This research area is focused on the development and application of novel concepts and models in the emerging area of quantitative systems pharmacology (QSP).

In this thesis, a system pharmacology approach, integrating metabolomics, pharmacology and chemical biology, was applied to understand and modulate the endocannabinoid system across different model systems (cells, zebrafish, mice and humans).

Dynamical systems describe the evolution of objects in a space over time and may be used to model physical phenomena. Due to this, much research is dedicated to understanding the mathematics of dynamical systems.

In modern information systems, a large number of different components are often active simultaneously. This phenomenon - known as concurrency - underlies not only the functioning of computer systems but of any system in which many processes take place at the same time.

Systems are called real-time systems, if the correctness of the system does not only depend on the correctness of the system output but also on whether the output is delivered on time.

Here are some systems and infrastructures that are useful to students.

The aim of the research programme Systems Pharmacology lies in the development of personalised medicine strategies, and development of new systems-based approaches in translational and clinical pharmacology.

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.

Is system thinking through perspectives the solution for biology education to help students see the connections between different topics?

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.

The research within the Division of Cell Systems and Drug Safety, headed by Prof. Bob van de Water, is focused on novel therapeutic modalities and novel concepts in early drug discovery, in order to develop more effective and safer therapeutic strategies. We generate advanced cell and computational…

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.

Adenosine is an endogenous ligand which exerts its action by activating adenosine receptors (ARs), while its circulating levels are controlled via a variety of mechanism and proteins, amongst others the equilibrative nucleoside transporters (ENTs).

Researchers at LIACS are working to devise the computers of tomorrow that will be the backbone of the Cloud and Edge computing paradigms as well as the Internet of Things. In this respect, we are involved in research and development of high performance computing systems, embedded & real-time computing…

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.

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

Making systems biology modelling a central pillar of research in biology

How do balanced lethal systems originate and persist in nature?

There is currently a problem with our ticket registration system. We are looking for a solution.

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

Neurodegenerative diseases, including Parkinson’s disease (PD), are increasing in prevalence due to the aging population. Despite extensive study, these diseases are still not fully understood and the lack of personalised treatment options that can target the cause of the diseases, rather than the symptoms,…

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.

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.

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…

This thesis studies operator-algebraic aspects of subproduct systems, a generalization of product systems of Hilbert spaces.

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.

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

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…

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.

Drug development critically depends on preclinical models that mimic human physiology, yet traditional two-dimensional cultures and animal models often lack predictive power.

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…

We study the physics of a broad range of biological and soft materials

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

At Leiden University we believe it is important that you receive the right kind of support in your choice of study and while you study. This is why we use what we call the ‘Leiden study system’ to help you make a success of your study from start to finish.
