Despite my insomnia, I'm very happy to share our preprint: a multi-disciplinary assessment of a sheep mass mortality event from ~18th century France. We report the first ancient sheeppox virus (think smallpox) and the Taenia hydatigena (nasty roundworm) genomes.

Evidence of sheeppox in 17th-19th century France: a multi-disciplinary investigation of a sheep mass mortality assemblage
Epizootic outbreaks posed major threats to food security, economic stability, and animal welfare in past communities. While these events and their impacts are well documented in historical records, ve...

I will be recruiting two PhDs for my ERC Project HERDPATH - let's discover out how livestock and pathogens evolved together using #aDNA. Projects will be animal or pathogen focused but will be in dialogue.
Details at my quaint website below. Deadline 3rd October.

Shameless promotion from #isba11 - I'll be hiring PhDs to start early 2026 (plus postdocs starting later), using #adna to study livestock and pathogen coevolution, particularly looking at inbreeding and immune gene evolution!
