youth care in the Netherlands should no longer be used as a catch-all solution. This is the conclusion of several professionals including Professor of Child Law Mariëlle Bruning in Dutch newspaper NRC.

An international team of astronomers, including Leiden PhD student Elia Pizzati, has observed several ancient quasars that, surprisingly, appear to be floating alone in the early universe (less than a billion years after the Big Bang). Until now, astronomers, based on models, assumed that quasars are…

Researchers at Leiden Observatory study the fundamental physics that creates structure in the Universe. These processes collect matter into galaxies and gas into stars. With the use of powerful telescopes and advanced calculations and computer simulations, Leiden astronomers seek to understand the origin,…

In 2013-2014, CML published over 100 papers, contributed to various international sustainability debates, renovated our building and educated thousands of students from all over the world through our MOOC. These accomplishments and many more are highlighted in this booklet, CML wish you a pleasant…

The Dutch PVV party has proposed a legislative amendment that would make helping illegal immigrants a criminal offence. Joanne van der Leun, Professor of Criminology, spoke to NRC newspaper about the criminalisation of illegality: ‘It’s absurd.’

The Summer School in Languages and Linguistics at Leiden University has been a yearly highlight since 2006.

Smart algorithms and powerful processors are just as essential for astronomy as big telescopes. Astronomers at Leiden University therefore constantly operate at the interface between astronomy and data science.

The mission of the Young Academy Leiden centers around three pillars: interdisciplinarity, science and education policy, and outreach. In addition, we have a community & communication workgroup that serves as an umbrella.

The origin and evolution of galaxies are closely linked to many different physical phenomena.

Leiden University has student exchange and scholarships agreements with various Chinese universities, varying from long-term exchange programmes to two-week Summer Courses.

Piercing through the skull with an ice pick, administering electric shocks without an anaesthetic, or applying leeches to the uterus: these may seem like medieval methods of torture, but they are in fact therapies used in medicine. Willem van der Does writes about all of them in his new book. ‘Physicians…

The Leiden astronomer Huib van Langevelde) has been selected as the new director of the Event Horizon Telescope (EHT). The EHT is a collaboration involving about 350 scientists from 18 countries. It combines the ALMA array in Chile with sub-millimeter telescopes around the world and published the first…

In memory of Andrea Evers, Professor of Health Psychology, the Prof. Andrea Evers Fund for Health, Behaviour and Society has been established. With this fund, we aim to honour her deepest wish: to continue research that contributes to health, well-being, and a resilient society.

These are the proposed research projects for LEAPS 2019. Please note that not all projects will go ahead and some may still be added in the near future. Final funding decisions lie with the Faculty sponsors. And please make a note that if you are interested in an ESA project, to check if your state…

The LACDR represents the core of bio-pharmaceutical research at Leiden University, and we interact closely with our partners:

With Brill, LUCIS publishes a peer-reviewed book series, “Leiden Studies in Islam and Society” (LSIS), aimed at an international academic audience.

LACDR is committed to incorporating sustainability into our education and research. By developing environmentally responsible innovations in drug research, promoting the awareness of the importance of sustainability with LACDR staff and students, and implementing sustainable daily practices within our…

Expand your knowledge, gain international experience, and explore global challenges. From summer schools and online courses to virtual exchanges, Leiden University students at all levels (bachelor’s and master’s students, and PhD candidates) can participate in a range of learning opportunities.

The Summer School ‘The European Union, the United Nations and Global Governance’ will focus on a range of topics relevant to interactions between the European Union (EU) and the United Nations (UN) and the EU’s role within current patterns of global governance.

This research delves into a region of space known as the interstellar medium (ISM), which is essentially the area between the stars filled with gas and dust.

The Cide Archaeological Project: Surveying the Turkish Western Black Sea Region

The chaotic years after the Civil War are often seen as a time of uniquely American idealism—a revolutionary attempt to rebuild the nation that paved the way for the civil rights movement of the twentieth century. But Adam Fairclough rejects this prevailing view, challenging prominent historians such…

This thesis explores the theoretical and observational properties of distant massive galaxies that harbour active black holes in their centres and shine brightly at radio wavelengths.

Freshwater and brackish water ecosystems are arguably the most vulnerable ecosystems on earth, due to concentrated human developments in and around them. The Pontocaspian (PC) region located at the border of Europe and Asia contains a variety of brackish water ecosystems and unique inhabitants, known…

This volume considers the military architecture and its impact on local communities in Rome's eastern frontier, which stretched from the north-east shore of the Black Sea to the Red Sea.

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