Dr. Yijin Liu is an Associate Professor in the Walker Department of Mechanical Engineering at The University of Texas at Austin. His research bridges advanced X-ray characterization, materials science, and data-driven discovery, with a particular emphasis on energy storage materials and electrochemical systems.

Building on over 15 years of experience in synchrotron science, he has pioneered the development and application of nanoscale X-ray microscopy, spectroscopy, and multimodal imaging techniques to investigate complex materials across multiple length and time scales.

His group integrates operando and in situ characterization with machine learning and scientific data mining to uncover the relationships among materials processing, microstructure, reaction dynamics, and performance.

More recently, his research has expanded into battery manufacturing science, degradation and safety, and critical-material systems, with the goal of translating fundamental scientific insights into practical materials and technological innovations.
