Dr.-Ing. Zerong Yang is a researcher in the Department of Mechanical Engineering at Tsinghua University, China. He obtained his PhD from Friedrich-Alexander-Universität Erlangen–Nürnberg (FAU), Germany. His research interests lie in metal additive manufacturing, with a focus on powder bed fusion technologies. His work addresses numerical simulation of additive manufacturing processes, including melt pool behavior, defect formation, and microstructure evolution in advanced materials such as bulk metallic glasses, titanium aluminides, and high-temperature alloys. By combining computational modeling and experimental studies, he aims to establish reliable process–structure relationships and to enable stable, high-quality fabrication of complex components.
