Dr. Hengxing Lan is a professor at the Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences (CAS), China. He is the President of the Landslide Nomenclature Commission (C37), International Association for Engineering Geology and the Environment (IAEG). He serves on the editorial board of high-profile journals in geology and geotechnical engineering. His research is primarily focused on the characterization and modeling of rock and soil strength and failure, with a particular emphasis on the microscopic anisotropic control theory of rock mass deformation and failure. He has published over 200 academic papers and 15 scientific consulting reports that have been adopted by the Chinese government. The geological hazard dynamics model he proposed has been successfully applied in academic and engineering communities of nearly 40 countries worldwide, and has been cited in research reports by the US Academy of Sciences.
