Given the accelerating appearance of antimicrobial resistance, there is an urgent need for more fundamental research into novel antibiotic strategies. The work in this thesis helps to address this global problem by developing new antibiotic compounds, inspired by the antibacterial mechanisms of the…

BlaC is the β-lactamase of Mycobacterium tuberculosis. We show that it can recover from inhibition by clavulanic acid and that phosphate helps it do so.

A structural investigation of coiled coil peptides used as membrane fusogens, mimicing naturally occuring coiled-coil fusion proteins. Synthetic modifications have been made to alter lipid attachment, secondary structure and to insert photoactive azobenzene moieties for active control over coiled coil…

Clinical development of drugs for central nervous system (CNS) disorders has been particularly challenging and still suffers from high attrition rates.

This thesis presents pioneering work on the panchromatic emission of some of the most luminous galaxies in the early Universe: star forming galaxies and active galactic nuclei.

Promovendus Ludwig Hoffmann gaat dankzij een Rubiconbeurs die hij op 11 april won twee jaar naar Harvard University in de VS. Met behulp van theoretische modellen bestudeert hij biologische materialen, bijvoorbeeld tijdens de morfogenese. Dit is het proces waardoor weefsels of organismen hun vorm ontwikkelen.…

Waar komen International Studies alumni terecht na hun afstuderen? Maak kennis met Guido, Paulien en Lennart. Zij deden alle drie de bachelor International Studies aan de Universiteit Leiden in Den Haag en zijn na hun studie in heel verschillende sectoren terechtgekomen.

One of the key quests in astronomy is to study the growth and evolution of galaxies across cosmic time. Radio observations provide a powerful means of studying the formation of stars and subsequent buildup of distant galaxies, in a way that is unbiased by the presence of dust.

Programma directeur van het bachelorprogramma Security Studies Daan Weggemans trapte vanmiddag het eerste webinar voor studiekiezers af. In Kaltura Live had hij een internationaal publiek van zo’n 60 geïnteresseerden.

Carbohydrates, or sugars, are the most diverse and most abundant biomolecules known. However, the isolation of carbohydrate samples in sufficient amounts and purity is often impractical or even impossible, so the chemical synthesis of glycosides becomes relevant. The glycosylation reaction, in which…

The adsorption of D2 and CO2 on catalyst surfaces is studied using a molecular beam in ultra-high vacuum.

In this thesis, two potential therapeutic targets for diabetic nephropathy were dentified and investigated. First, we show that glomerular clusterin is upregulated in diabetic nephropathy and demonstrated that recombinant clusterin protein can protect the podocytes against oxidative stress in vitro.…

De Nederlandse krijgsmacht is de afgelopen jaren op vele fronten veranderd. Letterlijk en figuurlijk. Deze uitgave brengt de laatste kennis en inzichten over het functioneren van dit belangrijke instituut bijeen. Een handboek voor praktijk, wetenschap en onderwijs.

Op vrijdag 29 augustus 2025 ontvingen 370 studenten hun bachelordiploma International Studies. De diploma's werden uitgereikt in de historische ambiance van de Pieterskerk in Leiden. Familieleden, vrienden en medewerkers waren toegestroomd om deze heuglijke gebeurtenis met de afgestudeerden te vieren…

Op vrijdag 11 december 2020 vond het eindejaarsseminar van Empirical Legal Studies plaats, uiteraard geheel coronaproof online. Via dit seminar konden collega’s en andere geïnteresseerden op een laagdrempelige manier meer te weten komen over het toepassen van empirische onderzoeksmethoden in de rec…

Ana Oleart kwam van Barcelona naar Den Haag voor haar bachelor International Studies. Na maar liefst twee masters aan de Universiteit Leiden werkt ze nu op de HR-afdeling van een grote hotelketen.

On Monday 26 August, students were warmly welcomed at the Wijnhaven location with a blue carpet and live music. Accompanied by their friends and family, they gathered to receive their BSc Security Studies diploma.

‘Religie is overal’ – dat is de eerste zin uit de missie van het nieuwe Leiden University Centre for the Study of Religion (LUCSoR). Na intensieve voorbereiding en in nauwe samenwerking met het Leiden University Institute for Area Studies (LIAS), is LUCSoR vandaag van start gegaan. Dit nieuwe centrum…

Dit onderzoek gaat over de vormen, functies, betekenissen, en sociaal-culturele waarden die in Palenda besloten liggen, met als doel te begrijpen hoe dit concept via metaforen de wereldbeschouwing van de Muna-volk (Mieno Wuna) weerspiegelt en vormgeeft.
