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

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…

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.

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

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.

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

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.

Palestinian national Abu Zubaydah was captured by the CIA in March 2002 and has remained in detention ever since, without any form of trial. Leiden professor Helen Duffy is doing all she can to secure his release or a fair trial. Her hopes now lie on international pressure and the UN Working Group on…

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.

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…

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.

How do balanced lethal systems originate and persist in nature?

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.

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.

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…

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.

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

Radical books on Islam glorifying armed jihad and humiliating Jews and Christians are available in the Vught prison library.

Marieke Liem wrote a contribution for DJIzien, a magazine published by the Dutch Custodial Institutions Agency (Ministry of Justice and Security), about her meetings with long-term prisoners. ‘For my research on long-term prisoners I made numerous visits to Dutch prisons. During these visits, I came…

Duality, stochastic processes

Organisms often need to adapt more efficiently and devise new strategies for surviving difficult ecological circumstances.

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.

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…

Leiden Law Cast is a podcast made by Leiden Law School, Leiden University, for everyone who wants to learn more about current legal issues.

This interdisciplinary research project explores several adaptive machine learning methods which can give insight into the interaction between human and machine. The ultimate goal is open and natural communication between humans and AI that should result in mutual trust, cooperation and coordination…

Researchers at the Institute of Criminal Law and Criminology - Paul Nieuwbeerta, Anouk Bosma, Esther van Ginneken, Hanneke Palmen and Maria Berghuis - have received 800,000 euro from the Dutch Custodial Institutions Agency (DJI) of the Ministry of Security and Justice to investigate living conditions…

Discovery and development of Central Nervous System (CNS) drugs is hampered by high attrition rates.

This week the Turkish army invaded North East Syria. The Turkish invasion might well have had an unintended side effect: the escapement of thousands of Islamic State terrorists held in captivity. Experts on terrorism and politicians fear a resurrection of the terror group.

Research into research improves the academic system. CWTS studies and evaluates the academic system in various ways. One way is to provide information on the productivity and impact of academics by documenting how many publications they or their universities produce and how often these publications…
