The overarching clinical aim of this thesis was to improve pharmacological pain management by characterizing the pharmacodynamics of analgesics.

This thesis explores Breaking of Ensemble Equivalence (BEE) in random graph models by examining the spectral properties of adjacency matrices. The goal is to identify spectral characteristics that differentiate random graph ensembles, enhancing the understanding of complex network structures and beh…

Second-year MIRD students showcase their thesis research on global issues during the 2025 Thesis Symposium, bridging theory and diplomatic practice.

Elise Darras studeert aan het Leiden University College (LUC) en be besloot een maand lang stage te lopen in Frankrijk bij H2Air.

The 18th-century rediscovery of the three archaic Greek-Doric temples in Paestum in southern Italy turned existing ideas on classical architecture upside down...

During last summer, the Faculty of Law offered an Honours Class about the theme 'Governing Crime and Migration'. Hillary Mellinger, one of the participating international students, tells us about her experiences.

Leiden chemists have proposed a new model for enzymatic reactions, in which the flexibility of the substrate is much more important than previously thought. Their results are paradigm-shifting and could have major implications for drug research and enzyme engineering. Publication in Angewandte Chemi…

A semi-empirical version of the specific reaction parameter approach to density functional theory (SRP-DFT) has been remarkably successful at predicting dissociative chemisorption probability vs. incidence energy curves for reactions on metal surfaces. New quantum Monte Carlo (QMC) calculations on the…

In June of this year, LL.M student Matthijs de Meer visited the East African Court of Justice for an internship.

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”.

This dissertation focused on computational methods based on first principles calculations using the Density Functional Theory (DFT) framework. Emphasis was laid on affordable methods that can provide a tradeoff between computational expense and accuracy.

Artin L-functions associated to continuous representations of the absolute Galois group G_K of a global field K capture a lot of information about G_K as well as arithmetic properties of K.

To an algebraic curve C over the complex numbers one can associate a non-negative integer g, the genus, as a measure of its complexity.

The Encyclopedia of Global Human Migration provides a complete exploration of the prominent themes, events, and theoretical underpinnings of the movements of human populations from prehistory to the present day.

Political scientists Huib Pellikaan and Niels van Willigen (Leiden University) use and elaborate on the theoretical insights from game theory in order to understand nuclear security in changing environment. Now that the relations between the US and Russia have deteriorated and smaller nuclear states…

In ‘Dimensions of Free Speech’, Devrim Kabasakal Badamchi (Leiden University Institute of Political Science) offers a new theoretical framework for free speech by critically analysing the major justifications for free speech. Kabasakal Badamchi argues for a justification: namely the double-grounded…

Chapter 1,contains the numerical verification of the Birch and Swinnerton-Dyer conjecture for hundreds of Jacobians of hyperelliptic curves of genus 2, 3, 4 and 5.

This project is situated within the context of an innovation of the biology curriculum in Dutch secondary schools. The main purposes are (1) to clarify the relation between teachers’ practical knowledge and the decisions they make when planning and implementing their lessons and (2) to develop a professional…

In his dissertation Gabriel Paiuk explores the variable ways in which what is heard is formed. To address this, he postulates a novel concept of sound image in a post-anthropocentric context in which both mind and material artefacts are instances across which the image occurs, rather than hosts on which…

Alice Twemlow has been named professor by special appointment in the Wim Crouwel chair in the History, Theory and Sociology of Graphic Design and Visual Culture at the Faculty of Humanities of the University of Amsterdam.
