Judith Yang

Judith Yang is a Professor in the Department of Physics & Astronomy at the University of Pittsburgh, holding a secondary appointment. Her research focuses on surface reactions (oxidation, catalysis) and electron microscopy, particularly using in situ ultra-high vacuum transmission electron microscopy (UHV-TEM) to study atomic-scale oxidation dynamics. She explores how oxides form non-uniform films, challenging classical theories based on thermogravimetric analysis.

Her work combines experimental techniques like in situ TEM with computational methods (e.g., machine learning) to model oxidation mechanisms. Key areas include Cu-Ni alloy oxidation, surface segregation in dilute alloys, and catalyst design for energy applications. Collaborations span materials science, nanotechnology, and medical physics (e.g., radiation therapy imaging).

Publications highlight contributions to understanding metal oxidation kinetics, electrocatalyst characterization, and multimodal operando approaches. She actively contributes to interdisciplinary research, bridging physics, chemistry, and engineering.

Her research has implications for corrosion prevention, clean energy catalysts, and advanced materials development. She advises on grants related to in situ microscopy and collaborates with institutions globally. No specific awards are listed, but her extensive publication record reflects impactful contributions to materials science and surface physics.
