Mr. Wei Liu is a dedicated researcher whose work focuses on the hydro-mechanical behavior of loess, unsaturated soil mechanics, and geotechnical hazard mitigation, supported by 239 citations, 29 publications, and an h-index of 8 in his Scopus research profile. His studies encompass the effects of pre-dynamic loading, strong seismic events, and long-term earthquake influences on loess structure, addressing how these factors alter hydraulic properties, liquefaction potential, suction stress, and microstructural evolution. Through systematic laboratory investigations, he has analyzed variations in hydraulic behavior with soil depth, the influence of lignin content and mixing methods on unsaturated loess, and the mechanisms of rainfall- and irrigation-driven landslides, providing valuable frameworks for predicting slope failure in regions where loess is predominant. His work also integrates microstructural characterization to explain mechanical responses under dynamic and static loading, offering practical insights for disaster prevention in earthquake-prone environments. Additionally, Dr. Liu has contributed to advancing knowledge on expansive clay behavior through experimental studies on chemical factors affecting swelling and shear strength, illustrating his versatility across geotechnical material systems. His research on root–soil composite reinforcement for slope stabilization in mining areas demonstrates a commitment to environmentally aligned engineering solutions. Across his publications, Dr. Liu combines experimental precision with applied relevance, producing impactful findings that enhance understanding of soil response mechanisms and inform safer geotechnical design practices. His sustained contributions reflect strong scholarly merit and make him a compelling candidate for recognition through the Best Researcher Award.
