In this thesis, we study systems of electrons in which strong correlations give rise to emergent exotic physics.

Spectroscopic studies on fluorescent single molecules in organic condensed matter does not only provide information about the molecule itself, but also its near environment. By suppression of phonon-induced broadening of spectral lines through cooling to low temperatures, small changes in the spectral…

A key step in the synthesis of oligosaccharides and glycoconjugates is the formation of the glycosidic bond.

In this thesis we study the landscape of gravitational models which modify GR by introducing an additional scalar degree of freedom (d.o.f.) to source Cosmic Acceleration.

By growing in a soil plants change the biotic and abiotic properties of the soil in which they grow.

The research aims to explore the evolutionary adaptability of enzymes and the impact of temperature on protein evolution pathways, using M. tuberculosis β-lactamase BlaC as the object of study. Enzymes inherently embody a delicate balance between activity and stability, and the acquisition of new enzymatic…

How does ICT affect society? Mirjam van Reisen, professor Computing for Society at the Leiden Centre of Data Science, is intrigued by this question. We speak with her about innovation, changes in health care, and mobile human trafficking. ‘Innovation has many benefits, but it can also be very disrup…

Research into our history of colonialism and slavery, heart-to-heart conversations at a Keti Koti table, exhibitions, lectures and podcasts that establish the link between present and past. Staff and students participated in the national Slavery Memorial Year in many different ways. What have we learned…

On 29 October, seven innovative lecturers from different faculties will join the existing ten fellows of the Leiden Teachers' Academy. The current fellows have been engaged for the past year in implementing their innovation projects. How are these progressing?

The challenge of achieving fast quantification in metabolomics is the presence of severe matrix effects during the MS analysis of complex samples.

Leiden University is under fire: it is allegedly doing too little to tackle antisemitism. Rector Hester Bijl responds to this accusation and to a video from 2014 on social media in which extreme remarks are made. ‘We can be short about such comments: they are unacceptable. The university is and always…

Psychologists Fenna Poletiek and Erik de Kwaadsteniet have received a grant from the FNV trade union to research people’s attitude to work if they receive a basic income. How do they plan to find answers?

This thesis contributes to studying primordial cosmology theories and their detectability in future observations.

The rapid expansion of research on human gut microbiome in recent decades has highlighted its role in human metabolism, immune regulation, and behavior.

POPcorner The Hague has become a familiar and trusted space at Leiden University in The Hague. It’s where students meet, find support and work together to build an open and approachable student community.

The first of April was the official start of Phase II of the collaborative “PCAD4Cod”-project on the effect of sound on fish populations. Hans Slabbekoorn, associate professor at the IBL, is the principal investigator and collaborates with three PhD-students, Dr. Erwin Winter, (Wageningen Marine Research),…

Migration and diversity are key factors in one of the most fundamental transformations of society today. Students study this phenomenon in the Leiden-Delft-Erasmus master’s specialisation in Governance of Migration and Diversity.

Although there is considerable evidence that nature in the city is beneficial to both people and animals, we still do not have an overall picture of those benefits. To rectify that, a Leiden PhD candidate and a student – armed with a cargo bike – are using The Hague as a life-size laboratory.

This thesis focuses on developing wafer-scale two-dimensional (2D) materials by combining synthesis, transfer, characterization, and device integration of graphene, hexagonal boron nitride (h-BN), and BN-doped amorphous carbon.

Hospital pharmacies face significant challenges: the demand for sterile drug reconstitutions is increasing, while specialized personnel remain scarce. Automation offers a potential solution, but its practical implementation in hospitals is still unclear.

Scientists at Leiden University (Netherlands), Stuttgart University (Germany) and Ural Federal University (Russia) have successfully put forward a novel, computed, reaction mechanism that was experimentally tested and show that formaldehyde is formed at much earlier stages in the birthplaces of stars…

A group of confidants including a former student of Meijers managed to avert his deportation to a death camp. In her lecture on 27 November, Cleveringa Professor Marjan Schwegman revealed the history of the persecution of the Jewish Professor Eduard Meijers.

LIACS graduate Lieven van Velthoven won yet another award for his Media Technology MSc graduation thesis entitled

Over the coming years, LUCL will be collaborating on the development of Macroscope, a new scientific infrastructure that maps social change at the population level. Professors Gijsbert Rutten, Stephan Raaijmakers and Carole Tiberius tell us more about the project.

Taking a Bachelor’s in Security Studies while starting and running two businesses: student Mohamed Sulaiman never stops. But he wouldn’t have it any other way. PLNT The Hague entrepreneurs’ hub is a source of help and inspiration.

Synthetic microswimmers take an important place within the interdisciplinary field of active soft matter.

Laura Heitman has been awarded a VIDI grant for her innovative drug research. Heitman strives to optimize a drug’s binding kinetics at its target in order to ultimately fight diseases effectively. She even pleads for a paradigm shift in drug discovery.

The Leiden University College (LUC) education team behind The Learning Mindset (TLM) has received 800,000 euro’s during the Dutch Higher Education Award Ceremony 2022. The LUC team was second behind Universteit Twente. The prize was awarded during the annual Comenius Festival of the Comenius Network.…

Metal complexes and 2D materials like graphene were combined to produce structures that can function as sensors.

Cathodic corrosion is a relatively unknown phenomenon that can severely etch metallic electrodes at cathodic (negative) potentials.

Single-molecule spectroscopy has become a powerful method for using organic fluorescent molecules in numerous applications.
