My ERC Starting Grant, funded with €1.5 million for 5 years as part of the Horizon 2020 research and innovation program, is focused on building the early warning system WARN-D to reliably forecast depression in young adults before it occurs. Why depression, and why prediction?

When you walk into the Gorlaeus Building, you will notice it immediately; the artwork 'The Cloud' hangs prominently in the hall and cannot be missed. Artist Jos Agasi designed it especially for this location. ‘Intuition, imagination and creativity. Scientists and artists have more in common than they…

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…

SAILS likes to occasionally organise workshops about topics that relate to our programme. On this page you can find more information about previous workshops.

This project will construct an inventory of possible conceptions of the resistance of the world to scientists’ claims and theories.

He’s a fast and animated speaker, which is only logical because Gerard van Westen is driving an express train. His destination? A virtual human, consisting of algorithms that predict what an administered substance will do in the body. The train is already a long way down the line and the pharmaceutical…

Making predictions about emotional problems or the effects of air pollution: Marjolein Fokkema’s algorithms are getting better at this all the time. She is making her algorithms increasingly flexible, so they can predict not just characteristics at one particular moment, but also how skills, for example,…

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.

The research programme Descriptive and Comparative Linguistics brings together LUCL researchers who focus mainly on descriptive and comparative linguistics.

Speakers from various academic backgrounds and in different stages of their careers reflect on diverging ways in which technological and social changes challenge and transform…

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…

Urbanisation is steadily increasing with estimates expecting that 68% of the global population will live in cities by 2050. To accommodate the rural to urban transition, large quantities of land are transformed from natural to urban lands.
