In 1988, Yau joined the mathematics faculty at
New York University. He became a full professor at its
Courant Institute of Mathematical Sciences in 1994. He then moved to
Stanford University in 2003, and then to
Harvard University in 2005. He was also a member of the
Institute for Advanced Study in Princeton, New Jersey, in 2003, and was a distinguished visiting professor there in 2013–14. According to
William C. Kirby, dean of the Faculty of Arts and Sciences at Harvard, "Professor Yau is a leader in the fields of
mathematical physics, ... who has introduced important tools and concepts to study probability, stochastic processes, nonequilibrium statistical physics, and quantum dynamics." Yau is a
2000 MacArthur Fellow. ==Honors==
