The field of exoplanet research is rapidly advancing through the development of new technology, observing techniques, and post-processing methods.

The high velocity tail of the total velocity distribution of stars provides essential insight into fundamental properties of the Galaxy.

Electron microscopy has become an extremely important techniquein a wide variety of elds.

A dense region of a gaseous and dusty cloud collapses to form a protostar surrounded by a disk and an envelope. This thesis uses both observations and models to study physical and chemical conditions of these protostellar systems which are likely where planets start to form.

Lysosomal acid glucosylceramidase (GBA1) is a lysosomal enzyme that degrades glucolipids with its main substrate being glucosylceramide (GlcCer). Defects in the GBA1 gene lead to glycosphingolipidosis Gaucher disease (GD), in which the hydrolysis of GlcCer is impaired and therefore, it accumulates in…

This research project studies the distribution and impact of medieval malaria in the Netherlands.

Het was 14 oktober weer een drukte van jewelste in de zonovergoten binnenstad van Leiden. Enkele duizenden scholieren en hun ouders bezochten de Open Dag. Bij de informatiemarkt in de Pieterskerk spraken we enkele studiekiezers met elk hun eigen vragen, twijfels en overwegingen.

Stage lopen bij de Politieacademie in Apeldoorn. Dat kan vanaf september 2021 voor het eerst voor derdejaarsstudenten van het bachelorprogramma Security Studies nu de Universiteit Leiden en de Politieacademie de handen ineen hebben geslagen. ‘De stageplaatsen bieden studenten een unieke kans op een…

What is the optimal design of sandy solutions for sustainable climate change adaption, from an ecological, biophysical and societal point of view?

Hoe verwerken we taal en spraak? Hoe voegen we de informatie op verschillende niveaus – intonatie, zinsstructuur, betekenis, toon, woorden, klanken - samen? Hoe staat de informatie op het ene niveau in verband met informatie op een ander niveau?

The research in this dissertation aims to optimise blood donation processes in the framework of the Dutch national blood bank Sanquin. The primary health risk for blood donors is iron deficiency, which is evaluated based on donors' hemoglobin and ferritin levels.

How do you engage society to stop biodiversity loss? How do you create political and social involvement to deal with climate change? And how do you balance the economic needs of industry with the negative effects of pollution? If you find these kinds of questions interesting, then this Pre-University…

Radboud Ancient and Medieval Studies organiseert ook dit jaar een lezingenreeks. Het programma voor het eerste semester is hieronder te vinden.

Prof.dr. Peter Bisschop, hoogleraar Sanskrit en Oude Culturen van Zuid-Azië, heeft een NWO Vrije Competitie subsidie verworven voor zijn onderzoek naar de snelle opkomst van het Shivaïsme in de zesde en zevende eeuw in Zuid- en Zuidoost-Azië. Het onderzoek getiteld 'From Universe of Visnu to Universe…

Ruim 10.000 scholieren en ouders bezochten op 25 februari de Open Dag van Universiteit Leiden. Op verschillende locaties in de stad kregen de studiekiezers informatie over de opleidingen in Leiden en Den Haag. ‘Ik ben benieuwd naar de ervaringen van studenten.’

In this Ph.D. thesis we study the interaction of low energy electrons with thin materials, namely layered materials (graphene, hexagonal boron nitride, molybdenum disulfide) and organic films. At these low energies the quantum mechanical wavelength of the electron wave function is in the order of a…

This multidisciplinary minor provides students with knowledge on how and why humans became the way they are. The minor focuses on the evolution of the species Homo sapiens from other hominin lineages and animal ancestors, and on the various factors shaping this process. Not only is human evolution of…

Kunnen we van quantum-verrassingen quantum toepassingen maken? Kunnen we het leven onderzoeken en opbouwen vanuit de nano-schaal?

Quantum computing is an emerging technology, which holds the potential to simulate complex quantum systems beyond the reach of classical numerical methods.Despite recent formidable advancements in quantum hardware, constructing a quantum computer capable of performing useful calculations remains challenging.In…

In this thesis we study quantum transport phenomena on the nanometer scale, in two classes of materials: topological insulators with induced superconductivity and graphene superlattices.

How were the Russians, under early modern conditions, able to incorporate this distant, undeveloped and, because frequent nomadic attacks, dangerous territory? And what role did the Kolyvan-Voskresensk plants play in this process?

In Mesopotamië (3000 v. Chr. tot 70 n. Chr) zijn de oudste vormen van literatuur en recht gevonden en belangrijke ontdekkingen in de wetenschap en techniek gedaan. Al deze ontwikkelingen zijn op kleitabletten in spijkerschrift vastgelegd. Daarom kan bestudering van spijkerschrift ons ook nu nog veel…
