Academician Shih-I Chu passed away in Taipei on August 7, 2020. He was 78 years old.

Dr. Chu was a prominent figure in the fields of quantum science and computational science. By developing numerous theories and computation methods, Dr. Chu made pioneering contributions in atomic, molecular, and optical physics; intense and ultrashort laser fields; chemical physics; many-body resonances; time-dependent density functional theory; quantum chaos and fractals; and, scattering theory and reaction dynamics. After receiving his Ph.D. in chemical physics from Harvard University in 1974, Dr. Chu taught at the Department of Physics at Yale University and the Department of Chemistry at the University of Kansas, where he became a Distinguished Professor in 1990.

In addition to his outstanding scholarly achievements, Dr. Chu dedicated himself to nurturing young scientists, founding the Kansas Institute for Theoretical and Computational Chemistry and the Kansas Center for Advanced Scientific Computing at the University of Kansas to support research in these fields. After returning to Taiwan in 2007, he continued to support scientific developments in quantum science and engineering.

During his distinguished career, Dr. Chu received numerous honors, including election as Fellow of the American Physical Society and member of the World Academy of Science. Dr. Chu was elected Academia Sinica Academician in 2006.
