Ngô Bảo Châu (born June 28, 1972) is a Vietnamese mathematician at the University of Chicago, best known for proving the fundamental lemma for automorphic forms proposed by Robert Langlands and Diana Shelstad.


Chau was born in 1972, the only son to an intellectual family in Hanoi, North Vietnam. His father, professor Ngo Huy Can, is a full professor in Physics at the Vietnam National Institute of Mechanics. His mother, Tran Luu Van Hien, is a doctor who is an associate professor at a herbal medicine hospital in Hanoi.

At the age of 15, he was admitted into a mathematics-specializing class of the Vietnam National University High School (Khối chuyên Tổng Hợp – Đại học Khoa Học Tự Nhiên Hà Nội), formerly known as A0-class. In grade 11 and 12, Chau participated respectively in the 29th and 30th International Mathematical Olympiad (IMO) and became the first Vietnamese student to win two IMO gold medals, of which the first one was won with a perfect score (42/42).

After high school, Chau prepared to study in Budapest but in the aftermath of the fall of Communism in Eastern Europe, the new Hungarian government stopped providing scholarships to students from Vietnam. After visiting Ngo's father, Paul Germain, secretary of the French Academy of Sciences, arranged for Ngo to study in France. He was offered a scholarship by the French government for undergraduate study at the Paris VI University but he chose to study in the prestigious École Normale Supérieure. He obtained a PhD in 1997 from the Universite Paris-Sud under the supervision of Gérard Laumon. He became member of CNRS at the Paris 13 University, where he stayed from 1998 to 2005. There, he defended his habilitation degree in 2003.

He became Professor at Paris-Sud 11 University in 2005. In 2005 Chau received the title of professor in Vietnam and thus became the youngest professor ever in Vietnam at the age of 33. Chau then worked, since 2007, also at the Institute for Advanced Study, Princeton, New Jersey while holding a position at the Hanoi Institute of Mathematics. He joined the mathematics faculty at the University of Chicago on September 1, 2010. He holds both Vietnamese and French citizenship.


Chau first came to prominence by proving, in joint work with Gérard Laumon, the fundamental lemma for unitary groups. Their general strategy was to understand the local orbital integrals appearing in the fundamental lemma in terms of affine Springer fibers arising in the Hitchin fibration. This allowed them to employ the tools of geometric representation theory, namely the theory of perverse sheaves, to study what was initially a combinatorial problem of a number-theoretic nature. Chau eventually succeeded in formulating the proof for the fundamental lemma for Lie algebras in 2008. Together with results from Jean-Loup Waldspurger, who had earlier deduced stronger forms of the fundamental lemma from this result, this completed the proof of the fundamental lemma in all cases.


In 2004, Chau and Laumon were awarded the Clay Research Award for their achievement in solving the fundamental lemma proposed by Robert Langlands for the case of unitary groups.[4] Chau also became the youngest professor in Vietnam in 2005. His proof of the general case was selected by Time as one of the Top Ten Scientific Discoveries of 2009. In 2010, he received the Fields Medal.
