The Advanced Photon Source (APS) (https://www.aps.anl.gov/) at Argonne National Laboratory (Lemont,  Illinois, US (near Chicago)) invites applicants for a postdoctoral position to develop physics-aware multi-modal deep learning (DL) methods. At Argonne, we are developing physics-aware DL models for scientific data analysis, autonomous experiments and instrument tuning. By incorporating prior physics knowledge into DL model design and training, these models outperform traditional methods even without labeled training data (https://www.nature.com/articles/s41524-022-00803-w). Application spaces for such models include high-resolution 3D imaging, time-resolved materials characterization, and atomic structure determination. Scientific instrument data is often multimodal in nature and developing DL models that can process and learn from multiple data streams in real-time is key to unlocking the full potential of such instruments.

The postdoctoral appointee will be responsible for developing such methods that are broadly applicable across the physical sciences but applied initially to x-ray characterization needs. They will publish results in high impact journals, present at conferences and work with the software engineering team to translate the models into production.

The successful candidate will be part of a cross-lab, highly inter-disciplinary team of experts in ML, applied math, HPC, signal processing, computational physics and x-ray science. The appointee will benefit from access to world-leading experimental and computational resources at Argonne including some of the world’s largest supercomputers (Polaris, Aurora) and one of the brightest synchrotron x-ray sources in the world (APS).

Candidates with a background in deep learning, computational physics, computational materials science, inverse problems, signal processing, x-ray science etc. are encouraged to apply.
