Postdoctoral Appointee – Machine Learning for X-ray Science - Argonne National Lab : Job Details

Join to apply for the Postdoctoral Appointee – Machine Learning for X-ray Science role at Argonne National Laboratory.

The Scientific Software Engineering & Data Management Group in the X-Ray Science Division (XSD) at the Advanced Photon Source (APS) ( invites applicants for a postdoctoral position to develop and apply advanced analysis methods, including artificial intelligence and machine learning algorithms, for x-ray science and instruments. These methods will accelerate scientific discovery by extracting useful information from large datasets and enabling autonomous control and steering of experiments. The position involves developing fast data reduction approaches and systems that operate near the instruments and leverage high-performance computing environments. This role is funded under the DOE award, “Illumination Learning for Light Source and Neutron Source User Measurements Including Navigation and Experiment Steering (ILLUMINE).” The candidate will join a multidisciplinary team of scientists from various national laboratories.

The X-ray Science Division (XSD) at Argonne National Laboratory develops cutting-edge X-ray instrumentation and techniques, operating 43 beamlines at the APS, with additional involvement in three more beamlines. The APS generates approximately 10 PB of raw experimental data annually, with expectations of significant growth. This role offers the opportunity to use computational methods, including machine learning, to develop solutions for handling and analyzing large-scale data to address pressing scientific challenges.

The successful candidate will engage in R&D activities to develop and apply new approaches for intelligent learning and autonomous control of light source data and experiments. Responsibilities include implementing these approaches on beamlines, evaluating their effectiveness, and disseminating findings through publications and conferences.
