Baojin Zhang is a doctoral researcher in Tunnelling and Underground Engineering at Beijing Jiaotong University. His research focuses on the safe construction of tunnels under complex geological conditions, particularly the deformation mechanisms, design methods, support systems, stress-release technologies, and deformation-control techniques for deep-buried soft-rock tunnels. He has authored or co-authored 19 academic papers, including publications in Tunnelling and Underground Space Technology, Scientific Reports, Rock Mechanics and Rock Engineering, and Archives of Civil and Mechanical Engineering. He has also contributed to three academic monographs and applied for 17 national invention patents, seven of which have been granted. Baojin has participated in two projects funded by the National Natural Science Foundation of China and more than ten major industry-sponsored research projects. He has accumulated over 16 months of field research experience on major tunnel projects, including the Haba Snow Mountain Tunnel, Desheng Tunnel, and Tianshan Shengli Tunnel. His research contributions have received science and technology progress awards from a national-level industry association and China Railway Construction Corporation. He has verified peer-review experience for Scientific Reports and is willing to review manuscripts related to tunnelling and underground engineering, geotechnical engineering, rock mechanics, tunnel construction, and deformation control.
