Bio: Jingqi Zhang is a Professor and doctoral supervisor at the School of Materials Science and Engineering, Xi'an Jiaotong University, and a member of the State Key Laboratory for Mechanical Behavior of Materials. He is a recipient of the National Young-Talent Program (Overseas Outstanding Young Scientists Fund). He received his B.S. and M.S. degrees from Northeastern University and his Ph.D. in additive manufacturing of titanium alloys from The University of Queensland, Australia, where he subsequently worked as a postdoctoral research fellow. His research focuses on laser-based additive manufacturing of metallic materials, including titanium, aluminum, copper and refractory alloys, with emphasis on microstructural uniformity control, grain refinement during solidification, solid-state phase transformations and strengthening–toughening mechanisms. He has presided over key projects of the NSFC Joint Funds and General Program. He has published over 40 first/corresponding-author papers in Science, Nature Communications, Advanced Materials, Additive Manufacturing, etc., and received honors such as the 2021 Acta Student Award and the 2024 APM Outstanding Young Scholar Award. He serves as youth editorial board member of Journal of Materials Science & Technology, Advanced Powder Materials and Materials Research Letters, and recruits graduate students in materials science, mechanics and related disciplines.
