Applications are invited for a Postdoctoral Research Associate (PDRA) position within the Department of Earth, Ocean and Ecological Sciences at the University of Liverpool (UoL), UK. The position is funded by the Natural Environment Research Council (NERC) Pushing the Frontiers award CALDERA 'Collaborative Approach to integrate multidisciplinary datasets into volcanic eruption assessments' led by Professor. Janine Kavanagh, Dr. Katy Chamberlain and Professor. John Wheeler. Funding is available for up to 24 months. The position is open from 1 May 2026 and is anticipated to commence no later than 1 October 2026. You will work on one of four work packages comprising the NERC project. Work package 3 will combine field and petrological observations to understand the timescales of magma assembly and ascent at the Diamante-Maipo volcanic system located in the Andes and on the border of Chile and Argentina. You will be supervised by Dr Katy Chamberlain (Lecturer in volcanology) and collaborate with our academic and volcano monitoring agency Project Partners in Chile and Argentina, along with the entire project team. You will plan and conduct two field campaigns to Diamante-Maipo to map, log and sample its volcanic sequences and reconstruct a model of its volcanic plumbing system architecture. You will collect mineral texture and composition data using a range of geochemical methods including SEM, EPMA and LA-ICPMS. To identify the timescales of magmatic processes at Diamante-Maipo and assess how the spectrum of magmatic timescales has changed across the lifetime of the caldera, you will undertake diffusion modelling on mineral phases and macrocryst-hosted melt inclusions. Longer timescales of magmatic processes will be obtained from zircon crystallisation ages. You will work alongside other Postdoctoral Researchers and academics in Liverpool and overseas and will be expected to provide guidance to PhD and masters students. You will further be expected to publish first-authored research papers in high-ranking journals and present at international conferences. To help meet the project's impact goals, they will assist in the creation, delivery and distribution of educational materials for school children via outreach activities, and they will co-organise an international workshop for delegates from both government organisations and academia. If you are still awaiting your PhD to be awarded you will be appointed at Grade 6, spine point 30. Upon written confirmation that you have been awarded your PhD, your salary will be increased to Grade 7, spine point 31.
