Professor Wu’s research has centred on ocean circulation dynamics, marine environmental prediction, and data assimilation and fusion. He has led more than twenty national research projects under programmes including the National Basic Research Programme, the National High-Tech Research and Development Programme, and the National Natural Science Foundation of China, and served as Chief Scientist of a 973 Programme project on the evolution of the physical environment of China’s eastern marginal seas and its environmental effects. His theoretical work has addressed equatorial deep jets, abyssal eddies, chaotic mixing and material transport, wave-induced circulation, and decadal variability in the tropical Pacific, contributing to the development of theoretical approaches to ocean dynamics and ocean–environment interactions. He also introduced and applied the concept of a transparent ocean and contributed to the standardisation of at-sea testing for ocean observation instruments. As technical group leader of the Bohai Sea Blue Sea Action Plan, he led environmental baseline surveys and contributed to the preparation of the programme’s framework. He has published more than 170 scientific papers and three edited volumes and holds nine invention patents and software copyrights. His work has received a National Science and Technology Progress Award (Second Prize) and several provincial and ministerial awards. Through sustained research, academic leadership, and engagement with national marine programmes, Professor Wu has contributed to connecting physical oceanography with marine environmental management and to the development of ocean observation, marine science, and oceanographic education in China.
