Sir William Dunn School of Pathology, South Parks Road, Oxford We are looking to recruit two enthusiastic and motivated Postdoctoral Research Assistants to join the group of Professor Ervin Fodor in the Sir William Dunn School of Pathology at the University of Oxford. The aim of the project is to gain in-depth molecular insights into how influenza viruses replicate, helping us better understand the molecular factors that determine host range and virulence — and ultimately contributing to the development of new antiviral approaches. The project takes a cross-disciplinary approach, combining biochemical, biophysical, cell biological, and virological methods, including reverse genetics for generating recombinant influenza viruses, proximity labelling, and cross-linking mass spectrometry. The positions would suit enthusiastic and highly organised postdoctoral scientists with an interest in viral RNA-dependent RNA polymerases and its role in transcribing and replicating the viral RNA genome, as well as on the molecular mechanisms involved in the nuclear import, export, cytoplasmic trafficking, and assembly of the viral genome. There will also be an opportunity for the postholders to pursue their own ideas within the broader theme of understanding viral molecular mechanisms, including projects that could support future fellowship or independent position applications. Applicants should hold, or be close to completion of, a PhD/DPhil in biochemistry, molecular biology, structural biology, virology, or a related field. Experience with molecular cloning and cell culture is essential. Experience with any of the other methods mentioned would be an advantage, but is not essential, as training will be provided. The positions are funded by the UKRI-MRC and are for a fixed term until 30 September 2028. Informal inquiries about the positions can be sent to Professor Ervin Fodor: .
