- Senior Research Fellowship in 1998 at the The University of Hong Kong
Professor Lee is widely recognised internationally for his contributions in environmental hydraulics - in particular the theory of buoyant jets and its applications to environmental engineering. His methods for prediction of mixing of wastewater jets in moving water have been used internationally for sea outfall design and environmental impact assessment.
Professor Lee is the President of the Hong Kong Academy of Engineering Sciences and Chief Editor of the Elsevier Journal of Hydro-environment Research. He is the first Asian-based academic to receive the ASCE Hunter Rouse Hydraulic Engineering Award (2009) and the ASCE Emil Hilgard Hydraulic Prize (2013). He is past Vice-President of the International Association of Hydraulic Engineering and Research (IAHR; 2007-11), and has served as expert consultant on numerous hydro-environmental projects. He has contributed significantly to innovative flood control and water quality modelling for fisheries management in Hong Kong, and serves on advisory bodies in Hong Kong, Scotland, Germany and Singapore. He was elected to the Royal Academy of Engineering, UK, in 2008.
