Post-Doctoral Research Fellow in Ancient Environmental DNA:Whiteknights Reading UK We are seeking a highly motivated Post-Doctoral Research Fellow to join our research team at Reading, focusing on sedimentary DNA (sedaDNA / environmental DNA) from soils and sediments from the project’s case study regions in Spain and North Africa. You will contribute to the reconstruction of past landscapes and human-environment interactions through the analysis of sedimentary DNA. This includes analysing samples from terraces, irrigated fields and archaeological sites, and using eDNA metagenomics and metabarcoding approaches for multi-species detection, with the aim of characterising changing plant and animal species diversity and richness over time. The position will involve fieldwork, laboratory work, data analysis, and collaboration with an interdisciplinary team of archaeologists, palaeoecologists and historians.

Really enjoyed hosting @palaeopete.bsky.social yesterday for an excellent departmental seminar on applications of sedimentary ancient DNA, and a subsequent PhD viva.

I learnt many things!

@alexgilardet.bsky.social et al. recovered ancient DNA from bovine bones in the Denisova cave to characterize Pleistocene bovine diversity, identifying the Altai Mountains as a hotspot for bovine diversity.

Uh oh. What's this? Two unabashed extroverts given guitars and a remit to roast the field of ancient DNA? Sounds like trouble. One can only hope that if there is video footage, the people responsible have the good sense not to upload it for public viewing. No one wants to see this!
