Postdoctoral Appointee AI for Coherent X ray Imaging

Job description

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 build a physics-informed AI framework that decodes the complex relationships between material defects, functional fields (e.g., strain, electrostatic potential), and device performance, with a primary focus on leveraging advanced synchrotron X-ray techniques.

The successful candidate will be at the forefront of integrating cutting-edge AI methodologies with world-leading X-ray characterization.

You will develop and apply novel machine learning models—including Physics-Informed Neural Networks (PINNs), variational autoencoders, and geometric deep learning—to fuse multimodal data from diverse experimental probes like Bragg Coherent Diffraction Imaging (BCDI), ptychography, and X-ray Photon Correlation Spectroscopy (XPCS).

The goal is to move beyond simple correlations to discover the causal, governing rules of defect-property relationships in next-generation electronic materials.

This role involves creating AI models for real-time data analysis, enabling autonomous experiments through active learning and curiosity-driven exploration, and contributing to a robust data infrastructure that makes large-scale, multimodal datasets FAIR and AI-ready.

You will publish findings in high-impact journals, present at major international conferences, and work within a large, interdisciplinary team of experts from multiple national laboratories and universities.

The appointee will benefit from direct access to the unique capabilities of the upgraded APS, leadership-class computing at the Argonne Leadership Computing Facility (ALCF), and state-of-the-art microscopy at the Center for Nanoscale Materials (CNM).

Candidates with a strong background in computational science, machine learning, and experience with synchrotron data analysis are strongly encouraged to apply.

**Position Requirements**

+ PhD completed in the past 5 years or soon to be completed in a relevant field of study.
+ Experience with deep learning (DL) frameworks such as PyTorch, TensorFlow, or JAX.
+ Strong programming proficiency in Python.
+ Demonstrated experience with coherent X-ray techniques (e.g., BCDI, ptychography, XPCS) and associated data analysis.
+ Ability to model Argonne’s core values of impact, safety, respect, integrity, and teamwork.
+ Interpersonal skills, oral and written communication skills, and ability to interact with people at all levels both within and outside the laboratory.

**Preferred Knowledge, Skills, and Experience** **:**

+ Experience with scientific AI techniques like Physics-Informed Neural Networks (PINNs) and geometric deep learning.
+ Experience with active learning, agentic workflows, or other methods for autonomous experimentation.
+ Familiarity with high-performance computing (HPC) environments and large-scale data management.
+ Experience with version control (e.g., Git) and collaborative software development practices.
+ Experience with real-time analysis and instrument control at a user facility.
+ Skill in both written and oral scientific communication.
+ A strong track record of working collaboratively in a diverse, team-oriented research environment.
