In 1927 he matriculated at Harvard University on a Chinese government scholarship, and studied mathematics under H. M. Morse. In 1930 he became an assistant of Solomon Lefschetz at Princeton University.
Jiang returned to China in 1931 and that year became professor of mathematics at Peking University. In 1936, he went to the United States for the second time, and studied for one year at the Institute of Advanced Studies, Princeton University. In 1937 he returned to China and taught at National Southwestern Associated University. In 1947 he pursued advanced studies in Switzerland, studying mathematics under H. Hopf. Jiang returned to China on August 8, 1949. After the establishment of the Communist State, he taught at Peking University.
