Yu-Chi "Larry" Ho (Chinese: 何毓琦; pinyin: Hé Yùqí; born March 1, 1934) is a Chinese-American mathematician, control theorist, and a professor at the School of Engineering and Applied Sciences, Harvard University.

He is the co-author of Applied Optimal Control,[2] and an influential researcher in differential games, pattern recognition, and discrete event dynamic systems.

Yu-Chi Ho was born on March 1, 1934, in Shanghai, China, and left home at the age of 15 in 1949 to complete his high school education in Hong Kong.

His thesis A Study of the Optimal Control of Dynamic Systems was advised by Arthur E. Bryson, Jr. and Kumpati S. Narendra.

After finishing his Ph.D. in the spring of 1961, Yu-Chi Ho returned to Harvard in the fall of 1961 for a teaching appointment, receiving tenure in 1965,[4] and remained in the School of Engineering and Applied Sciences until his retirement in 2001.

He was appointed (part-time) the Chair Professor and Chief Scientist at the Center for Intelligent and Networked Systems (CFINS), Department of Automation, Tsinghua University.

[17] After joining the faculty of Harvard University, Ho developed the Ho-Kashyap rule in pattern recognition with his first Ph.D. student, Rangasami L.

His paper Nonzero Sum Differential Games[21] was an influential game-theoretic study in systems and control, following earlier work by Samuel Karlin, for example.
