Professor Lee’s research has focused on geotechnical engineering, rock mechanics, environmental geotechnology, and geological disaster prevention, with particular emphasis on the safety assessment and seismic design of large dams and nuclear power facilities. His engineering work in Canada, China, and other countries has included safety assessments of 68 hydropower dams, the development of seismic risk assessment methodologies for the Hong Kong region, and contributions to the geotechnical feasibility studies and design verification of major projects including the Three Gorges Dam, Ertan Hydropower Station, and Lijiaxia Hydropower Station. He has authored more than 300 engineering and scientific publications and 16 monographs, and has served as a scientific and technical consultant to the United Nations Development Programme, the World Bank, the Asian Development Bank, and the International Atomic Energy Agency. His honours include the K. Y. Lo Medal of the Engineering Institute of Canada (2001), the Fulbright Distinguished Scholar Award (2005), the Gold Medal of the Hong Kong Institution of Engineers (2009), the Silver Bauhinia Star (2005) and Gold Bauhinia Star (2013) of the Hong Kong Special Administrative Region, as well as honorary doctorates from the University of Western Ontario, the University of Plymouth, Edinburgh Napier University, the University of Macau, and the Open University of Hong Kong. Through his engineering practice, international consultancy, and academic leadership, Professor Lee has contributed to connecting advances in geotechnical science and engineering with the safety and resilience of energy infrastructure, geological hazard mitigation, and sustainable development.
