Professor Hsiao’s research has centred on fault tolerance, particularly the detection, diagnosis, and correction of errors in digital systems. His work has addressed error-detecting and error-correcting codes, checking and testing methodologies, fault-tolerant system design, and bar-code technology. He holds 46 international patents, with his inventions receiving ten IBM Invention Achievement Awards, two IBM Outstanding Invention Awards, and an IBM Outstanding Innovation Award. His technical publications include Principles of Electronic Computers, published in Chinese in 1964, and a 1968 English-language monograph on logic-circuit design for error detection and correction, which was subsequently translated into Russian by the Soviet Academy of Sciences. His later works include The New Era of Large Computers. He has published 58 scientific papers and contributed to the dissemination of systematic knowledge of computer engineering among Chinese-speaking readers. Through sustained industrial research, technological invention, and engagement with scientific and engineering communities in both the United States and China, Professor Hsiao has contributed to the development of dependable computing and information technology.
