Proceedings of the 18th Conference of the Associated Research Centers for the Urban Underground Space

Dr. Wei Wu is an Associate Professor at Nanyang Technological University (NTU), Singapore. He received his PhD degree at Swiss Federal Institute of Technology in Lausanne (EPFL), Switzerland. Prior to joining NTU, he was a Postdoctoral Scholar at Stanford University, USA. He serves as the Honorary Secretary of Society for Rock Mechanics & Engineering Geology (Singapore), the Associate Editor for International Journal of Rock Mechanics and Mining Sciences, and the Assistant Chair for Research in School of Civil and Environmental Engineering at NTU. His research focuses on experimental geophysics and energy geomechanics, with emphasis on underground space development, geo-energy extraction and storage, as well as induced geohazards due to climate change and energy extraction. Professor Chun Fai Leung is an emeritus professor in the Department of Civil and Environmental Engineering at the National University of Singapore. He graduated from the University of Liverpool with B.E. in 1977 and Ph.D. in 1981. He is a fellow of Academy of Engineering Singapore. He is a registered professional engineer (geotechnical specialist) in Singapore and a chartered civil engineer in the UK. Prof Leung is currently the Executive Editor-in-Chief of the International Journal on Deep Underground Science and Engineering. He has served as a geotechnical consultant for many government and private organizations involving projects in Singapore and overseas. Dr. Yingxin Zhou is the Technical Director with Knights Synergy (S) Pte Ltd. He has more than 30 years of experience in research, engineering, and teaching in rock mechanics, rock engineering and underground space technology, and played leading roles in several major pioneering rock engineering and research projects in Singapore. Dr Zhou has served in various leadership positions in local and international societies related to rock engineering and underground space. He is a member of the Editorial Board of the International Journal of Tunnelling & Underground Space Technology, Fellow of the Academy of Engineering Singapore, and Fellow of the International Society for Rock Mechanics & Engineering. He received the 2018 Defence Technology Prize Individual (Engineering) Award in Singapore. Professor Xiaozhao Li is the founding Director of the Yunlong Lake Jiangsu Provincial Laboratory for Deep Underground Science and Engineering; the Director of the State Key Laboratory for Geo-Mechanics and Deep Underground Engineering, China University of Mining & Technology; the Director of the State Overseas Expertise Introduction Centre for Discipline Innovation of Deep Underground Exploration & Development; the Chair of ACUUS-GEO, International Working Group on Urban Geology and Underground Space of ACUUS; the Chairman of the Deep Underground Space Exploration and Development Branch of CSRME (China Society for Rock Mechanics and Engineering). Professor Li is the founding president and vice editor-in-chief of the International Journal on Deep Underground Science and Engineering.
