How can wide-scale applications of isotope analyses and isotope mapping contribute to the identification of ancient migrants and their origins in the Western Caribbean? Can we observe linkages between individual behaviors and long-term patterns, for example as manifested in continuous waves of migration?…

The aim of the project is two-fold: first, to further scholarly understanding of the human dynamics that shaped the growth of Dorestad in a broader, international context; and second, to test the potential of multi-isotopic analyses on an early medieval Dutch assemblage.

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…

This project, under the supervision of Prof. Dr. Hans van der Plicht, comprises several studies aimed at the use of isotopes occurring naturally in organic material as tracers for both the climate change and its cultural impact at about 6200 BC. The research will be carried out by the co-applicant at…

Isotopic and zooarchaeological investigations in the Dominican Republic and Jamaica

The progressive loss and degeneration of dopaminergic neurons is a major pathological hallmark of Parkinson's disease (PD). The onset and progression of PD can be triggered by multiple risk factors, for instance, genetic mutation, environmental exposure, and aging.

Diverse types of exoplanets such as gas giants on close-in orbits (hot Jupiters) and young massive giants on wide orbits (super Jupiters), with no analogs in the Solar System, pose challenges but also opportunities to our understanding of planet formation and evolution.

Lecture

Back in 2008, Jason Laffoon moved from Chicago to Leiden. He came to join the Faculty of Archaeology’s Caribbean research group as a PhD candidate. Now he is an assistant professor, bridging departments through his innovative research methods. ‘I focus both on the archaeology of the Americas, as well…

William Pestle and Jason Laffoon recently published a new article entitled 'Quantitative paleodietary reconstruction with complex foodwebs: An isotopic case study from the Caribbean' in the Journal of Archaeological Science: Reports.

Sphingolipids are important membrane compounds with a variety of functions. In mammalian cells, different enzymes are involved in the metabolism of sphingolipids, but interruption of this metabolism process leads to different diseases.

A multiple isotope approach to human-animal dynamics in the Lesser Antilles across the historical divide

The project aims to explore Eurasian elk's role in the ecosystems of the past and its relationship with humans through analysis of its distribution and habitat in the Netherlands.

Dynamics of material, social and ideological relationships in the pre-Columbian insular Caribbean

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

The first settlers of the Caribbean have long been regarded as bands of highly mobile groups who subsisted exclusively by hunting, gathering, and fishing. In recent years, however, there has been increasing evidence for the cultivation of domesticated plants by early groups and a lower degree of mobility…

A team of three students affiliated with Leiden University is shedding new light on the lives, diets, health, and mobility of individuals buried at the historic church site in Koudekerke, Zeeland. The project, a collaboration with the Walcherse Archeologische Dienst and funded by the Municipality of…

We explored how to morphologically classify well-resolved jetted radio-loud active galactic nuclei (RLAGN) in the LOw Frequency Array (LOFAR) Two-metre Sky Survey (LoTSS) using machine learning.

In this publication, Prof. Tahir Abbas, Inés Bolaños Somoano, Joana Cook, Isabelle Frens, Graig R. Klein and Richard McNeil-Willson look into the manifesto that was linked to the Buffalo attack in order to better understand the broader context and specific factors that motivated the perpetrator.

Archaeology, World Archaeology

This handbook provides a resource for those already familiar with some kinds of micro-particles who wish to learn more about others, or for those just starting out in the study of microremains who wish to have a broad understanding about microscopic archaeology.

Planets existing in other solar systems contain invaluable information about the origin of planets and life. PhD candidate Yapeng Zhang has studied their atmospheres by looking at their smallest parts: isotopes. With her research she hopes to discover what makes our own solar system unique.

The volume is one-stop shopping for crisis studies and a number of closely related fields, providing a window onto the latest thinking in the field. The articles reflect cutting edge, state of the art scholarship and pose key questions for research and practical development.

The focus of the Multicriteria Optimization and Decision Analysis (MODA) group is to develop foundations of methods in multi-objective optimization.
