Postdoc - AI-Accelerated Diffraction Imaging of Complex Materials

Argonne National Laboratory

Lemont, IL

Job posting number: #7087558

Posted: October 21, 2021

Application Deadline: Open Until Filled

Job Description

The Computational X-ray Science (CXS) group at the Advanced Photon Source (APS) (https://www.aps.anl.gov/) is involved in developing computational solutions for materials characterization using x-rays. CXS supports a wide variety of advanced scientific instruments at the APS by developing new algorithms, AI/ML models and building software frameworks for x-ray techniques of diffraction, imaging and spectroscopy, as well as variants and combinations of these base techniques.

CXS is looking for a post-doctoral appointee to develop AI/ML techniques for automated data analysis of high energy x-ray tomographic data using both diffraction and absorption-based contrast. The successful candidate will work to accelerate processing and feature detection of this multi-modal 3D data, including use of automated morphology quantification. These computational developments are aimed at enabling studies of larger numbers of samples as well as more complex samples - which may contain multiple phases and several tomographic features – than possible today.

Candidates with a background in machine learning, computational materials science, computational physics, image processing, inverse problems, applied math and x-ray science are encouraged to apply.
