Glucocorticoids (GCs) are widely prescribed as anti-inflammatory drugs due to their well-established immunosuppressive effects.

How can historically-informed performers step outside the confines of the work-concept?

What are the critical elements in sonic materialization of fixed media electroacoustic music and how can these parameters be classified? How would interpretation be defined in performing fixed media music? What are the creative and new ways of presenting fixed media music by incorporating all the presentation…

When a physical system possesses symmetries, these are often accompanied by a representation of the symmetry group on a Hilbert space. Group representations on Hilbert spaces have been extensively studied.

On this page the programme and sessions can be found. The programme will be updated regularly.

The research described in this thesis has, using the zebrafish as a model system, shed new light on the intricate relationship between TB and DM2, in particular on the role of leptin, SHP-1 and glucocorticoids.

The Academy of Creative and Performing Arts (ACPA) provides artistic research and education in the arts.

The theoretical explanation of cosmic acceleration is nowadays one of the biggest puzzles in cosmology.

During my PhD research, I studied the photon statistics of light emitted by a microcavity that contains a single quantum dot (QD) on resonance.

Video interview with Subodh Patil, the new assistant professor in Theoretical Cosmology, about the gravitational waves, hidden universes, music, and whether Dutch, Danish and German fit into one brain.

Does gravity work the same when you look at the largest scales in our universe? That’s what Leiden physicist Alessandra Silvestri will study with a 2 million euro ERC Consolidator grant. ‘We assume that it does, but we don’t actually know.’

The probability for dissociation of molecules on metal surfaces, which often controls the rate of industrially important catalytic processes, can depend strongly on how energy is partitioned in the incident molecule. There are many example systems where the addition of vibrational energy promotes reaction…

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

The Theoretical Philosophy programme consists of 60 EC, to be completed in one year.

Astrid van Alem is a lecturer at the Centre for Linguistics.

Catalysis is of extreme relevance in the production of everyday materials and plays a central role in many aspects of our life.

The Theoretical Physics specialisation prepares you for a career in industrial research and performing problem solving tasks. The master degree is an excellent stepping stone for pursuing a PhD degree.

The work in this thesis demonstrates how to obtain an atomic-scale picture of a diverse set of complex surface structures observed using STM, under disparate conditions.

Louk Rademaker is visiting fellow at Leiden University, Lorentz Institute for Theoretical Physics. He studies theoretical quantum matter physics, connecting the material science to fundamental concepts and methods.

During the programme you will develop strong analytical and computational skills.

The dissociative chemisorption of methane on metal surfaces is of fundamental and practical interest, being a rate-limiting step in the steam reforming process. The reaction is best modeled with quantum dynamics calculations, but these are currently not guaranteed to produce accurate results because…

Nonadiabatic energy transfer from the translational motion (T) of a molecule impinging on metal surface to the metal’s electrons may determine whether the molecule can lose enough energy to adsorb or react.

Several techniques are explored for going beyond the born-oppenheimer static surface model for molecule-surface reactions.

The master’s specialisation Cosmology at Leiden University is positioned at the interface between Theoretical Physics and Observational Astronomy. The main elements are theory, data analysis and numerical simulations, with research on the origin of dark matter as one of the highlights.

This thesis is dedicated to the exploration of the primordial dark ages: unknown physics during the earliest stages of the Universe’s expansion that have not yet been directly probed by observations. Cosmic inflation is a burst of exponential expansion of space after the “Big Bang”.

Call for Papers for the Conference to be held on November 29th and 30th at Leiden University and coordinated by Prof. dr. M.A. (Marcel) Cobussen, involving Keynote speakers Salomé Voegelin, Gascia Ouzounian, Holger Schulze, and Jean-Paul Thibaud.

LIACS prof. Grzegorz Rozenberg is one of the world leaders in research on Theoretical Computer Science and Natural Computing. He is often called the guru of Natural Computing.

The master's specialisation Clinical Neuropsychology consists of three main parts: the mandatory and elective courses, a thesis and an internship.

This project incorporates spatiality into the discussion of medieval demography, allowing for a more nuanced view on medieval town populations. It establishes a maximum population count for towns for periods prior to 1400 and provides a means to compare the ranking of towns using size and density instead…

This research revolves around the philosophical and linguistic elements that naturally belong to the process of learning music scores, including complex contemporary repertoire distinguished by physically decoupled notations or physical polyphonic notations.

Plant Sciences' contribution to the Host-Microbe Interactions research theme is to dissect how microorganisms and microbiomes interact with the plant host and the insects on those plants, and how these insights may be harnessed to improve plant growth and health, by steering microbiome composition and…

How can we assist Universitas Indonesia's department of International law to improve their educational and applied research programs on Transnational Law, Asset Recovery and International Investment Arbitration, with an eye on Indonesia’s security and rule of law reform agenda and the needs of the…

Theoretical physicist Stephen Hawking (76) passed away on 14 March at his home in Cambridge, having been a long-term sufferer of the muscular disease ALS. A number of Leiden scientists look back at the life and scientific career of this world-famous physicist. 'He was very approachable and extremely…

Edited by linguists Jenny Audring (Leiden University) and Francesca Masini (University of Bologna), this is a unique handbook with a focus on morphology theories rather than morphological data. It covers a wide array of morphological theories, from traditional twentieth century models to current theoretical…
