The central aim is to systematically study differences in gendered crime patterns in the records of different types of courts in various English and Dutch cities in the early modern period.

Despite their ecological, cultural, and economic importance, lion (Panthera leo) populations in Kenya are declining rapidly due to retaliatory killings following livestock depredation, depletion of wild prey, habitat loss driven by human activities, climate change, and disease.

This project investigates properties of quantity expressions across languages from the perspective of how quantity is represented in the human brain.

The following master research projects are currently open in the Bouwmeester group.

This project combines an extensive new open database on linguistic distributions, spatial modelling and areal linguistics in order to disentangle the roles of social and environmental factors on the emergence of linguistic diversity patterns of South America.

Workshop

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

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.…

Knowledge and culture subproject 1:

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.

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.

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).

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…

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?

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.

Coordination chemistry is the chemistry of metal atoms

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.

Social evaluative fears during adolescence

This thesis focuses on data found in the field of computational drug discovery. New insight can be obtained by applying machine learning in various ways and in a variety of domains. Two studies delved into the application of proteochemometrics (PCM), a machine learning technique that can be used to…

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

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

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

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…

It is widely known that conflict parties engage in ceasefires for a variety of reasons, but how do these reasons relate to the military and political aspirations of conflict party leaders?

Cities need to become greener, more biodiverse, and climate-resilient. However, many organisms that are vital for the functioning of urban green spaces and the wellbeing of urban citizens remain largely unknown.

In this book, Peter Akkermans provides a systematic overview of the Halaf culture of the 6 th millennium BC in the Syrian portion of the valley of the Balikh River, a tributary of the Euphrates.

This project aims to develop advanced data analysis methods for monitoring and increasing our understanding on biodiversity dynamics in nature reserves such as the Oostvaardersplassen.

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

The primary goal of GAP is to study the impact of globalization and internationalization policies and practices on the gender balance in research and higher education in Norway.

From the formative period of Islam to the contemporary world, Muslims have negotiated changing modalities of being Muslim.

This Thesis describes the design, synthesis and evaluation as glycoprocessing enzyme inhibitors of focused libraries of iminosugars.

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.

In this conversation-analytic study, the authors analyze conversations between researchers from different disciplines and community members to examine relationship building in real life. This is an open access article under the Creative Commons By license.
