Over several decades, a variety of computational methods for drug discovery have been proposed and applied in practice. With the accumulation of data and the development of machine learning methods, computational drug design methods have gradually shifted to a new paradigm, i.e. deep learning methods…

Constant Hijzen and Simon Willmetts have released Spies, Culture, and Society, a collection of essays, published by Georgetown University Press, exploring the relationship between intelligence agencies and the societies and cultures they inhabit.

You can do a degree in Artificial Intelligence at Leiden University, but its role is also increasing in other degree programmes.

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…

On the basis of the characteristic aspects of a picture, certain computers can tell us what the picture is showing. They can learn this in the same way that young children are able to learn to recognize images. Further improving these techniques opens the way to a whole range of new applications. Biology…

The Faculty of Archaeology

The chaotic years after the Civil War are often seen as a time of uniquely American idealism—a revolutionary attempt to rebuild the nation that paved the way for the civil rights movement of the twentieth century. But Adam Fairclough rejects this prevailing view, challenging prominent historians such…

Science begets technology but technology also begets science. Anne Urai from the Leiden Institute of Psychology is part of an international team team that rolls out a new, user-friendly, plug-and-play AI tool they hope will become an engine of discovery by quantifying the growing volume of recorded…

The AI Humanities Lab in Huizinga 0.09c is an innovative space where researchers explore the intersection of Artificial Intelligence and the Humanities. 

Agricultural foods naturally vary in their detailed internal structure. To facilitate early detection of health hazards due to contamination or disease, predict maturity and minimize wastage, it is critical to take into account the internal characteristics of each individual product, as these enable…

This dissertation investigates how the efficiency of Computed Tomography (CT) can be improved for dynamic scientific and industrial applications.

In this course, you will gain a deep insight into the rules that govern armed conflict, and aim to mitigate human suffering on the battlefield. You will explore the why and how of International Humanitarian Law, followed by the different types of conflict.

FAIR-ASSESS is supported by a scientific committee comprising internal members connected to Leiden University and external members from outside the university with expertise in the field.

Plant Sciences' contribution to the Bioactive Molecules research theme is to identify new plant bioactive molecules, and unravel their mechanisms of action in plant development or health, and the regulatory networks and (bio)synthetic pathways required for their production.

In this thesis, we examine various systems through the lens of several numerical methods.

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

Optical projection tomography (OPT) is a tomographic 3D imaging technique used for specimens in the millimetre scale.

This master’s programme combines Physics with Data Science. You will learn how physics has its own tricks to deal with big data and how techniques from machine learning and deep learning can be applied to classical and quantum data. The first focus of attention is on classical data, including data mining,…

How is it possible that people kill each other? And above all: how is it possible that people who are able to peacefully live with each other at one moment, can kill each other at another one?

The overarching aim of the ICLON research programme is to improve the quality of teaching-learning situations through a deep theoretical understanding of teaching and teacher learning.

This project unites these two perspectives by taking a deep dive into the microstructure of historic Dutch bones. We will study human skeletal remains curated at the Faculty of Archaeology by micro-CT scanning them at LUMC facilities. With detailed micro-CT scans, we can examine bone quality in the…

The master’s programme in Dutch linguistics at Leiden University provides you with a deep understanding of the Dutch language and the multifaceted research into the structure and use of the Dutch language. During the programme you will not only gain in-depth knowledge of Dutch linguistics, but also…

A global synthesis of the extent, diversity and patterns in off-site fire use by historically documented and current hunter-gatherers with the remit of this study in the deeper past.

What are the key technical, social, regulatory, economic, and ethical considerations for scaling up ocean-based Carbon Dioxide Removal (CDR) approaches, and what integrated assessment frameworks and governance structures are needed to facilitate their implementation at scale?

LUCDH facilitates workshops that promote the acquisition of skills and knowledge in employing digital tools. Workshops are held in person, and rarely hybrid.

The master’s specialisation Algebra, Geometry and Number Theory at Leiden University is aimed at students who wish to acquire a profound knowledge of one of the areas within pure mathematics. There is a strong theme dealing with algebra and number theory as well as a strong theme dealing with topology…

LUCIS is an interfaculty knowledge centre offering a multidisciplinary and comparative view on Islam and Muslim societies.

This thesis surveys the intersection of computed tomography (CT) and machine learning (ML), treating CT as an ill-posed inverse problem shaped by object properties, imaging physics, and data limitations.

In 'The Spirit of Matter', Peter Pels explores the significance of emotionally evocative objects, challenging the denial of their existence in modern 'mind over matter' ideology.

In this thesis we study products of linear error correcting codes.

With the rising tide of scholarly and societal interest in the history and legacy of colonialism and slavery, this collection offers a much-needed diachronic analysis of the cultural representations of the lives and afterlives of those subjected to slavery and indenture. It focuses on the history of…
