Osteoarchaeologists help forensic scientists solve crimes. They also study bone material from the Second World War in order to identify victims.

Leiden archaeologists investigate how people in the past impacted their environment. Together with scientists, environmental scientists, and humanities experts, they use this information to draw conclusions about the present – and show what we can learn from it for the future.

Archaic and Classical architectural terracottas constituted an integral part of the architecture of monumental buildings at Akragas. These objects therefore provide unique insights into the built environment of sanctuaries at this important Greek colony in Sicily. This research's multi-disciplinary…

Like any language, the natural sign languages of deaf communities differ from each other in their grammars and lexicons. A growing number of studies indicates that sign languages make use of the gestures of hearing speakers to build linguistic structure. This implies that variation and similarities…

Morphometric and morphological differences have been used extensively in the past to study domestication of the wolf and the origin of dogs. Certainly before genetic testing was performed, these methods were the only means to diverge both groups. But still now, when aDNA cannot be extracted, morphometry…

Learning from small data sets in machine learning is a crucial challenge, especially when dealing with data imbalances and anomaly detection. This thesis delves into the challenges and methodologies of learning from small datasets in machine learning, with a particular focus on addressing data imbalances…

Like any language, the natural sign languages (henceforth: SLs) of deaf communities differ from each other in their grammars and lexicons. A growing number of studies indicates that SLs make use of the gestures of hearing speakers to build linguistic structure. This implies that variation and similarities…

Social science research helps us understand human behaviour and social structures. These are determined by various factors, which makes the research complex and increases the likelihood of drawing the wrong conclusions. The choice of research method and analysis is therefore extremely important. It…

Smart algorithms and powerful processors are just as essential for astronomy as big telescopes. Astronomers at Leiden University therefore constantly operate at the interface between astronomy and data science.

Organized by the Grotius Centre for International Legal Studies, this programme enables students and professionals from all over the world to engage in discussions on the prospects and challenges of international criminal justice.

One of the current research projects funded by the profile area Political Legitimacy is the research group From Disorder to Order: Conflict and the Resources of Legitimacy.

Isotopic insights on human diet from the later stone age to Neolithic in Northwest Africa, Morocco

Biological cells, the basic building blocks of all life forms, are surrounded by a lipid membrane. More than half of the membrane is occupied by membrane proteins, which can regulate the cell functionality through specific arrangements.

The Mycenaean civilization of ancient Greek times offers enormous potential for useful information: from innovative construction methods to ways of handling crisis situations as a society. Archaeologist Ann Brysbaert and her team analyse Mycenaean construction processes in the ERC Consolidator project…

Leiden University archaeologists are reconstructing houses from the Stone Age, using only resources available during that period. This method offers surprising insights into the ingenuity of our distant ancestors, and challenges existing archaeological views.

Muslim scholars work in a long and rich tradition of knowledge-production in their own culture.

Plants could be regarded as small chemical factories, which produce chemical substances via photosynthesis. If we can imitate photosynthesis in an artificial system, we can make clean fuels and materials out of sunlight and CO2. Huub de Groot is very close to designing a system of this kind.

When a star gets too close to a supermassive black hole, it is torn apart by strong tidal forces in a tidal disruption event (TDE).

A Functional Analysis of Pre-Columbian Shell and Stone Artefacts from Anse à la Gourde and Morel, Guadeloupe, FWI

Patients share valuable advice and experiences with their peers in online patient discussion groups.

Are you currently enrolled in an applied sciences programme and are you considering a university master? At Leiden University you are more than welcome. A master at University will provide more depth in knowledge and you are able to specialise in a great number of areas of expertise. With the right…

This thesis discusses the development in Proto–Indo–European, Latin and Romance of a word–formation pattern which the most adequate terminology in use dubs ‘verbal government compounds with a governing first member’; I use the shorthand ‘pickpocket compounds’.

The second and final report on the Netherlands‘ crime-terror nexus has analysed all fourteen profiles of individuals arrested in 2015 for offences of terrorism.
