The discovery of new medicines is a tedious and lengthy process. On average, over 10,000 molecules need to be studied for one to become a drug and reach the patient. Part of that process are the very costly clinical trials in humans, and candidate drugs often fail due to side effects or lack of efficacy.…

How can we deal with today’s global challenges in sustainable, peaceful, fair, democratic, and effective ways? How can global events such as geopolitical shifts, ecological changes, technological innovations, and pandemics be better governed? Addressing these complex questions requires innovative, multidisciplinary…

Business Studies spans science, medicine, and business, focusing on areas such as technology management, innovation, entrepreneurship, operations, and decision making.

Because of their large surface area and immunological competence, mucosal tissues are attractive administration and target sites for vaccination.

In meta-analysis, heterogeneity often exists between studies. In such cases, it is essential to investigate the sources of heterogeneity and understand the relationship between effect size and study characteristics (i.e., moderators).

On 1 June 2022, Bruno Braak defended his thesis entitled 'Overcoming ruptures: Zande identity, governance, and tradition during cycles of war and displacement in South Sudan and Uganda (2014-2019).' The doctoral research was supervised by Prof.dr. J.M. Otto, Dr.ir. C.I.M. Jacobs, and Dr. C. Leonardi…

With increasing carbon dioxide levels in the atmosphere and their detrimental effect on the global climate, modern society needs to push for more renewable energy sources. Storing widely accessible and abundant solar energy in chemical bonds in the form of molecular fuel via artificial photosynthesis…

On Thursday 16 November 2017 Thomas Leclerc defended his PhD Dissertation ‘A Corrective Approach to Reduce Aircraft Greenhouse Gas Emissions. Contribution to the Study of Interactions between Legal Orders of International Law’. The Supervisors are Professor P. Mendes de Leon and Professor L. Grard.

Time-series forecasting through modelling sequences of temporally dependent observations has many industrial and scientific applications. While machine learning models have been widely used to create time-series forecasting models, creating efficient and performant time-series forecasting models is…

The Encyclopedia of Global Human Migration provides a complete exploration of the prominent themes, events, and theoretical underpinnings of the movements of human populations from prehistory to the present day.

Streptomyces bacteria are a valuable source of natural products, many of which are used in the clinic or in biotechnology.

Representing Japanese Colonial 'Heritage' in Taiwan

This programme is aimed at students who have a strong interest in programming and computer science, as well as an interest in the cognitive psychology and artificial intelligence.

The present monograph, spanning a wide range of world and local literatures represents a high academic standard of both literary criticism and philological analysis. By demonstrating her expertise as an Africanist conversant with the Arabic canon, Raia reveals how the narrative of Joseph has been re-narrated…

Reasserting America in the 1970s brings together two areas of burgeoning scholarly interest.

Leiden Journal of Pottery Studies 22, 2006

This thesis involves three topics: benchmarking discrete optimization algorithms, empirical analyses of evolutionary computation, and automatic algorithm configuration.

This book is about the workings of networks of the mobile in Africa, a continent usually associated with the ‘global shadows’ of the world.

On the 10th of November, Martin Kroon successfully defended a doctoral thesis. The Leiden University Centre for Linguistics congratulates Martin on this achievement!

Marieke Liem, Professor Social Resilience and Security at Leiden University, and Katharina Krüsselmann, PhD candidate at Leiden University and Manuel Eisner mapped the flow of homicide cases with the help of a systematic review.

Moot Court: An academic skills training course

Even though more than 4000 extra-solar planets are known today, only a small fraction of these has been captured in an image. To better understand the planet formation mechanisms in solar-like environments we started the Young Suns Exoplanet Survey (YSES).

In the search for sustainable energy solutions, the idea of artificial photosynthesis has been proposed as an approach with which to use water and sunlight to produce hydrogen.

This procedure is relevant for contract and external PhD candidates only.

In this overview of the reception of Duchamp, the plurality of possible approaches is examined.

In this opinion article published in World Development, the authors present five research and policy priorities. While it is clear that ‘pluriversal’ designs need to guide the way forward (Kothari et al 2019), defining a set of key pillars can provide direction and purpose across this pluriversality.…

An analysis of people’s access to justice and the working of (legal) institutions in post-conflict, democratic Libya

The Standard Model (SM) of particle physics fails to explain several observed phenomena and is incomplete. In order to resolve this problem, one may extend the SM by adding new particles.

Complex Organic Molecules (COMs) have been detected in objects across different stages of stellar evolution.

On the 9th of April, Manolis Fragkiadakis successfully defended a doctoral thesis. The Leiden University Centre for Linguistics congratulates Manolis on this achievement!

Fieldwork is an essential part of this research and of course this part of the project is also a joint effort by citizen scientists and professional archaeologists. Discover when fieldwork will take place and how you can participate.

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

One of the key discoveries in exoplanet research over the past decade is the abundance of small planets in our Milky Way. Despite their high numbers, our understanding of their atmospheres remains limited, and it is unknown if they possess atmospheres at all.
