CitiObs will consolidate and apply tools and practice-based knowledge for co-creating data, knowledge and local action regarding the environmental impacts of climate change and human activity in the urban context via Citizen Observatories.

Efficiently responding to others’ emotions has great survival value, especially for social species, such as primates, who establish close, long-term bonds with group members. The closest living relatives to humans are the chimpanzee and the bonobo. Studying these species, and comparing them on the exact…

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…

The research group Organizational & Entrepreneurial Behavior investigates the behavior of individuals and groups who start, work in, or lead organizations, in order to inform organizational practice. By focusing on the behavior of (groups of) employees, entrepreneurs and leaders, the main levels of…

The Human Origins group at Leiden University studies the archaeology of hunter-gatherers, from the earliest stone tools in East Africa, more than three million years old, to the origin of sedentary societies towards the end of the last ice age.

The 2012 crisis in Mali, where the state collapsed and terrorist groups took over the north, came as a surprise to many. Mali had been considered a poster-child for democracy and was judged as considerably more stable than its neighbors by leading quantitative indices of state fragility. This article…

This project investigates diversifying and democratizing heritage through practices of “home-making”. We propose to research ‘home-making’ as a non-binary practice of combining memories of roots and routes, dwelling in the present, and desires for the future.

A substance flow analysis, covering about 99 % of the flows of chlorinated substances in the Netherlands.

How can we connect quantum technology and society for an open debate on its future implications and applications?

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…
