Dr. Xiaozhen Jiang is Professor at Institute of Karst Geology of Chinese Academy of Geological Sciences and Deputy Director of Key Laboratory of Karst Collapse Prevention and Control of China Geological Survey. Dr. Jiang has over 30 years’ experience with prevention and control of karst collapse and other geological disasters. Dr. Jiang developed the theory that sudden karst collapse is caused by water and gas pressures in a karst system and established indicators associated with collapse occurrence and prevention. She has successfully constructed eight karst collapse monitoring and early warning demonstration stations across China. She published more than 30 peer-reviewed papers and a monograph on Karst Collapse Monitoring Technology. Dr. Mingtang Lei is Professor at Institute of Karst Geology of Chinese Academy of Geological Sciences, Director of Geological Hazard Research Department, and Director of Key Laboratory of Karst Collapse Prevention and Control of China Geological Survey. He pioneered application of large-scale analog systems to simulating karst collapse processes and led 1:50,000 karst collapse survey and risk assessment in provinces including Guangdong, Guangxi, Guizhou, Hunan, Hubei, Anhui, Jiangsu, and Chongqing. Dr. Lei has published more than 40 peer-reviewed papers, served as Editor-in-Chief of Karst Ground Collapse Prevention Engineering Survey Specification, and co-edited Karst Ground Collapse Monitoring Specification. Dr. Lei serves on editorial boards of Carsologica Sinica, Hydrogeology and Engineering Geology, and Journal of Geological Hazard and Control of China. Dr. Wanfang Zhou has more than 30 years’ experience in research and investigations related to karst geology and hydrogeology. He has completed projects encompassing karst collapse investigations, waste disposal in karst terranes, geohazards control and prevention in mines, and groundwater flow and contaminant transport modeling. He authored or co-authored eight professional books, six topical journal issues, and more than 80 peer-reviewed articles. He serves as Associate Editor of Mine Water and the Environment and on editorial boards of Environmental Earth Sciences and Carbonates and Evaporites.
