Project Overview: This PhD project, based at the University of Southampton's School of Ocean and Earth Sciences, investigates the processes and timescales by which supervolcanoes become primed for eruption. Focusing on the giant magma body beneath the Central Andes, the research combines fieldwork, crystal geochemistry, and computational modelling to decode the triggers of supereruptions. The project aims to answer fundamental questions about how and how quickly supervolcanoes can transition from a dormant to an eruptive state. Research Areas: The project sits at the intersection of applied geology, geochemistry, geophysics, geoscience, and volcanology. Students will gain hands-on experience in field-based data collection, laboratory analysis of crystals, and advanced computational modelling techniques. The interdisciplinary nature of the project provides a comprehensive training environment for those interested in earth sciences and volcanic processes. Supervision: The supervisory team includes Dr G Weber, Prof A Milton, Dr D Keir, and Prof JB Blundy, who collectively bring expertise in volcanology, geochemistry, and geophysics. The team offers a supportive and stimulating research environment, with opportunities for collaboration and skill development. Eligibility: Applicants should possess or expect to achieve at least a 2:1 undergraduate degree (or equivalent) in geology, geoscience, earth science, or a closely related discipline. Experience in fieldwork, geochemistry, or computational modelling is advantageous. Non-native English speakers may need to demonstrate English language proficiency as per University of Southampton requirements. Funding: Funding details are not specified in the current announcement. Prospective applicants are encouraged to check the project link or contact the supervisors for the latest information on available funding or studentships. Application Process: Applications should be submitted online via the University of Southampton portal by 8 January 2026. Required documents typically include a CV, academic transcripts, and a personal statement. Early contact with the supervisory team is recommended for further guidance.
