Prof. Wu is engaged in research on structure-function integration of metallic thin films/coating materials. He has developed metallic thin films with high ductility, high conductivity, and long service life, thereby addressing critical bottlenecks in thin film/coating materials for major equipment and medical devices in collaboration with industrial partners. He has published over 100 SCI-indexed papers in renowned materials science journals, including Nature Electronics, Advanced Materials, Nano Letters, Acta Materialia, Materials Horizons, and Scripta Materialia, and holds more than 20 authorized invention patents. Prof. Wu serves as a council member of the Fatigue Branch of the Chinese Materials Research Society, and as a youth editorial board member for journals such as Rare Metals, Journal of Iron and Steel Research International, Acta Metallurgica Sinica, and The Chinese Journal of Nonferrous Metals (Chinese and English editions). He is the recipient of the Excellent Young Scientists Fund from the National Natural Science Foundation of China, and was named a Young Science and Technology Rising Star of Shaanxi Province.
