Later, Châu solved a very hard math puzzle. This puzzle is called the fundamental lemma. He worked with a man named Gérard Laumon. They used new ways to solve it. This work helped finish a big goal in math. Because of this, Châu won the Fields Medal in 2010. This is a top prize for math.

Châu has lived in many places. He studied and worked in France. Now, he works at the University of Chicago. He is also a leader for a math group in Vietnam. He even wrote a book for children. It is about a land of invisible numbers. He holds citizenship in both Vietnam and France.

Ngô Bảo Châu is a very famous mathematician. He was born in Hanoi, Vietnam, in 1972. His family loved learning and science. His father, Ngô Huy Cẩn, was a physics professor. His mother, Trần Lưu Vân Hiền, was a doctor. Châu went to special math classes in school. He was a star at the International Mathematical Olympiads. He won two gold medals there. One of those medals came with a perfect score of 42 out of 42.

Châu solved a very hard math puzzle. This puzzle is called the fundamental lemma. It was first suggested by Robert Langlands and Diana Shelstad. Châu worked with a partner named Gérard Laumon. They looked at math in a new way. They used something called geometric representation theory. They studied things called orbital integrals and perverse sheaves. This helped them solve a problem about numbers. In 2008, Châu finished the proof for Lie algebras. This completed the work for all cases.

Châu's journey took him to many countries. He wanted to study in Budapest, Hungary. However, the government there stopped scholarships for Vietnamese students. A man named Paul Germain helped him find a path to France. Châu studied at the École Normale Supérieure. He earned his PhD in 1997 from Universite Paris-Sud. He worked at many places like Sorbonne Paris North University. He is now a professor at the University of Chicago. He also helps lead a math group in Vietnam.

Many people have given Châu big awards. In 2004, he and Laumon won the Clay Research Award. The magazine Time called his work a top scientific discovery in 2009. In 2010, he won the Fields Medal. This is a very special prize for mathematicians. He also became a Knight of France's Legion of Honour in 2011. He is a fellow of the American Mathematical Society. He is also an honorary member of the London Mathematical Society.

Math is about finding patterns and solving puzzles. Châu shows us that math can be a grand adventure. He even wrote a book for children. It is called Ai and Ky in the land of the invisible numbers. This book helps young people see math differently. He holds citizenship in both Vietnam and France. He continues to teach and lead in the math world. His work connects many different parts of science together.

Ngô Bảo Châu is a world-renowned mathematician known for solving a profound problem in number theory. He was born in Hanoi, Vietnam, on June 28, 1972. He grew up in an intellectual household where science was a central focus. His father, Ngô Huy Cẩn, is a professor of physics at the Vietnam National Institute of Mechanics. His mother, Trần Lưu Vân Hiền, is a physician and associate professor at an herbal medicine hospital. This environment likely fostered his early interest in complex logical structures. Today, he holds citizenship in both Vietnam and France.

Châu’s academic journey began with a focus on advanced mathematics in his youth. He attended special mathematics classes at the Trưng Vương Middle School. Later, at age 15, he entered the High School for Gifted Students at the Hanoi University of Science. During his high school years, he became a standout competitor in the International Mathematical Olympiads. He was the first Vietnamese student to win two gold medals at these competitions. Notably, his first gold medal included a perfect score of 42 out of 42.

His path to higher education involved significant international shifts. After high school, he intended to study in Budapest, Hungary. However, the fall of Communism in Eastern Europe caused the Hungarian government to stop scholarships for Vietnamese students. A man named Paul Germain helped arrange for Châu to study in France instead. He received a scholarship from the French government to attend Paris VI University. He later entered the École Normale Supérieure and earned his PhD in 1997 from Universite Paris-Sud. His supervisor for this doctorate was Gérard Laumon.

Châu is most famous for proving the fundamental lemma for automorphic forms. This difficult mathematical concept was originally proposed by Robert Langlands and Diana Shelstad. To solve it, Châu worked with Gérard Laumon to focus on unitary groups. They developed a strategy to understand local orbital integrals through affine Springer fibers. These fibers arise within the Hitchin fibration. This approach allowed them to use geometric representation theory. Specifically, they applied the theory of perverse sheaves to a problem that was originally combinatorial and number-theoretic in nature.

In 2008, Châu successfully formulated the proof for the fundamental lemma for Lie algebras. This was a critical step in the larger puzzle. Earlier work by Jean-Loup Waldspurger had shown that the full proof depended on this specific result. By solving the Lie algebra case, Châu completed the proof for all cases. This massive achievement brought him immediate international recognition. His work bridged the gap between different mathematical disciplines, combining geometry and number theory.

His contributions have earned him the highest honors in the mathematical community. In 2004, he and Laumon received the Clay Research Award for their work on unitary groups. In 2009, Time magazine named his proof one of the Top Ten Scientific Discoveries. In 2010, he was awarded the Fields Medal, making him the first Vietnamese national to receive this honor. He was also named a Knight of France's Legion of Honour in 2011. He is a fellow of the American Mathematical Society and an honorary member of the London Mathematical Society.

Châu has held many important academic positions throughout his career. He became a professor at Paris-Sud 11 University in 2005. At age 33, he became the youngest professor in Vietnam's history. He has worked at the Institute for Advanced Study in Princeton and the Hanoi Institute of Mathematics. Currently, he is a professor at the University of Chicago, where he has served as the Chair of the Department of Mathematics since July 2023. He also serves as the Scientific Director of the Vietnam Institute for Advanced Study in Mathematics.

Beyond his research, Châu seeks to share mathematics with the next generation. He co-authored a Vietnamese children's book titled Ai and Ky in the land of the invisible numbers. This work helps make mathematical concepts accessible to younger readers. He also helped organize Asiacrypt in 2016, the first time this cryptography conference was held in Vietnam. His career demonstrates how a single mathematical proof can connect diverse fields of study. From geometry to number theory, his work continues to influence the scientific world.
