Yau is a Chinese American mathematician. He currently serves as a professor of mathematics and a professor of physics at Harvard University. In 1976, Yau proved the Calabi conjecture provides solutions for multiple well-known open problems in algebraic geometry and also allowed physicists to show that string theory is a viable candidate for a unified theory of nature. Calabi–Yau manifolds are among the ‘standard toolkit’ for string theorists today. Yau received the Oswald Veblen Prize in 1981, the Fields Medal in 1982, a MacArthur Fellowship in 1984, the Crafoord Prize in 1994, the United States National Medal of Science in 1997, the China International Scientific and Technological Cooperation Award in 2003, the Wolf Prize in Mathematics in 2010, the Asian American Engineer of the Year (AAEOY) in 2010, and MG15 Award (The Fifteenth Marcel Grossmann Award) in 2018.
