The mission in this division, headed by Laura Heitman, is to design and synthesize novel and better ligands for drug targets. Drug discovery is a lengthy but inspiring adventure. It is often an interplay between academic institutes and pharmaceutical industry, in which scientists at university develop…

This article explores how ISIS and the Taliban have fostered support through their parallel legal systems.

When a star gets too close to a supermassive black hole, it is torn apart by strong tidal forces in a tidal disruption event (TDE).

Artificial photosynthesis aims to produce fuels from solar energy using chemical processes. In semi-artificial photosynthesis, a hybrid approach is taken using both chemical and biotechnology approaches. We aim to develop hybrid systems between light-harvesting nanoparticles and redox-enzymes (oxidoreductases)…

During the early modern period, many medieval manuscripts were cut up into strips of parchment which were reused to reinforce the bindings of newly printed books. Until recently, these reused pieces of medieval manuscripts only came to light when the early modern book binding was damaged and/or subjected…

In this thesis unconventional tools based on fluidic interfaces were developed to study the surface and interfacial chemistry of graphene, to characterize the intrinsic properties of graphene, to disentangle the effects of substrate and of the environmental factors, and to improve handling protocols…

How do humans control their thoughts and actions, and what can high-field brain scanning reveal about the underlying processes?

In this article, Barrie Sander, Assistant Professor of International Law, adopts a narrative theoretical lens to examine how security is constructed, contested, and narrated within three EU regulatory frameworks at the intersection of climate and AI governance - the Critical Raw Materials Act, the AI…

The BENEFIT programme is a public-private ecosystem in a national consortium, aiming to support patients with cardiovascular diseases in their own home setting for a long-term healthy lifestyle.

Crises like climate change and loss of biodiversity threaten our planet. That’s why sustainability is an important topic in research and education across Leiden University. On this website you read how scientists from many disciplines work together in researching sustainability.

Our university labs are bursting with cutting-edge research, but how do you commercialise these inventions and discoveries or translate them into outcomes that benefit society? Professor of biological chemistry Nathaniel Martin started a spin-off company with his team. ‘When it comes to valorisation…

The modification of risk factors and related health behaviors lies at the very core of adequate cardiovascular risk management, yet evidence shows that the majority of people with cardiovascular disease (CVD) fail to achieve a healthy lifestyle in the long term. The main objective of this project is…

How did the Dutch Empire compare with other imperial enterprises? And how was it experienced by the indigenous peoples who became part of this colonial power?

In this paper, Kantorowicz argues that reverse party favoritism exists. He exploits the fact that during the SARS-CoV-2 pandemic crisis, the Polish government was keen to launch postal voting in the presidential elections scheduled for May 2020.

A portrait of the complex historical process of over 500 years of European colonialism in the New World.

Bernard Bernards examines constraints on innovation by focusing on cognitive uncertainty as a personal state that may affect innovative work behavior.

Are you looking for a research project? We have projects available for motivated 6–9-month internship students with particular interest in organic/polymer synthesis, formulation development, gene delivery, protein delivery, and the preliminairy in vitro screening of drug delivery platforms. Students…

On 7 May, Aleksandre Zardiashvili defended the thesis 'Power and dignity: the ends of online behavioral advertising in the European Union'. The doctoral research was supervised by Bart Custers and Simone van der Hof.

Port cities develop at the intersection of international trade and commerce and at the interface between sea and land. What does the future of port cities look like with urbanization, sea level rise, new migrant flows and the disappearance of old industries? This is addressed in the minor (Re)Imagining…

This study focuses on the local level impacts of a highly globalised industry: the international trade in tropical timber.

In design optimization problems, engineers typically handcraft design representations based on personal expertise, which leaves a fingerprint of the user experience in the optimization data. Thus, learning this notion of experience as transferrable design features has potential to improve the performance…

From 20 June to 12 August 2011 a team from the Caribbean Research Group, Faculty of Archaeology, Leiden University and the St. Eustatius Centre for Archaeological Research (SECAR) under the direction of Dr. Grant Gilmore III, Dr. Menno Hoogland, Prof. Corinne Hofman and Dr. Alice Samson carried out…

PathOS aims to contribute to a better understanding and measurement of Open Science impacts and their causal mechanisms. This is pivotal in order to develop effective OS policy in the EU (European Union). It will do so by collecting concrete evidence of OS effects, by studying the pathways of OS practices,…

How to stimulate novel research in science and innovation

Cody Bahir defended his thesis on 1 June 2017.

The CMCB brings together microbial cell biology expertise in Leiden. It aims at optimal resonance between the groups and maximal exploitation of the available infrastructure and to develop innovative cross-boundary technology platforms.

Fourteen promising researchers from Leiden University have been given the opportunity to realise their research plans for the coming years thanks to a Veni grant from the NWO. This year, these subsidies have been granted to studies of the influence of noise on the great tit, the conditions necessary…

In higher education, Open Educational Resources (OER) are available for anyone to use, but they are not widely used.

Galaxy intrinsic alignments induce a major astrophysical contamination to weak gravitational lensing measurements and need to be modelled and mitigated when extracting cosmological information from such measurements.

In the online panel discussion of ESOF 2022 ‘The effect of the online world on adolescents’, together with Amy Orben, Professor Eveline Crone, Sterre van Riel, Professor Anne-Laura van Harmelen and Professor Jan Sleutels, Professor Ton Liefaard shared his research on adolescents and the online world…

Eduard Fosch-Villaronga from eLaw - Center for Law and Digital Technologies, and Hadassah Drukarch, explored the role of intersectionality within (rehabilitation) robot design, testbed, and standards. Being oblivious to these considerations may give way to the development of robots that fall short of…

On 16 September, the Rapenburg canal will be the setting for the Night of Art & Sciences. There will be plenty of things to do, including for international students and staff. We have selected four great acts in advance.

The doctrine of German philosopher Friedrich Nietzsche is complex, contradictory and open to a range of different interpretations.
