When he was fourteen, he moved to Hong Kong with his family where, after graduating from Pui Ching Middle School, he studied mathematics at The Chinese University of Hong Kong from 1966 to 1969. He undertook graduate studies at the University of California, Berkeley, where his advisor was Shiing-Shen Chern. He received his Ph.D. from the University of California, Berkeley in 1971. Afterwards, he spent a post-doctoral year at the Institute for Advanced Study and then another two years as an assistant professor at the State University of New York at Stony Brook. Prof. Yau is currently the William Caspar Graustein Professor of Mathematics and the Chairman of the Mathematics Department at Harvard University. Prof. Yau is one of the most respected mathematicians in the world. He received 10 honorary degrees from top universities around the world, including Harvard, National Taiwan University, Zhejiang University, and The Chinese University of Hong Kong, for his seminal contributions in differential geometry, differential equations and general relativity. Moreover, Prof. Yau is the Editor-in-Chief of the Journal of Differential Geometry (1980–present), Advances in Theoretical Mathematics and Physics (1997–present), Dynamics of Partial Differential Equations (2004–present), Communications in Number Theory and Physics (2007–present), and the Asian Journal of Mathematics (1997–present).
