This study aims to make a practical contribution to a new understanding and use of 3D reconstructions, namely as ‘laboratories’ to test hypotheses and visualize, evaluate and discuss alternative interpretations.

An examination of academic organization at the forefront of the biotechnology revolution

The long-held desire - to link structure directly to function and to explain molecular mechanisms based on basic chemical or physical principles - is finally coming closer, satisfying not only our scientific curiosity but also offering new solutions to the many challenges in the field of health, energy…

Due to their central physiological roles in living organisms, retaining beta-glycosidases have been the subject of tremendous research efforts to examine their structure/function relation using numerous biophysical and biochemical approaches.

This thesis aims to demonstrate how the achromatic nature and design flexibility of liquid-crystal optics can be used to improve high-contrast imaging instruments to facilitate detailed exoplanet characterization.

Particles are omnipresent in biopharmaceutical products. In protein-based therapeutics such particles are generally associated with impurities, either derived from the drug product itself (e.g. protein aggregates), or from extrinsic contaminations (e.g. cellulose fibers).

On 19 September 2023 Tabitha Speelman successfully defended a doctoral thesis and graduated.

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…

The master’s specialisation BioTherapeutics at Leiden University is a two-year programme which trains students in research in specific drug delivery techniques. The programme also examines the development of new therapeutic approaches to treat immune-based disorders, such as atherosclerosis, metabolic…

On 29 June, Erwin Dijkstra defended the thesis 'Discrimination and the foundation of justice: hate speech, affirmative action, institutional opinions'. The doctoral research was supervised by Paul Cliteur and Bastiaan Rijpkema.

Commentators and scholars view both social media and cities as sites of fragmentation. Since both urban dwellers and social media users tend to form assortative social ties, so the reasoning goes, identity-based divisions are fortified and polarization is exacerbated in digital and urban spaces.

This book explores how public health concerns and political agendas influenced each other in the US over the past century.

The master’s specialisation Biology and Business Studies at Leiden University bridges science and business development by focusing on areas such as technology management, innovation, entrepeneurship, operations, and decision making.

Science begets technology but technology also begets science. Anne Urai from the Leiden Institute of Psychology is part of an international team team that rolls out a new, user-friendly, plug-and-play AI tool they hope will become an engine of discovery by quantifying the growing volume of recorded…

Crises arising from terrorism, war, violence, cyber threats, and natural disasters dominate world news and make crisis and security a heavily politicised and hotly debated topic at the top of the national and global societal and governance agenda. This master Crisis and Security Management focuses on…

The War, Peace and Justice group unites scholars and practitioners to explore war dynamics, peace promotion, and justice’s role in conflict and global affairs.

Alexander Kros studies supramolecular systems in a biological environment. The unifying theme between the projects in my lab is specific molecular recognition, i.e. the intermolecular interaction between complementary molecules with high affinity and selectivity. Studying, imitating and dissecting processes…

Do e-waste workers display enhanced effects of adverse health effects due to informal e-waste processing in Nigeria? Is there a difference between the health outcomes of the exposed and the control groups? Are there difference in health effects within and between job groups (collectors, dismantlers,…

The research conducted is centred around three themes. Within the different themes a multi-level approach is used, focussing on issues at the level of the health care system, the level of organizations and networks of organizations and at professionals within organisations.

In STAYAHEAD data-intensive approaches are being developed to ”decode the human immunome” with a focus on a global vaccine strategy. They have developed a rapid mass spectrometric test to analyse in real-time large numbers of variants of SARS-CoV-2 and the host immune response, and use these data to…

The goal of hit discovery is to identify suitable chemical starting points to modulate a drug target. A hit can be, a.o., a small molecule, a protein or mRNA. Hit identification is performed via rational design, genome mining, (targeted) library screening, or in silico approaches.

How does the management of Elephant Marsh Fishery in Malawi relate to wider contexts of policies, theories and regions? And how can the current management system be adapted to achieve long-term sustainability of the fishery?

MRFM combines the principles of magnetic resonance and atomic force microscopy.

Should the law and norms applicable to armed conflict include a distinct category covering the transition from armed conflict to peace, jus post bellum, and if so what are its characteristics?

This project employs a systematic experimental approach to examine the interaction of these two hitherto independent lines of research (tone sandhi and focus realization) in six dialects of Chinese, which lie on a continuum between dialects with dense tonal distributions and sparser distributions. In…

The master’s degree programme Education and Child Studies (Research) is an academic, not a vocational programme. It offers research based knowledge about education and child development.

The Film and Photographic Studies programme will equip you with a broad and interdisciplinary knowledge of lens-based media.

The master's specialisation in Visual Ethnography emphasises a strongly hands-on, empirical approach, which requires students to play an active role in mastering the audiovisual toolbox.

Your local city park may be improving your health, according to a new paper led by Leiden environmental scientist Roy Remme. In Proceedings of the National Academy of Sciences Remme and his colleagues describe how access to nature increases people’s physical activity—and therefore overall health—in…
