. In 1952, he graduated from Tongji University in Shanghai with a bachelor's degree in shipbuilding, and pursued graduate studies in mechanics at Tsinghua University in Beijing, starting in 1957. He taught as an assistant professor at the Dalian University of Technology before moving to Shanghai Jiao Tong University (SJTU), where he spent most of his career. He was later promoted to lecturer, associate professor, and eventually professor. He served as Communist Party Secretary of SJTU from 1986 to 1992. He published over 100 scientific papers. His research was focused on naval hydrodynamics, specifically
