The focus of our theoretical research is understanding the behaviour of soft condensed matter, physical matter which is deformed or structurally altered by thermal fluctuations or small stresses.

We investigate the physics and design of mechanical metamaterial, intricately sculpted materials with properties set by their architecture.

On the occasion of prof Paul van der Heijden’s stepping down as Rector Magnificus and President of the Executive Board of Leiden University in 2013 the Chair bearing his name on Social Justice was established. It was a “farewell present” of the Leiden University to it’s Rector.

Political scientists Huib Pellikaan and Niels van Willigen (Leiden University) use and elaborate on the theoretical insights from game theory in order to understand nuclear security in changing environment. Now that the relations between the US and Russia have deteriorated and smaller nuclear states…

Political scientists Marijn Nagtzaam (Leiden University) and Patrick van Erkel (University of Antwerp) investigate how electoral rules affect intra party preference voting. Focusing on the effect of two specific rules—the option to cast a list vote and on a single versus multiple preference vote—and…

Researchers using remote sensing technologies have characterized pre-Columbian regularly-shaped earthworks in forests in Central America and the Amazon. In tropical forested mountains in South America, two challenges arise when identifying archaeological sites through remote sensing. Firstly, sites…
