The design for the METIS instrument for the Extremely Large Telescope (ELT) is final. The European Southern Observatory (ESO) has given the green light for production of all parts of the instrument. It is the first ELT instrument, designed and to be built under Dutch leadership, to formally pass the…

The METIS instrument that’s being built for ESO's future Extremely Large Telescope (ELT) in Northern Chile under the leadership of the Dutch Research School for Astronomy (NOVA) has reached an important milestone: the preliminary design has been approved.

Target selectivity is an important aspect of any drug molecule, and certainly a parameter to be optimized. That is not trivial for a number of reasons. First of all hundreds of drug targets (receptors, enzymes, ion channels) exist, and no single lab in the world has assays for all of them.

The Bachelor programme Psychology will admit a limited number of students (Numerus Fixus). Therefore our programme has a selection process. The selection process also gives you the opportunity to discover if Psychology in Leiden is the programme for you.

Exchange selecting courses and projects

Are you interested in participating in a PRE-Class? Then you need to write a motivation letter and complete an application form. Make sure you have permission from your school to participate.

Our selection and placement procedure starts with your application and ends with—hopefully—an invitation to you to enrol as an IRO student. This page tells you all you need to know about the steps to be taken in between.

All applicants for LUC go through a selection process. You enter the selection process by applying in Studielink and submitting a complete application in the Leiden University application portal.

Applications for the 2025–2026 academic year are now closed. Registration for 2026–2027 will be open from 1 September to 30 September 2026. Further information about the application procedure for the coming year can be found below.

Every year, the Young Academy Leiden looks for new members. We alternate between an open vacancy, to which candidates can apply, and nomination by the Faculty Boards and the Executive Board of LUMC.

Less than 1 in 10 drug candidates that enter phase 1 clinical trials actually gets approved for human use.

This thesis describes the importance of being able to control the selectivity of potential drug candidates.

Diacylglycerol lipases (DAGLα and DAGLβ) are responsible for the biosynthesis of the endocannabinoid 2-arachidonoylglycerol (2-AG) in the brain and peripheral tissues. Selective DAGLβ inhibitors have been proposed as a potential treatment for inflammatory diseases with reduced potential for central…

The glycosylation reaction is a pivotal reaction in creating new and complex oligosaccharides.

Sustainable energy from wind and solar is most readily available near the sea.

The effective treatment of tuberculosis (TB) remains a major challenge to global health.

How can the legal and socio-legal research skills of Indonesian jurists be increased in order to promote legal certainty and to strengthen the capacity of the judicial training in the country?

A Selection of the Poems of Sir Constantijn Huygens (1596-1687) was published in July 2015, edited and translated by Adriaan van der Weel and Peter Davidson.

The thesis describes the development, synthesis and biological evaluation of several proteasome inhibitor designs. Mainly, this work focusses on designing proteasome inhibitors that selectively inhibit the immunoproteasome, while leaving the constitutive proteasome mostly, if not completely, untouch…

This thesis describes the design and development of subunit‐selective inhibitors of particular catalytically active subunits of human constitutive proteasomes and immunoproteasomes.

This thesis focused on the exploration of monolayer graphene as a membrane in direct methanol fuel cell (DMFC) applications, with improvements achieved through plasma exposure or damage- free chemical functionalization.

Quantum hardware comes with a different computing paradigm and new ways to tackle applications. Much effort has to be put into understanding how to leverage this technology to give real-world advantages in areas of interest for industries such as combinatorial optimization or machine learning.

Hydrogen peroxide (H2O2) generation via electrochemical oxygen reduction is a sustainable production method for this bulk chemical. However, the selectivity of molecular catalysts for electrochemical H2O2 generation has hardly been investigated in a systematic manner, and it is unknown if their stability…

This dissertation focuses on the overt marking of φ features encoded on perfective active auxiliaries in a group of Southern Italian dialects.

Does becoming a public sector employee change a person’s political beliefs, behaviors and interactions with the state? Do public teachers hold the same values as other professionals and the general Brazilian public?

Both Europe and Latin America face challenges globally and at home. Conflicts over land and resources have been resurgent in recent years.

How do you ensure that a drug has an effect on the right protein – and nothing else? Chemist Anthe Janssen explored various methods for determining the selectivity of potential medicines. He also looked at the substance BIA 10-2474, after a man died in a French clinical trial in 2016. PhD defence on…

EUniWell –the European University for Well-Being in which Leiden University and six other universities collaborate – is among the consortia selected for funding in the ‘European Universities Initiative’. The alliance will receive funding of 5 million euros from the European Commission.

Design and synthesis of two 3-substituted swainsonine derivatives with the aim to improve the potency and selectivity towards Golgi alpha-mannosidase II.

The path to rational drug and dose selection

Nanoparticles can be used as delivery systems for both small molecules and macromolecules such as proteins, peptides or oligonucleotides. This thesis focuses on the use of liposomes, nanometric vesicles formed by a lipid bilayer enclosing an aqueous core. Liposomes are highly versatile delivery syst…

In September 2023 Social Justice Research, a journal from Springer Nature, published a ‘Special Issue on Veteran Reflections’. Eight ‘veterans’ analysed the current status of justice research and suggested new directions and refinements. Herman Steensma, guest member of the section Social, Economic…

Glycoconjugate vaccines are composed of microbial poly- or oligosaccharides covalently linked to a carrier protein.

How do parliamentarians secure their political future? Are their activities in the legislature connected to their place on the candidate list from one election to the next? Political scientists Tom Louwerse and Cynthia van Vonno examine the Dutch case. Their main finding is that speaking in the plenary…

On 14 and 15 March, students can register as candidates for a place in the University Council (UR) or one of the faculty councils. But what do these participation bodies do? UR member Femke van der Meulen takes us through the agenda for the next meeting.

The explosive radiation and diversification of the advanced snakes (superfamily Colubroidea) was associated with changes in all aspects of the shared venom system. Morphological changes included the partitioning of the mixed ancestral glands into two discrete glands devoted for production of venom ormucous…
