Post Doc Research Fellow Lab The High Energy Physics Division at Argonne National Laboratory (ANL) invites applications for a Postdoctoral Research Associate position to join our team working on the ATLAS experiment at the Large Hadron Collider (LHC). The successful candidate will contribute to a broad research program that includes physics analysis, detector performance studies, experiment operations, and upgrade activities. This is an exciting opportunity to work within a collaborative group with deep expertise in silicon detectors, Trigger/DAQ (TDAQ) systems, software, and computing. The Argonne ATLAS group plays a leading role in detector operations and in major upgrade efforts, including the ITk Pixel detector and TDAQ systems. The group is also actively advancing work in high-performance computing (HPC) and machine learning (ML) to address future physics and detector challenges. Current physics interests include Standard Model measurements and searches for new phenomena. We welcome applicants who are excited to contribute to both the scientific and technical aspects of the ATLAS program in a highly collaborative research environment. Recent or soon-to-be-completed PhD (within the last 0-5 years) in field of experimental particle physics or a closely related field Experience in experimental high-energy physics Demonstrated ability to contribute to physics analysis, detector performance studies, detector operations, and/or upgrade activities Strong skills in scientific programming, software development, and data analysis Ability to work effectively in a collaborative, multidisciplinary research environment Experience with the ATLAS experiment or another collider-based high-energy physics experiment Experience with silicon detectors, Trigger/DAQ systems, or detector operations Experience in software and computing, including distributed computing, high-performance computing (HPC), or machine learning (ML) Application Review Review of applications will begin once the application is complete and will continue until the position is filled.
