Insights in diet, climate and ecology

The dental remains of 25 enslaved Africans from the site of Newton's Plantation, on Barbados, were subjected to isotope analysis. Previous research had pointed out that the locally born individuals were subjected to high concentrations of lead poisoning. A new study, done by Dr Jason Laffoon among others…

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…

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.
