Situated on the west coast of modern Turkey, the site of Ephesus is one of the largest excavations in Turkey and one of the most visited tourist attractions. Only one tenth of the city has been exposed until now although the Austrian Archaeological Institute in Vienna (ÖAI) has been excavating here…

Many important topics in computer science, such as the correctness of software, the efficiency of algorithms and the modeling of complicated systems, depend on sound theoretical underpinnings. In the Theory group, we study these fundamental building blocks and develop verification methods to prove system…

Archiving Medieval and Post-Medieval Archaeological Fieldwork Data from the Eastern Mediterranean (600-2000)

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 this thesis we use state-of-the-art observations and simulations to provide the best constraints to date on the HVS ejection rate and constraints on the stellar content and dynamics at the GC, including the progenitor binary populations and their star formation history.

Leiden University provides ambitious students with the most recent and innovative areas of knowledge, and offers them the freedom to develop their own area of expertise.

There is greater variety in the size of men’s brains than of women’s. This could help explain why some psychiatric disorders such as ADHD and autism are more prevalent in boys. Leiden brain researcher Lara Wierenga has published an article about this in the international journal Cerebral Cortex.

Higher temperatures are resulting in changes to vegetation and soil in mountain areas throughout the world. An international research team including Leiden ecologist Ellen Cieraad published an article on 25 January in Nature on the disruption to the ecosystem.

Assistant Professor Vedran Dunjko and his team received a gift from Google to support their quantum research. The research focuses on whether quantum computers can provide new ways of understanding the mysteries of high-energy physics.

This project studies the roles of prehistoric foragers in past ecosystems to establish the character of past “natural” landscapes and enhance the management of current ones.
