Dr. Caoyuan Niu | Geotechnical Engineering | Best Researcher Award

Senior Engineer‌ | China Railway No.4 Engineering Group Co., Ltd | China

Dr. Caoyuan Niu is a dynamic researcher specializing in bridge and tunnel engineering, with a strong focus on the mechanical behavior and fracture characteristics of rock and composite materials under complex environmental and loading conditions. Currently serving as a postdoctoral fellow jointly supervised by China Railway No.4 Engineering Group Co., Ltd. and Hefei University of Technology, he obtained his Ph.D. in Civil Engineering from Sichuan University in 2021. His scholarly output demonstrates a robust contribution to the field, with six SCI-indexed publications as the first author in high-impact international journals such as Rock Mechanics and Rock Engineering, International Journal of Rock Mechanics and Mining Sciences, and Cold Regions Science and Technology. In addition to his academic publications, Dr. Niu holds ten authorized invention patents, reflecting a strong orientation toward practical innovation and technology transfer. His research on the bearing capacity of rock-anchored anchorage systems and the deterioration of rock materials under freeze-thaw and hydrochemical effects has advanced the understanding of infrastructure resilience and safety in extreme conditions. Through interdisciplinary collaboration with experts in material mechanics, structural engineering, and geotechnics, he has contributed to developing safer, more sustainable design principles for large-scale bridge and tunnel projects. Dr. Niu’s scientific endeavors not only enhance theoretical insights into rock fracture mechanics but also provide applied engineering solutions that support national infrastructure development and global knowledge exchange in civil and geotechnical engineering.

Ms. Yiyi Yang | Geotechnical Engineering | Best Scholar Award

Northwestern University | China

Ms. Yiyi Yang is a dedicated researcher in geological engineering with a strong academic foundation and growing expertise in soil mechanics and geotechnical applications. Currently pursuing a master’s degree in Geological Engineering at Northwest University, Xi’an, following a successful completion of a bachelor’s degree in the same field at Xi’an University of Science and Technology, the academic journey reflects both excellence and commitment. Consistently recognized with multiple scholarships and awards, including the First-Class Scholarship at Northwest University, the performance ranking at the top of the class underscores outstanding ability and determination. Research contributions demonstrate an interest in soil-water interactions, particularly in the deformation of compacted loess under wetting and infiltration processes. Work on compaction conditions, microstructural evolution, and hydraulic conductivity showcases both analytical skills and experimental rigor. As part of a collaborative project under the supervision of Ping Li, significant insights were gained into loess behavior, which are highly relevant to civil engineering and geotechnical practices. The publication “From agricultural waste to geotechnical application: Multiscale mechanisms of apple tree biochar for loess reinforcement” in Powder Technology highlights the capacity to connect environmental sustainability with engineering innovation by exploring biochar as a reinforcement material. Beyond academics, contributions as a volunteer and recognition with a two-star volunteer award reflect a well-rounded individual balancing research, academic achievement, and community engagement. Technical skills span experimental methods, data collection, and advanced use of specialized software including AutoCAD, CorelDraw, Origin, and Python, reinforcing readiness for complex research and engineering tasks. Proficiency in English, demonstrated by CET-6, further supports the ability to engage with international research. Altogether, the profile demonstrates exceptional potential for advancing knowledge in geological engineering, particularly in sustainable geotechnical solutions that bridge environmental considerations with practical applications in soil stabilization and infrastructure development.
