Job Description

The X-ray Science (XSD) division at Argonne National Laboratory invites applications for postdoctoral researchers position for a project to develop artificial intelligence (AI) and machine learning (ML) methods to enhance high-energy X-ray diffraction microscopy at the Advanced Photon Source. The extreme volume and velocity of information associated with this non-destructive microstructure mapping technique can benefit from AI/ML at each stage of data flow, from the sensor to the data center. Because such tools can run at high speeds, thanks to advances in AI streaming inference accelerators, it becomes feasible to extract salient information from in-flight data, in real time, and thus both enabling fast feedback and reducing downstream computational burden. The successful candidate will conduct cutting-edge research in data science and deep learning and apply it to scientific problems, particularly in the materials science and engineering fields. The candidate will play a key role in developing physics-aware AI/ML models, developing workflow building blocks and implement high-speed training on data center AI systems (e.g., Cerebras CS-1 ML accelerator and Argonne's Aurora exascale supercomputer), end-to-end model training workflows and explore AI accelerators for simulation applications.
