The CIGR brings together a diverse range of unique expertise in genome research rooted in biology, chemistry and physics. Members of the CIGR investigate genome folding and genome transactions. An important aspect is direct as well as long term relevance for medicine.

On 28 June 2024, Dr Kristof Gombeer spoke on State jurisdiction and the protection of people at sea at the 81st Biennial Conference of the International Law Association (ILA) in Athens, Greece.

On November 21, theoretical physicist Juan Maldacena gives the Ehrenfest Colloquium. Maldacena is known worldwide as the inventor of AdS/CFT correspondence, which might be key to a theory of quantum gravity. Maldacena is winner of the prestigious Dirac Prize and the Breakthrough Prize in Fundamental…

Industrial sites are built for safety, but are they prepared for security breaches? As concerns grow over threats to national security, these sites are a target. The Securdomino project built a tool to prevent malicious attacks and rethinks how we define security.

Plant biologist Pingtao Ding, assistant professor at the Institute of Biology Leiden (IBL), has received a 2.4 million European grant from the European Research Council (ERC). This ERC Starting Grant for promising young researchers allows him to unravel the molecular mechanisms by which plants resist…

Gianclaudio Malgieri, Associate Professor at eLaw Leiden, was invited as a speaker at the Annual Conference of the European Academy of Law (ERA), on 21 March in Brussels.

Research at the THEOR group is comprised of the following research themes:

Computers are becoming ever more powerful and are taking on more complex tasks. The Leiden Institute of Advanced Computer Science (LIACS) contributes to revolutionary scientific research and applies the latest inventions in the field, offering answers to today’s questions of society.

Research at the Leiden Institute of Physics (LION) is foundational and curiosity driven. All our scientists share a desire to increase the knowledge of the world around us, in an open atmosphere of inquiry from which innovative ideas emerge that provide applications and value for society.

The effectiveness of the skin barrier underlies the outer layer of the skin: the stratum corneum (SC). However, in several skin diseases this barrier is impaired. In two inflammatory skin diseases, atopic eczema and Netherton syndrome, an increased level of monounsaturated fatty acids (MUFAs) has been…

CWTS is involved in a number of international partnerships and initiatives.

Metals surfaces form a group of effective catalysts for the reaction of small molecules such as hydrogen (H2).

Children have the right to play and relax. Games, social media and video platforms are attractive new ways to do that. However, hardly any online games are designed specifically for children, nor do they factor in children's rights.

Vibrating carbon monoxide molecules adsorbed at the surface of a salt crystal stop moving after a few milliseconds. Scientists now discovered this is dominantly due to the emission of electromagnetic waves. The role of the chemical bond at the surface thereby appears to be less important than previously…
