Het lijkt misschien ver van je bed, maar wat doe je als je je studie hebt afgerond? Om daar een antwoord op te hebben, bereidt de Universiteit Leiden alle studenten goed voor op de arbeidsmarkt en helpen we je graag op weg aan het begin van je carrière.

Binnen de opleiding Latijns-Amerikastudies richt je je op verschillende vakgebieden. Je verdiept je in taalvaardigheid, moderne geschiedenis, literatuur en taalkunde.

Alledaagse taal uit het verleden kennen wij nauwelijks, maar taalkundig onderzoek van een unieke brievencollectie opent perspectieven. Buitgemaakte brieven van mannen, vrouwen en zelfs kinderen stonden centraal in het Leidse Brieven als Buit-project onder leiding van prof. dr. Marijke van der Wal, dat…

The function of TLRs in innate immunity has aroused worldwide attention soon after its discovery. Because of the broad functions of TLR2 in innate immunity, the drive for the development of TLR2-targeted vaccines or therapeutic treatments has accelerated in the last decades.

The Standard Model (SM) of particle physics fails to explain several observed phenomena and is incomplete. In order to resolve this problem, one may extend the SM by adding new particles.

We have conducted a full spectral line survey of the 3-13 micron region of two massive protostars, AFGL 2591 and AFGL 2136, for the first time at high spectral resolution.

In this research I assess the impact of the recently discovered gas reserves south off Cyprus on the escalation of the Cyprus conflict.

Barrier function is the natural role of the skin. The lipid matrix present in the outermost layer of the skin, the stratum corneum is important for this function.

This thesis describes the development and validation of new high-contrast imaging techniques, with the ultimate goal of enabling the next generation of instruments for ELT-class telescopes to directly image Earth-like extra-solar planets orbiting around nearby stars.

The coursework within the Science Communication and Society (SCS) specialisation prepares students for internships and a career in communication about science and health.

Op 16 juni 2020 verdedigde Andrea Varga haar proefschrift 'Establishing State Responsibility in the Absence of Effective Government'. Het promotieonderzoek is begeleid door promotoren prof. dr. N.J. Schrijver en prof. dr. F. Baetens (University of Oslo).

While ecosystems have concrete benefits for human society, these benefits are typically overlooked in decision-making.

In the search for sustainable energy solutions, the idea of artificial photosynthesis has been proposed as an approach with which to use water and sunlight to produce hydrogen.

Chapter 2 describes a post-synthetic methodology to introduce a fluorescent label in highly lipophilic, Pam3Cys based conjugates.

The chemical and structural heterogeneity of toxoid vaccines makes their analysis challenging. However, detailed insights on a molecular level can be obtained by mass spectrometry.

This thesis aims to enhance our understanding of galaxies by testing theoretical models of galaxy formation against observations, particularly in the cases of extreme systems which have been found to have an excess of baryonic mass in their central regions, in the form of either supermassive black holes…

Astronomical observations of cold regions in the universe show a rich inventory of ices. Part of these ices may end up on planets like our own, but in that journey they will be exposed to considerable amounts of radiation.

This thesis describes the synthesis and biochemical evaluation of a variety of cyclophellitol based activity-based probes and inhibitors targeting various endo- and exo-acting retaining glycosidases. In the last two decades a variety of probes and inhibitors for (hemi)cellulose degrading enzymes have…

The overarching clinical aim of this thesis was to improve pharmacological pain management by characterizing the pharmacodynamics of analgesics. This promotion has been awarded the predicate cum laude.

The study of orchid flowers, fruits, and inflorescences is crucial due to the remarkable diversity of orchid species and their unique adaptations to pollinators and seed dispersers. However, our understanding of the evolution and development of these organs within the orchid family remains limited.

The expedition commanded by Nicolas Baudin to Tenerife, Mauritius, Australia, Timor and South Africa in 1800-1804 is fully researched in regard to ornithology.

In the last decade, the redox interconversion between metal thiolate and disulfide compounds has been extensively investigated for copper, but not for other transition metal ions.

The bacterial cell wall is a nearly universal structure that offers protection and gives the cell its shape. However, environmental stressors, such as cell wall-targeting antibiotics and hyperosmotic conditions, can induce bacteria to shift to a wall-deficient state. It is unknown whether the lack of…

Can we provide the Dutch government with an integrative framework, wherein the various policies can be placed and the need for further measures can be identified?

The focus throughout this thesis will be on gathering fundamental studies of the detailed structure and composition of the electrode/electrolyte interface effect on the rate and mechanism of key electrocatalytic reactions.

My PhD thesis investigates the ecological significance of resistance against drought-induced air bubble formation inside the water conduits of plants (embolism), and the plasticity and functional aspects of stem anatomical traits in woody and herbaceous species.

The Copenhagen interpretation of quantum mechanics states that a measurement collapses a wavefunction onto an eigenstate of the corresponding measurement operator.

To improve cancer treatments, personalized medicine approaches have aimed to identify exactly which mutations are driving tumor development in a given patient and specifically target these mutations using precision therapies.

Decentralized plug and play systems for energy production are the future picture of our society. Artificial photosynthetic systems are used for this purpose.

The thesis addresses the long-term dynamical evolution of hierarchical multiple systems.

In this work, we investigate the minute circular dichroism effects of single nanoparticles.To this aim, we apply photothermal imaging with a polarization-modulated heating beam.

A modern ship design process is subject to a wide variety of constraints such as safety constraints, regulations, and physical constraints.

Large carnivores and humans, along with their livestock, have co-existed for thousands of years. However, human population growth and an increase in economic activities are modifying the landscape for large carnivores and their prey.

Dark matter is one of the biggest mysteries of the Universe. Its properties cannot be explained with the known laws of physics and elementary particles.

The development process of any software has become extremely important not just in the IT industry, but in almost every business or domain of research.

The soil ecosystem consists of the largest reservoir of biodiversity on Earth.

As a virtually inexhaustible source, solar energy plays a major role in future global energy scenarios.
