Conferences, Workshops and Lectures showcasing research and tools in Digital Humanities.

You can find the Digital Lab on the ground floor of the Huizinga building. The Digital Lab is part of a collection of labs designed for staff and students who require a place to work, experiment, and find support for their digital research.

There are eight institutes at the Faculty of Mathematics and Natural Sciences:

Have you experienced or witnessed unacceptable or transgressive behaviour? The University has a page that gives information about what you can do yourself and which ‘helplines’ can assist you in this situation.

In this thesis, we show that we can use Shimura’s CM theory to explicitly compute the Hilbert class field of any primitive quartic CM field.

A neural network mimics how our brain works. Evolutionary algorithms use the principle of natural selection to solve complex problems. This kind of 'natural computing' is being used to improve the diagnosis of Parkinson's disease or the production of steel.

A computer can look at, and learn from, many more images than a human specialist. AI systems are rapidly becoming indispensable for medical and biological applications. But they still have to learn how to explain their decisions.

The master’s specialisation ICT in Business at Leiden University is designed to provide a flexible framework for graduate study in information management and is of particular interest to students wishing to pursue a (international) business career involving both ICT and Management.

The two-years master's programme ICT in Business and the Public Sector (last intake in February 2025) at Leiden University provides students with a deeper understanding on our thinking on physical, geographical and industry boundaries, on distance, speed and communication. The programme offers two specialisations:…

Developing computational algorithms for structural biology -A high resolution, three dimensional view of a molecule provides detailed information that help elucidate its function: by knowing the exact arrangement of atoms in a molecule, we can understand disease, develop drugs to combat them and improve…

How can you use robots and automatic recognition of microscopic images to test the effect of drugs exceptionally quickly?

Leiden University has student exchange and scholarships agreements with various Chinese Universities, varying from long-term exchange programmes to two-week Summer Courses.

The thesis addresses the long-term dynamical evolution of hierarchical multiple systems.

Peter Flach is Professor of Artificial Intelligence at the University of Bristol. An internationally leading scholar in the evaluation and improvement of machine learning models using ROC analysis and calibration, he has also published on mining highly structured data, on knowledge-driven and explainable…

With the advent of multicore processors and data centers, computer hardware has become increasingly parallel, allowing one to run multiple pieces of software at the same time on different machines. Coordination of these pieces is best expressed in a coordination language as an explicit interaction protocol…

From nanoparticles to colliding ice planets and from biological origami to new x-ray scanner techniques: this year again, our scientists have made wonderful discoveries. From the largest numbers to the smallest molecules and from the oldest galaxies up to the latest algorithms, take a look at each institute's…

How does task context affect children’s word productions?

Proceedings of the XVII UISPP World Congress (1–7 September, Burgos, Spain). Volume 7/Sessions A4b and A12

Multi-objective evolutionary computation aims to find high quality (Pareto optimal) solutions that represent the trade-off between multiple objectives.

The master's specialisation Applied Mathematics at Leiden University focuses on both computational and fundamental aspects of analysis and probability. It’s also an ideal basis for a PhD degree. Applied Mathematics is an excellent choice if you have the aspiration to pursue a PhD degree

The two-year Master in Statistics & Data Science consists of 120 European Credit Transfer System (EC) points. It consists of a core set of mandatory courses, electives and a Master's Thesis Project.

You’ve been accepted! Leiden University looks forward to welcoming you as a new student. Your next step is to prepare for your studies. Below you can find some tips to help you get a head start as you embark on your studies at Leiden University.

A master's degree in Psychology at Leiden University combines theoretical knowledge with academic and professional skills, making you an attractive candidate for many employers.

The curriculum of this bachelor’s programme gives you an understanding of artificial intelligence and data science with a solid basis in computer science. Both artificial intelligence and data science are broad disciplines that require essential and foundational underpinnings.

Optimality in plant properties and processing.

The CCLS Logo Competition is now closed. We have a winner!

The LLRC has collaborated on developing the communicative tasks for the Leiden Learner Corpus (LLC).

Can we tailor catalysts at the atomic scale by means of high-school chemistry and geometry rules?

The objective of this project is to fundamentally improve our understanding of the ways in which science progresses. Empirical studies have used bibliographic metadata to provide relevant insights, but these studies have failed to tell us how science progresses. Supported by computational advances and…

The Leiden Institute for Brain and Cognition is a network that stimulates interdisciplinary exchange of knowledge and expertise on topics related to brain and cognition and focuses on science valorisation and outreach. Its research members come from a broad and diverse spectrum of specialized academic…

Premature babies almost always require treatment with medication. Doctors usually determine the dosages based on data from children who were not born prematurely, while preterm infants often develop differently. Medication researcher Aline Engbers investigated three commonly used drugs, focusing on…

If an algorithm has to learn to understand language, simply having a lot of data doesn’t help much. Like us, a computer has to learn the language in interaction with others. Tessa Verhoef is fascinated by how this interaction works.

In the future, physicians may be able to identify dementia much earlier than they can today because a computer algorithm will be able to predict from brain scans how our memory is going to develop.

The Data-Driven Drug Discovery Network (D4N) is an initiative by researchers from Leiden University and collaborators to join efforts in applying and developing novel techniques from data science to drug discovery and related topics from bioinformatics.

What is the Electronics Department?

Our project focuses on the analysis of decision-making processes in the European Union (EU) and explores how approaches and tools to understand decision-making found in both the Natural and the Social Sciences can be linked, knowledge between these traditions exchanged and synergies utilized. To explore…
