Operators in the Lexicon opens with an old chestnut: why are there no natural single word lexicalizations for negations of the propositional operator and and the predicate calculus operator all: why neither *nand nor *nall?

The Mathematical Institute is one of the eight institutes of the Faculty of Science. The institute operates as a single unit defined by the activities of its members.

All research at Leiden University is organised into institutes. To do justice to the wide spectrum of research (and consequently teaching) that comes from these, you will find descriptions of all the Leiden institutes on these pages.

The Hazelhoff Centre for Financial Law provides academic teaching and performs research in the field of financial law.

Kidney failure is a serious issue because kidneys cannot regenerate themselves after injury. A possible solution consists of artificially growing healthy kidney tissue. To achieve that, scientists first need to understand kidney development during the earliest stages, in the fetus. Leiden researchers…

Leiden University supports refugee students by improving access to education, removing obstacles to academic success and encouraging contact with fellow students and staff. In doing so, we strive to contribute to an inclusive climate at Leiden University.

Since the start of academic year 2020-2021 LUGO started working on new goals to increase the effect of our work within Leiden University. Below, the goals for the current academic year will be explained. For now, LUGO will continue to work on the accomplishment of the goal called 'Reduction of single…

A high performance computer or supercomputer owes its massive processing capacity to the fact that it chops a single overarching task into a whole series of smaller tasks. It simultaneously tackles each of those smaller problems.

GitLab is a single application for the entire software development lifecycle. We use the Leiden University gitlab services

Leiden Law School offers four different Bachelor’s (LLB) programmes.

Which brain cell does what, when Parkinson's disease arises? It won't be long before this jigsaw is solved piece by piece. Ahmed Mahfouz, computational biologist, combines bio-knowledge from Leiden with algorithms from Delft and is getting closer to finding the key.

The quantum nature of matter and light has grown into a broad and fruitful research field for theorists and experimentalists alike. It combines foundational research with toward applications, the most well known of which is the quantum computer.

Can we determine the 3D structure of a chemotaxis core complex using single-particle reconstructions via cryo-EM?

Three at the same time: a ligation strategy combining tetrazine–norbornene cycloaddition, Staudinger–Bertozzi ligation, and copper(I)-catalyzed click reaction was used to label the three catalytic activities of the proteasome simultaneously in a single experiment. The orthogonality of the three ligation…

Steffen Brünle's group investigates G protein-coupled receptors (GPCRs). These essential membrane proteins are prime targets for therapeutic drug development in disease and cancer treatment.

This minor is developed for third year students and is only accessible for bachelor students who have obtained their ‘propedeuse’, we are sorry to tell you HBO students cannot apply.

The van Exter group has an extensive history of prior research in classical and quantum optics. As former part of the group of Han Woerdman, we have studied topics as diverse as:

How did interests outside the scope of the Dutch chartered trading companies influence the career-paths of Dutch colonial governors?

North, Middle and South America together constitute the single largest area in World Archaeology that is taught as a single focus. It is also the only major world area that saw societies develop from hunter-gatherers to early empires entirely independent from developments in Eurasia & Africa. It is,…

In deep reinforcement learning, searching and learning techniques are two important components. They can be used independently and in combination to deal with different problems in AI, and have achieved impressive results in game playing and robotics. These results have inspired research into artificial…

In June-August 2010 large scale excavations were executed on the cemetery belonging to the monastery, an area now termed the Paardenmarkt, by Hollandia Archeologen in cooperation with Leiden University. During the course of nine weeks, the students from the former minor Human Osteoarchaeology excavated…

The CIGR brings together a diverse range of unique expertise in genome research rooted in biology, chemistry and physics. Members of the CIGR investigate genome folding and genome transactions. An important aspect is direct as well as long term relevance for medicine.

Research question

In this article, Lydie Cabane, Assistant Professor at the Institute of Security and Global Affairs, and Martin Lodge address the question of how to manage banking crises, a question that has gained prominence since the banking crisis of 2007-2009. This article sets out the rationale for regulating for…

How to come to valid risk stratification of alcohol use disorder?

The Catholics were by no means pitiable victims over the two centuries that they had to practise their religion underground, Caroline Lenarduzzi writes in her PhD dissertation. They managed to keep their faith alive from the mid-sixteenth to the mid-eighteenth century. PhD defence 25 October.

The Cambridge Studies in International and Comparative Law is the leading general series for monographs in international law which will celebrate its 70th anniversary next year.

The Hazelhoff Centre for Financial Law team regularly publishes in both Dutch and international academic journals and book series.

Political scientists Marijn Nagtzaam (Leiden University) and Patrick van Erkel (University of Antwerp) investigate how electoral rules affect intra party preference voting. Focusing on the effect of two specific rules—the option to cast a list vote and on a single versus multiple preference vote—and…

The ambition of the Medical Systems Biophysics and Bioengineering group led by Alireza Mashaghi is to develop and use physics and engineering concepts and tools for pathophysiology, diagnostics and therapy.

Lots of efforts are being made to promote open science practices in scholarly publishing. However, information on the openness of scholarly journals is highly fragmented. There are various data sources that provide information on specific aspects of openness, but there is hardly any integration of these…

Multi-Angle Dynamic Light Scattering (MADLS) is a technique that is used to determine properties of particles in suspension. The measurements give the hydrodynamic size distribution of individual particles as well as particle clusters, and assists in the interpretation of the stability of the particles…

Product packaging is essential. It prolongs shelf-live and highly influences purchasing decisions. However, it’s also a big source of waste, especially single-use plastic. Have you ever felt conflicted choosing a product due to the material it’s packaged in? Or opted for a different product due to its…

Our group operates at the cross-roads of different disciplines: molecular and cellular microbiology, biochemistry, structural biology and biophysics. The group harbors expertise in a multitude of molecular and cellular approaches including:

An environmental and palaeo-economic reconstruction.

In this dissertation, we work towards an experiment in which we aim to bring a micrometer sized magnet at the tip of a soft cantilever into a superposition.

The research described in this Thesis was aimed at designing and synthesizing nature-inspired compounds as part of TB vaccine discovery.

This thesis describes the importance of being able to control the selectivity of potential drug candidates.

The aim of this thesis is to explore the use of Bioorthogonal Antigens to study the cross-presentation pathway.
