Guang Yang

Dr. Guang Yang is an electrochemical materials scientist at Oak Ridge National Laboratory with a joint faculty appointment at the University of Tennessee, Knoxville. His research advances the science of processing and manufacturing for next-generation electrochemical energy technologies, with a central focus on how synthesis, materials processing, interface formation, and device fabrication govern microstructure, transport, reaction pathways, and long-term performance.

Working at the intersection of materials chemistry, electrochemical engineering, and advanced characterization, Dr. Yang combines an engineering mindset with deep fundamental inquiry. His research is driven by process–structure–property–performance relationships: understanding how materials and interfaces evolve during processing and operation, and using that knowledge to design scalable, reliable, and manufacturable electrochemical systems. He develops operando spectroscopy, imaging, and electrochemical diagnostic platforms to probe complex reaction mechanisms, interfacial evolution, and degradation processes under realistic operating conditions.

Dr. Yang has also pioneered AI- and machine-learning-enabled workflows for high-throughput processing and interpretation of multimodal spectroscopy and imaging datasets, including feature extraction, signal deconvolution, pattern recognition, and quantitative structure–property correlation. His research spans high-energy all-solid-state batteries, redox flow batteries for grid-scale energy storage, Li/Na–S batteries, electrochemical CO₂ conversion, and electrified surfaces and interfaces.

He has authored more than 100 peer-reviewed publications, with an H-index of 39 and an i10-index of 80, and has contributed two book chapters. Since launching his independent research career, Dr. Yang has led more than $10 million in research programs supported by the U.S. Department of Energy and industrial sponsors. His honors include the ARPA-E Early Career Award, the RSC Emerging Investigator Award, and the UT-Battelle Outstanding Scholarly Output Award.
