The development of new environmentally sound technologies is seen as a key route towards achieving sustainability.

Thread-like bacteria make cells that no longer have a cell wall under the influence of osmotic stress. A remarkable discovery, since the cell wall serves as a protection barrier for bacteria. It could also help to explain how pathogenic bacteria can hide in our body from our immune system. A team of…

Language learners in higher education increasingly conduct out-of-class self-directed learning facilitated by mobile technology. This project aims to explore how university students use mobile technology for their self-directed language learning and investigate factors that influence their self-directed…

How digital technologies affect the way we conceive of the self and its relation to the world, considered through the lens of media art practices.

Promotor: G.A. van der Marel, Co-promotor: J.D.C. Codée

Explores the relationship between technics and humanity, tracing the emergence of a bio-technical conception of existence in contemporary continental philosophy. Suny Press

The Case of the Painted Plaster

How can the concept of Critical Making be expanded into a general approach that ties the critical methodology of artistic research, and the established concepts of artistic autonomy, together with contemporary creative-technological development?

An overview of awards and prizes granted to our staff and students in 2019, as well as special appointments and royal distinctions.

Practical applications for the reconstruction of the past

While self-driving cars and autonomous weapon systems have received a great deal of attention in media and research, the general requirements of ethical life in today’s digitalizing reality have not been made sufficiently visible and evaluable.

We are aiming to develop novel technologies to allow better sample preparation or coupling of analytical methods to (i) analyse ultra small samples, (ii) to analyse more metabolites in a quantitative manner and/or (iii) increase the sample throughput.

The Leiden University Medical Center (LUMC), the Danstem Institute from the University of Copenhagen and the Murdoch Children’s Research Institute in Melbourne have received 300m euros from the Novo Nordisk foundation. The aim of this new international consortium is to bring stem-cell based therapies…

LiTechAe: Percussive stone tools related to stone masonry techniques seen through experimentation and use-wear analysis.

This project embarks on empirical analysis of popular psycho-physical practices in contemporary Korea.

Kidney failure is a serious issue because kidneys cannot regenerate themselves after injury. A possible solution consists of artificially growing healthy kidney tissue. To achieve that, scientists first need to understand kidney development during the earliest stages, in the fetus. Leiden researchers…

A new mathematical model may explain how body cells get their shapes and what makes them move within a tissue. The model provides fundamental knowledge for applications in tissue engineering, amongst other things. Publication in open-access journal iScience.

Zebrafish-human communication shows that cancer cells lacking a signaling protein are less able to develop aggressive metastatic properties. This discovery has been made by molecular cell biologist Claudia Tulotta. PhD defence 14 June.

The life of a fibroblast is heavy, but PhD student Julia Eckert makes it 19.5 times heavier, using the Large Diameter Centrifuge at the ESTEC space research centre in Noordwijk.

The main aim of this thesis was to unravel the signaling and regulatory networks that drive tumor cell migration during breast cancer metastasis.

This dissertation contains four works during my PhD. Different biomaterials have been designed based on coiled-coil peptides. These biomaterials have a range of applications, inclusing drug delivery, cell sorting to cell-cell fusion.

The Institute Council consists of scientists, support staff and PhD- and MSc-students. They discuss policies, strategies and other institute matters that may concern any person working or studying at Leiden Observatory.

Chemist Roxanne Kieltyka has received an ERC Starting Grant of 2 million euros. In her lab, she creates gels that mimic the instructive material that supports cells in our body. With the grant, she aims to make these gels stiff and tough, and to create a bio-printed miniature heart ventricle.

Viral hemorrhagic fever (VHF) is a group of acute diseases caused by highly infectious viruses including Ebola, Lassa, Dengue viruses. Its high mortality rate poses high risk to public health, however, studies on VHF have been hampered due to the non-availability of proper models and incomplete knowledge…

Understanding the water use of power production is an important step to both a sustainable energy transition and an improved understanding of water conservation measures. However, there are large differences across the literature that currently present barriers to decision making.

The management teams lead the department and consist of a General Manager, an Outreach Manager, an Instrumentation Manager, an ICT/Housing Manager, a HR/Finances Manager and an Education Manager.

An overview of awards and prizes granted to our staff and students in 2020, as well as special appointments at Leiden University and other institutions.

The Education Office Astronomy supports all aspects of the Astronomy bachelor and master education programmes. Its main focus is on education quality assurance, student monitoring, education-related PR, student recruitment, job market orientation and alumni policy.

Biophysicist Rolf Harkes has developed a microscope to optically localize individual molecules in living cells. It improves monitoring of diseases like cancer and Parkinson’s at the cellular level. Defende PhD thesis on t13 January 2016.

Following in the footsteps of Professor Jan Zaanen, visiting fellow Louk Rademaker is exploring quantum effects in so-called strange materials. His research is paving the way for new materials that could be used in emerging technologies.

Despite the value of technology integration for educational equity and quality being emphasized by numerous studies, many gaps exist about how technology integration can be approached in policy plans, implemented in pedagogical practices, and embraced by teachers, students, and parents.

This dissertation aims to explore how university students use mobile technology for their self-directed language learning and investigate factors influencing their self-directed learning with mobile technology.

On September 9th 2009, the study Life Science and Technology (LS&T) celebrates its 10th anniversary. In 1999, a group of enthusiastic pioneers within the Technical University Delft (TUD) and Leiden University (LU) founded a novel study based on the biotechnological expertise of research institutes within…

Prison staff are working under high pressure. The current proposal for cell sharing is the final straw. Associate Professor Esther van Ginneken appeared on Dutch news programme ‘Nieuwsuur’: ‘Serious incidents have occurred, including the murder of a cellmate.’
