In this project, we will study the genetic and environmental drivers of woodiness and stem lignification at the level of plant‐to‐gene‐to‐molecule.

Over the past century, the world population has grown exponentially, as has our need for energy and raw materials. If we wish to continue to live prosperously in the future, we have to radically restructure our economy and consumption. Scientific research shows us how to do this.

‘Tell me something I don’t know,’ said skating coach Jac Orie to Leiden data scientist Arno Knobbe. And he did. Knobbe and his colleagues now assist athletes in all kinds of ways with the help of data mining.

Through metabolism, biochemical processes give rise to the complexity of life. Acquired and inborn errors in metabolism underlie many diseases occurring in man. The challenge for present day medical biochemistry is to find, and integrate, pieces of information at molecular, cell and organismal level…

The goal of hit and lead optimization is to optimize suitable chemical starting points that can modulate a drug target. The methods and technologies used are similar to those in Hit Discovery, but once the compound has shown activity in an animal model, it moves from 'hit' to 'lead.'

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.

In his dissertation Gabriel Paiuk explores the variable ways in which what is heard is formed. To address this, he postulates a novel concept of sound image in a post-anthropocentric context in which both mind and material artefacts are instances across which the image occurs, rather than hosts on which…

The majority of scientists, from archaeologists through to zoologists, collect huge volumes of data. Their massive databases contain large amounts of information which is difficult for humans to filter. With a solid grounding in statistics, we can develop algorithms for analysing and identifying patterns…

AI-tools are introduced within our infrastructure, work, communication, interpersonal relations, economy, democracy, health, science etcetera, to overcome limitations and/or increase efficiency, speed, reliability, convenience. Given the impacts across society, AI requires broad action and reflection…

We depend on nature for so many things: from clean water, wood and food to carbon absorption, water purification and coastal protection, as well as for relaxation, inspiration and identity. Nevertheless, our modern world putting increasing pressure on these ecosystem services. Leiden researchers investigate…

Leiden University's interdisciplinary research programme SAILS funds young interdisciplinary scientists working at the intersection of AI and other fields. How do these researchers experience the work?

The main research theme in the group of Dennis Hetterscheid is to understand and mimic bioinorganic multi-electron processes that are relevant to our future energy infrastructure. Reduction of protons generates hydrogen that can be used as a chemical fuel. Alternatively to gaseous hydrogen, the reduction…

Over the past century, the world population has grown exponentially, as has our need for energy and raw materials. If we wish to continue to live prosperously in the future, we have to radically restructure our economy and consumption. Scientific research shows us how to do this.

Since the late 1990s Leiden University has been located in two cities: Leiden and The Hague. Leiden is where the University was founded and still forms its heart, with six of the seven faculties being housed there. The faculty of Governance and Global Affairs is located in The Hague and most of the…

Leiden has much to celebrate: first, 450 years of the Relief of Leiden and then 450 years of Leiden University. And that is no coincidence.

Leiden researchers Reinout Vriesendorp, Jessie Pool, and Harold Koster from the Department Corporate Law and Jan Adriaanse and Marc Broekema from the Department Business Studies are about to start a collaboration with Groningen University. The WODC (the knowledge centre in the field of the Dutch Ministry…

Lecture

Most people talk about truck drivers rather than to them. That’s an error of judgement, says PhD candidate Anke van der Hoeven, who explains why we should be making their lives easier. ‘People just don’t realise it, but they’re an invisible group that keeps the European economy running.’

Medicines can work even if they have no active ingredient. The first international scientific conference on placebos will take place in Leiden from 2 to 4 April. Placebo researcher Andrea Evers, who is also chairing the conference, answers some pressing questions.
