Can we reconstruct ancient pathogen genomes from animal remains? Can paleopathology help prioritize promising specimens? Our new paper demonstrates this by screening more than 300 specimens from across Eurasia over the past 6,000 years. www.nature.com/articles/s41...

I’m happy to share the latest paper by our group in Mainz titled: “Demography and life histories across the Roman frontier in Germany 400–700 CE” that was just published in Nature. I’m proud to have been part of this amazing group effort! www.nature.com/articles/s41...

I have an open postdoc position in my group. If you're excited about developing machine learning methods for multi-omics data analysis in metabolic diseases, I’d love to hear from you. Please apply here euraxess.ec.europa.eu/jobs/430305

"The Cemetery at the Edge of the Islamic World" www.youtube.com/watch?v=OX1u... Evolutionary Insights by Anthropology net Podcast

New paper alert 🚨 Researchers at #CPGStlhm have analyzed ancient genomes from an Islamic cemetery in Ibiza (950–1150 CE) 🏖️ They found a highly diverse community with ancestry from Europe and North Africa! The paper was published in @natcomms.nature.com OA link www.nature.com/articles/s41...

By investigating the presence of pathogens in the remains, the authors detected one individual carrying Mycobacterium leprae 🦠 (the bacteria responsible for leprosy), providing insight into the health of medieval Ibiza societies.
