On 30 November, Florian Theissen defended the thesis 'Sincerely believing in freedom: a reconstruction and comparison of the interpretation of the freedom of religion and belief on the Canadian Supreme Court, the South African Constitutional Court and the European Court of Human Rights'. The doctoral…

In the research programme Drug Discovery & Safety, we are interested in the efficacy and safety of new drugs and novel means to decipher these aspects. Hence, we employ advanced imaging and high-throughput screening techniques next to computational approaches such as chem- and bioinformatics.

In designing our programmes, we continually make the connection between theory and practice, and we guarantee an active and optimal learning process.

Publishing an article as early as during your studies. Master's students of Nanne Timmer and Astrid Weyenberg are doing it. In the new course 'Leiden Graduate Journal Culture and Society' they are creating an academic journal.

Inaugural lecture

De opening of the Academic Year 2023-2024 took place on Monday 4 September 2023 in Pieterskerk church.

The aims of research and teaching within the Educational Sciences programme are to understand in how individuals develop and learn and to optimize education for all individuals.

If you study Pedagogical Sciences in Leiden, you will be involved in the development of young people and children and how parents, teachers and social workers can contribute to this optimally.

The Institute of Education and Child Studies aims to create a challenging academic environment in which students can flourish.

The programme group Research Methods and Statistics develops and teaches the large majority of methodological courses in all phases of the program Education and Child Studies.

The Education Committee of the Bachelor Computer Science and the Bachelor Data Science&Artificial Intelligence is concerned with evaluating all bachelor programs at LIACS: Computer Science, its Computer Science & Economics and Bioinformatics and the Bachelor DS&AI.

All PhD candidates must be admitted to the Graduate School.

The essay For progress has been published to mark the 450th Dies Natalis of Leiden University. In 2025, we are celebrating our 450th anniversary, and the theme of this special year is Ahead of the Times.

A diploma is a valuable document that the University issues only once. If somebody loses his or her diploma, he or she can download a copy in the diploma register.

Dr. Joris Larik, Assistant Professor of Comparative, EU and International Law at LUC The Hague, has co-authored a report entitled 'UN 2.0: Ten Innovations for Global Governance 75 Years beyond San Francisco'.

Computers are capable of making incredibly accurate predictions on the basis of machine learning. In other words, these computers can learn without intervention once they have been pre-programmed by humans. At LIACS, we explore and push the borders of what a revolutionary new generation of algorithms…

In this thesis, the discovery and optimization is described of chemical tools to study the N-acylethanolamine (NAE) biosynthetic pathway.

In this thesis an activity-based probe was discovered that could visualize the activity of PLAATs. With an optimized gel-based ABPP assay in hand, screening of a compound library led to the discovery of alpha-ketoamides as a hit for PLAAT3.

A hot topic in educational sciences is whether and how reading medium (paper vs. screen) affects reading comprehension. Especially in the media – but also in schools – their appears to be a preference for texts presented on paper: Paper texts are thought to induce a more intensive reading strategy,…

There is little evidence of the routes connecting Amerindian communities in the Caribbean prior to and just after 1492. Uncovering possible canoe routes between these communities can help to explain the structure, capabilities, and limitations of the physical links in their social and material networks.…

If a new method has been developed to recognize and treat a (neuro-)psychological disorder or related behavioral factors, it cannot yet be used directly in clinical practice. First, the method should be evaluated, preferably in randomized controlled trials.

Actinobacteria are Gram-positive bacteria that have a complex multicellular life cycle and are well known for their ability to produce a wide range of bioactive natural products (NPs).

Are you interested in the neurocognitive and biological roots of learning, behaviour and emotions in children? If so, the programme in Applied Neuroscience in Human Development might be the specialisation you are looking for.

The master’s specialisation Artificial Intelligence offers future-oriented topics in computer science with a focus on machine learning, optimization algorithms, and decision support techniques.

Tuberculosis (TB) is associated with 1.5 million deaths annually. There is a need exists to optimize both current as well as novel antibiotic combination treatment strategies to improve the effectiveness and safety of treatments against TB.

The Reinforcement Learning lab conducts research into Reinforcement Learning and Intelligent Combinatorial Algorithms.

Assistant professor and dual PhD candidate, Pieter Slaman writes in Binnenlands Bestuur about the fact that the German occupier lengthened the period of mandatory education in The Netherlands.

At the Leiden Curious Minds Centre, our research focuses on the relationship of exploratory behaviour and discovery learning to curiosity and the way children regulate their behaviour and emotions. We want to improve our understanding of how children can and do become more and more the captain of their…

Clearance is the most important pharmacokinetic parameter for drug dose selection. Pharmacokinetic information is typically first available in the adult population, and in general only limited pharmacokinetic data are available in children when drugs enter into the market. It is therefore of the utmost…

This thesis aimed to investigate core cross-linked polymeric micelles (CCPMs) and expand their potential for the delivery of hydrophobic drugs and co-factors.

In order for professionals to keep learning throughout their careers, it is necessary to be able to steer their own learning process

Accurate prediction of the unbound drug concentration-time profile at the CNS target site is crucial for the assessment of the right drug concentration-effect relationship. PBPK models have supported the PK prediction of the CNS target sites and the translation of PK data between species and between…

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.

Research in the natural computing group covers theoretical foundations, the development of new algorithms, and interdisciplinary applications of natural computing methods.

The Master’s specialisation Educational Science offers students cutting-edge insights into how individuals develop and learn and how education can be optimized to include every learner.

This thesis highlights the significant role of surface geometry and oxidation state in determining CO adsorption behavior on copper surfaces.
