I would like to advertise two PhD positions in ancient pathogen genomics funded through my ERC project�EpidemioCene . The overall aim of the project is to better understand the epidemiological history and the determinants of infectious diseases since the end of the Last Ice Age. To this end, we will undertake large-scale paleoepidemiological and phylodynamic analyses of ancient pathogen genomic data generated from large cohorts of ancient human individuals. The project is co-hosted by the Department of Archaeogenetics at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany (MPI-EVA) and the Host-Pathogen Interaction Research Unit, Toulouse, France (UMR IHAP 1225 UT/INRAE/ENVT). In this context: - PhD 1 will develop new methods to boost pathogen detection in ancient metagenomic samples. This will include a machine-learning algorithm to optimize the identification of pathogen DNA fragments in shotgun sequencing data and a hybridization capture system to enrich samples for a wide range of pathogen species. We are looking for someone with a background in bioinformatics. Some experience with machine learning or scientific software design would be advantageous. See the complete description here . - PhD 2 will analyse ancient viral genomes using phylogenetic and phylodynamic approaches to trace geographical spread and transmission dynamics on large timescales. We are looking for someone with a background in evolutionary biology, epidemiology or related topics, and a specific interest in molecular epidemiology and viral evolution. Bioinformatics skills are required, and some experience with computational phylogenetics would be a plus. See the complete description here . Both positions are aimed at students excited to study the (pre)history and evolution of pathogens using ancient DNA data, though specific experience in this regard is not required. Candidates should have proficient English skills and a strong motivation for teamworking in an international context. PhD 1 will be based at MPI-EVA, starting ideally in August 2026. PhD 2 will be based at IHAP, with regular visits to MPI-EVA, starting ideally in October 2026. German or French skills are not required. Interested applicants should send their application via email to arthur_kocher@eva.mpg.de by May 7th. The application should consist of a single PDF document containing a cover letter (2 pages max.), a CV, a proof of your most recent degree and up to two reference letters with the names and contact information of the referees. Don't hesitate to contact me at arthur_kocher@eva.mpg.de for further questions. Best, Arthur Kocher arthur_kocher@eva.mpg.de (to subscribe/unsubscribe the EvolDir send mail to golding@mcmaster.ca)
