There he headed the Theoretical Physics Division of the National Research Council until 1963. In the late 1960s, he was chair of the department of Physics and Astronomy at the University at Buffalo. After 1962, he held various positions in Taiwan, including President of the Academia Sinica (1983–1994). He continued lecturing into his 90s and died on March 4, 2000.
