The University of Southampton (Faculty of Engineering and Physical Sciences) lists a competition-funded PhD project that combines systems biology, machine learning and network science to predict how human host networks respond to bacterial and viral pathogens. The student builds a multi-omics knowledge graph of host-pathogen interactions, pathways, diseases and interventions, then develops graph foundation models and explainable-AI methods. A 2:1 honours degree is the entry requirement and the closing date is 18 December 2026. AI-for-infection-biology project; no phage focus stated, and the supervisors list did not render in the capture. Logged under topic ai-science.
