Complex systems can be characterized as systems in which multiple components interact with each other, often in non-linear ways. The main goal of this research will be to investigate if and how the international tax system can be defined and modelled as a complex system. Approaching the international…

Every year, Leiden University welcomes some 27,000 students from 115 different countries. In educating these students, we are committed to ensuring that the quality of our tuition meets or exceeds the highest-possible standards.

Atherosclerosis (thickening of the artery wall) is the most common cause of heart attacks or strokes, and one of the most common causes of death in the western world. People with this condition have to take medicine all their lives, so a vaccine for atherosclerosis would be a breakthrough.

Mathematical models of software systems enable characterizations, abstractions, simulations, and analysis of complex software during its development.

The correctness of computational systems is of great importance to our society, since it becomes ever more reliant on the benefits of computing.

Making systems biology modelling a central pillar of research in biology

The research of our group is centered around dynamical systems, functional analysis and their interplay.

Promotor: A. Doelman, Co-promotores: P.J.A. van Heijster; A. Zagaris

The division of BioTherapeutics consists of the former divisions Biopharmaceutics and Drug Delivery Technology.

Students in Leiden are entitled to good teaching and good supervision. For their part, there are some conditions they have to meet to ensure that they complete their studies within the time allotted.

According to the amyloid cascade hypothesis, accumulation of beta-amyloid (Aβ) peptides initiates the pathological cascade in Alzheimer's disease (AD).

MHC class I and MHC class II molecules present peptides to the immune system to drive proper T cell responses. Pharmacological modulation of T-cell responses can offer treatment options for a range of immune-related diseases.

The research of this programme is centered around dynamical systems, functional analysis, and their interplay.

Mycobacterium tuberculosis (Mtb), the pathogen causing tuberculosis (TB), is the leader among all pathogens responsible for the most human deaths today and it is considered as one of the top 10 causes of death worldwide. There is an increasing occurrence of multidrug-resistant and even totally drug-resistant…

Projects within the theme ‘Computational Biology’ aim to employ mathematical or computational dynamical modelling approaches to discover novel concepts that are important for drug development.

The outbreaks of AIDS and COVID-19 showed clearly how infectious viruses can influence people’s lives. Investigating the changes in the host metabolism may provide a paradigm shift to consider immune-metabolic interactions as therapeutic targets.

The Translational Immuno-Pharmacology group works on translating the efficacy of anti-infective therapy from preclinical (e.g. in vivo) to clinical, and is led by Rob van Wijk. Infectious diseases, such as tuberculosis, are in constant need of new therapies that work better, faster, and with less risk…

Atherosclerosis is a chronic inflammatory disease affecting millions of people world-wide.

The master's specialisation Bioinformatics at Leiden University focuses on research, development and application of computational tools and approaches for expanding the use of biological, medical, behavioral and health data.

Promotor: Arjen Doelman, Co-promotor: Vivi Rottschäfer

The two-years master’s specialisation System Biomedicine and Pharmacology at Leiden university focuses on predicting drug response with computational modelling, developing individualised therapies, and developing innovative analytical tools for personalised health strategies.

This thesis provides explicit expressions for the density functions of absolutely continuous invariant measures for general families of interval maps, that include random maps and infinite measure transformations, not necessarily number systems.

Interaction between Legal Systems acknowledges that law-making and law enforcement are increasingly taking place on various levels: in a global context, in EU context, on a national level and in a private law framework. These levels influence each other, sometimes directly, on the basis of a hierarchical…

How do balanced lethal systems originate and persist in nature?

In condensed matter systems electron-electron interactions, negligible in everyday metals, can dramatically alter the electronic behavior of the system. Examples of such altered behavior include high-temperature superconductivity and modulation of the electron density.

Plant biologist Pingtao Ding, assistant professor at the Institute of Biology Leiden (IBL), has received a 2.4 million European grant from the European Research Council (ERC). This ERC Starting Grant for promising young researchers allows him to unravel the molecular mechanisms by which plants resist…

Control of infectious diseases poses continuous challenges for human health.

Thermodynamics is one of the founding scientific pillars that has helped us better understand heat engines, biology, ecosystems, and even black holes. While it fundamentally describes large systems by examining the bulk behavior of their constituents, it is anchored in the statistical equivalence of…

The research groups within the biological, soft and complex systems research area study the physics of a broad range of biological and soft materials. This spans both experimental and theoretical research.

Pharmacologist Amanda Foks is one of the ten talented scientists who received a Dekker grant from the Hartstichting. She receives €427,000 to find a way to rejuvenate immune cells to prevent infarcts. Foks was nominated as Discoverer of the Year in 2016.

In this thesis, we have studied the potential of the zebrafish larval model in studying the ECS, as a complementary model to the existing rodent models.

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.

This book explores the boundaries of the category of gender and their theoretical significance within the framework of Canonical Typology.

Grammatical gender is famously the most puzzling of the grammatical categories. We have a solid typology of gender systems, yet exciting and unexpected patterns keep turning up which defy easy classification and straightforward analysis. Some of these question, stretch or threaten to cross the outer…
