Education and early career: After finishing high school in Saigon, he spent a year at the École Polytechnique Fédérale de Lausanne in Switzerland, then moved to the United States for undergraduate and graduate studies at Princeton University. He earned his PhD in 1977 under Elias Stein, with a thesis on Hölder and Lp estimates for the conjugate equation on strongly pseudoconvex domains. He was an L. E.

Columbia and leadership: Since 1978 he has been at Columbia University and served as the chair of the mathematics department from 1995 to 1998.
Honors: He received the American Mathematical Society Fellowship (1977–78) and a Sloan Fellowship (1982–84). He was an Invited Speaker at the International Congress of Mathematicians in 1994 (the second Vietnamese honored there). He won the Stefan Bergman Prize in 2009 for work on the Neumann d-bar problem and related operators. He was elected to the American Academy of Arts and Sciences in 2013, to the American Mathematical Society Fellows in 2021, to the National Academy of Sciences in 2024, and in 2025 was named the Charles Davies Professor of Mathematics at Columbia.
