In this year in review we show you various projects we're very proud of. Driven by our values at the Faculty of Social and Behavioural Sciences.

Extensive research is being conducted at the Institute of Criminal Law and Criminology on developments in sentencing and punitive measures and how judges and other actors in the criminal justice system reach decisions. Another focus area is how punishments and measures are implemented and the effect…

The main purpose of DNAmarkerpoint is to better understand the ecology, evolution and biodiversity through the study of ancient- and modern DNA.

Knowledge and culture subproject 1:

Plants, algae and cyanobacteria have the amazing capacity to perform delicate photophysical and photochemical processes of light capture, excitation transfer, charge separation and catalysis in fluctuating living environments. As a consequence, photosynthetic proteins and membranes form dynamic architectures.…

Ships are still emitting too much nitrogen oxide. Till now it has been impossible to measure this at sea, but that is set to change. Solomiia Kurchaba combined satellite data and developed algorithms to identify which ships are emitting too much. Kurchaba received her PhD on 11 June.

Are disturbances to the brain, such as Alzheimer's or autism, linked to specific defects in the underlying communication networks in the brain? If this is the case, subtle changes in the networks can act as a marker for brain disturbances. Neuroscientist Serge Rombouts will be investigating this, together…

This pioneering project will answer this question by examining migrants through the eyes of the courts between 1600 and 1900. It aims to reveal patterns of continuity and change in: 1. Treatment of migrants by criminal courts; 2. Violence and conflicts between migrants and native born.

A dental anthropological approach to foodways, health and disease, and crafting in the pre-Columbian Caribbean.

Social evaluative fears during adolescence

On December 18th, Viktorija Kostadinova succesfully defended her doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Viktorija on this great result.

Biodiversity enables ecosystems to thrive through the synergy of functional differences among organisms. While human well-being strongly depends on biodiversity-driven ecosystem services, human actions are also at the root of current unprecedented biodiversity declines.

This thesis is a sample-based typological study of formal and semantic patterns in terms for a selection of referring (

All living creatures have to cope with environmental demands and threats that challenge their physical or emotional homeostasis.

The [A]Social Creatures Lab is an interdisciplinary research lab that focuses on understanding social interaction with and between artificial creatures. Researchers and students from the Media Technology group collaborate in it.

In this thesis, dynamic testing principles were applied to examine young children's potential for learning. Our studies focused on the role of cognitive flexibility, to further increase our understanding of the cognitive processes involved in children's ability to learn from instruction and feedback,…

This research network aims to create a shared platform for debate and dialogue on the broader theme of cultural production and exchange across different area specializations and historical periods.

Intergenerational transmission refers to the complex and dynamic process with which values, ideas and behaviors are transmitted across generations. We are specifically interested in the intergenerational transmission of behaviors and beliefs that might result in harm to the individuals involved or society…

Research on lethal violence related to criminal activities.

Promotores: Prof. Dr. Th.J.C. van Berkel, Prof. Dr. M. van Eck

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…

We showed that constitutive and inducible chemical and morphological defenses against Western flower thrips differ between tomato and chrysanthemum plants.

The Saalian archaeological record at Maastricht-Belvédère (the Netherlands).

Computational linguistics uses computational methods to help answer linguistics questions across a variety of topics.

Describing a new language for the first time is an exciting and challenging intellectual experience.

Lecture, CHiLL series

Phonology is the study of speech sounds within and across languages. It touches topics such as speech sound variation, speech sound combinations and acquisition.

If an algorithm has to learn to understand language, simply having a lot of data doesn’t help much. Like us, a computer has to learn the language in interaction with others. Tessa Verhoef is fascinated by how this interaction works.

What workflow of non-destructive techniques provides accurate, valuable data to improve our understanding of Caribbean archaeological landscapes? How were Amerindian settlements configured?

At Leiden Observatory, researchers investigate the origin of stars and their planetary systems. They detect and characterize planets around other stars (exoplanets). They study how stars and planets form. And they follow molecules from interstellar clouds to nascent planet systems. This way they address…

Metabolomicshas emerged as an important discipline to study molecular and cellular processes in living cells and organisms with the ultimate aim to obtain an answer to a given biological/clinical question.

MRFM combines the principles of magnetic resonance and atomic force microscopy.

This project aims to improve understanding of, and responses to, the phenomenon of lone actors through analysis of comprehensive data on cases from across Europe.

We explore the possibilities to combine magnetic resonance techniques with atomic force microscopy together in a single microscope: the MRI-AFM, also called Magnetic Resonance Force Microscopy (MRFM).

Detecting and combatting crime is becoming increasingly complex. Security is high on the national and international agenda. The master’s programme Crime and Criminal Justice in Leiden provides the skills to face these challenges.
