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.

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…

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

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.

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.

Three students of Leiden University’s “MSc. ICT in Business” programme, Erwin Marges, Stefan Zhelyazkov and Georgios Valouras, have been awarded with the prize of Galileo Master of the South-Holland region, for their business plan idea “SnowMate Alpine Assistant”.

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…

This thesis is a (biased) journey through very different topics in astrophysics: quasars and new populations of active galactic nuclei, gravitational waves from merging black holes, and protoplanetary discs around young stars.

Prof. dr. Lisa Cheng has been nominated for the Regional Chair at the University of Nantes (France).

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…

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

The Terrorism and Political Violence research group at Leiden University examines the causes of radicalisation, the tactics of extremist groups, and the effectiveness of counter-terrorism policies. We also explore the role of the media and the influence of postcolonial legacies in the Global South,…

COVID-19 poses a significant barrier to intra-regional trade within the EAC, causing interminable hold-ups at the internal borders.

Pintores, arquitectos y exposiciones internacionales –como las de Barcelona y Sevilla– tuvieron un papel crucial en la definición y visualización del carácter idiosincrático de cada región. Este libro pionero compara el proceso de construcción de identidades regionales en España con el de Francia y…

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…
