Andrew Chi-Chih Yao (Chinese: 姚期智; pinyin: Yáo Qīzhì; born December 24, 1946) is a Chinese computer scientist and computational theorist. He is currently a professor and the dean of Institute for Interdisciplinary Information Sciences (IIIS) at Tsinghua University. Yao used the minimax theorem to prove what is now known as Yao's Principle.

After graduating from National Taiwan University, Yao earned his first Ph.D. from Harvard University and then a second Ph.D. from the University of Illinois Urbana-Champaign.

Yao was a naturalized U.S. citizen, and worked for many years in the U.S. In 2015, together with Yang Chen-Ning, he renounced his U.S. citizenship and became an academician of the Chinese Academy of Sciences.[1][2][3][4]
