On 5 September 2019, Jennifer Doekhie defended her thesis 'Dimensions of desistance: A qualitative longitudinal analysis of different dimensions of the desistance process among long-term prisoners in the Netherlands'. The doctoral research was supervised by Prof. P. Nieuwbeerta.

In 2016, Leiden University hosts the monthly meetings of the Music and Cultural Analysis reading group.

Reconstructing interactions between communities in and out of Cyprus in the early third millenium BC

From 1 August, Hermen Jan Hupkes has been appointed Professor of Non-Linear Analysis at the Mathematical Institute. 'Initially I don't think that much will change,' Hupkes says. 'My research and supervising future researchers will continue as before.'

Through the Academy of Creative and Performing Arts, multiple gifted bachelor and master students of Leiden University and the University of the Arts The Hague can fully develop both their artistic and academic talents by choosing academic or artistic minors or electives.

What types of construction materials are used in the Global South, where are they, and what levels of societal services do they support? How will material use evolve under different development pathways and paradigms? What are these materials' environmental and societal impacts now and in the future,…

Violence during war often involves upswings and downturns that have, to date, been insufficiently explained. Why does violence at a particular point in time increase in intensity and why do actors in war decrease the level of violence at other points? Duyvesteyn discusses the potential explanatory variables…

A new study published in Archaeometry describes the unexpected results obtained from analyses of five human teeth discovered in a ritual cache at an enslaved African plantation site on the island of Saba in the Caribbean.

New funding allows IBL-researcher Herman Spaink to purchase a measurement device for more studies on human diseases such as cancer and tuberculosis using zebrafish as the model system.

The production, use, and exchange of bodily ornaments through the lenses of the microscope

In this thesis we will explore the use of fuzzy systems theory for applications in bioinformatics.

Italian nurse Daniela Poggiali was arrested and convicted of murdering two hospital patients in 2014. Her case attracted the attention of Leiden statistician Richard Gill. After his investigation, together with an Italian colleague, Poggiali was acquitted last autumn. Together with fellow statisticians,…

The research programme Statistical Science is concerned with the analysis and interpretation of masses of data, the quantification of uncertainty using probability models, and the development and benchmarking of algorithms and methods with these aims.

Whether a microbe is beneficial or harmful to a plant can now be predicted with high accuracy thanks to bacLIFE. This bioinformatic tool with an intuitive interface makes it much easier to unlock the secrets of bacterial genomes. A group of Leiden biologists presented it in Nature Communications.

In several Mediterranean regions archaeological sites have been mapped by fieldwalking surveys, producing large amounts of data. These legacy site-based survey data represent an important resource to study ancient settlement organization. Methodological procedures are necessary to cope with the limits…

Speed skating coach and human movement scientist Jac Orie has been capturing all details about the performance of 'his' skaters for fifteen years. Thanks to data scientist Arno Knobbe, who calculates the collected data in new ways, Orie can train his team even smarter in the run-up to the Olympic Winter…

This dissertation focuses on developing new mathematical and statistical methods to properly represent time-varying covariates and model them within the context of time-to-event analysis.

Are predictive archaeological maps a reliable tool to play an important role in the spatial planning? One of the goals of this project was to develop best practices for the production and application of the models.

Through a range of case studies spanning the post-Cold War period in Iraq, Moldova and Serbia, this book studies asymmetric conflicts where warring sides exhibit vast power differentials.

What are the environmental impacts of widespread integration of bio-based products into the construction industry?

Archaeologist Jason Laffoon was awarded an NWO Vidi grant for an innovative investigation into ancient migrations in the western Caribbean. The innovative character of this research project lies in the wide-scale application of isotope analysis and isotope mapping. ‘We aim at further developing methods…

The LOFAR radio telescope produces petabytes of data every year. Radio Astronomers use complex multi-step pipelines to process this data and produce scientific images.

The increasing competition in the automotive industry requires the tailored, swift development of technologically sophisticated vehicles. Therefore, the computationally expensive state-of-the-art simulation technologies are combined with optimization algorithms. An example of a real-world optimization…

As of 1 June 2018 Olaf van Vliet has been appointed as Professor of Comparative Welfare State Analysis at Leiden University. The Endowed Chair in Comparative Welfare State Analysis is supported by Instituut Gak. This chair is embedded in both the Department of Economics (Leiden Law School) and the Institute…

In 2019 UNICEF published the situation analysis of children and adolescents in the Caribbean Netherlands, commissioned by the Dutch Ministry of Interior and Kingdom Relations. It is a follow-up to the first round of situation analysis on children’s rights in the Caribbean Netherlands, which was completed…

The analysis of protein residues extracted from the storage containers of circa 50,000 year old bone-tools reveals Neandertal strategic selection of bovid ribs to make some of their “lissoirs”.
