Cap-Exempt H-1B Position — No lottery required
We are seeking a Postdoctoral Research Associate to join the Structural Science Group within the X-ray Science Division (XSD) at the Advanced Photon Source (APS), Argonne National Laboratory. This position is part of the DOE-BES initiative Integrated Scientific Agentic AI for Catalysis (ISAAC), a multi-facility collaboration integrating experimental measurements, simulations, and data science to enable physics-informed AI agents that accelerate discovery in catalysis science. The successful candidate will focus on the development and application of machine learning and AI approaches to analyze synchrotron X-ray scattering data, including X-ray diffraction and total scattering measurements. The research will emphasize extracting physically meaningful descriptors from complex scattering datasets and integrating these results into the ISAAC multimodal data ecosystem to support autonomous scientific discovery. The postdoctoral researcher will contribute to the development of AI-ready data pipelines and analysis frameworks that enable rapid interpretation of scattering measurements and facilitate the training of intelligent agents capable of guiding experiments and simulations in catalytic materials research. Responsibilities: - Develop and apply machine learning and data-driven methods for the analysis and interpretation of synchrotron X-ray scattering data, including diffraction and total scattering measurements. - Design computational workflows that transform experimental data into AI-ready descriptors suitable for integration within the ISAAC data infrastructure. - Collaborate with beamline scientists and user groups to incorporate scattering datasets into multimodal AI frameworks combining experimental measurements and simulations. - Contribute to the development of automated data processing and analysis pipelines for large-scale scattering datasets. - Participate in synchrotron experiments at APS beamlines to generate datasets that support algorithm development and
