Postdoctoral Appointee – Machine Learning for X-ray Science

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 and approaches, for x-ray science and instruments. These methods will accelerate the scientific discovery process by quickly extracting useful information from vast quantiles of data, and by providing feedback to the experiment system enabling autonomous control and steering. New fast data reduction approaches and systems will be developed and implemented that operate close to instruments at the edge, and that leverage high-performance computing environments when needed. This position will be funded under a Department of Energy award, “Intelligent Learning for Light Source and Neutron Source User Measurements Including Navigation and Experiment Steering (ILLUMINE).” The selected candidate will work as a part of a multidisciplinary research team comprised of scientists from Scientific User Facilities at several National Laboratories.

The X-ray Science Division (XSD) of Argonne National Laboratory enables world-class research using x-rays by developing cutting edge X-ray instrumentation and techniques, and pursuing research in the physical, chemical, environmental, and materials sciences. To accomplish this mission, XSD fully operates 43 beamlines and is a partner in the operation of three more beamlines at the Advanced Photon Source (APS).

Today, the APS collects approximately 10 PB of raw experimental data per year from approximately 100 sophisticated instruments performing work in a variety of scientific domains. Over the coming decade, the APS anticipates this annual data volume will increase by multiple orders-of-magnitude. This is an exciting opportunity to be at the forefront of using advanced computational methods and systems, including machine learning, to develop data and computing solutions needed to answer pressing scientific questions that face the nation today.

The successful candidate will perform R&D and other activities to collaboratively develop and apply new approaches for intelligent learning and autonomous control for light source data and experiments. The successful candidate will implement and deploy these approaches for use on facility beamlines, evaluate the results, and disseminate findings through scholarly journals and conferences.
