Duong Hong Phong

Duong Hong Phong (, born 30 August 1953) is an American mathematician of Vietnamese origin. He is a professor of mathematics at Columbia University. He is known for his research on complex analysis, partial differential equations, string theory and complex geometry.

Education and career

After graduating from Lycée Jean-Jacques Rousseau in Saigon, Phong attended a university year at the École Polytechnique Fédérale, Lausanne, Switzerland and then went to the United States as an undergraduate and then a graduate student at Princeton University. From 1975 to 1977, he was an L. E. Dickson instructor at the University of Chicago.

In 1977, he defended his dissertation entitled "On Hölder and ''L''_''p'' Estimates for the Conjugate Partial Equation on Strongly Pseudo-Convex Domains" under the direction of Elias Stein.

For the academic year 1977–1978, Phong was a researcher at the Institute for Advanced Study in Princeton, New Jersey. Since 1978, he has been at Columbia University. He served as the chair of the Columbia math department from 1995 to 1998.

Recognition

In 1994, he was an Invited Speaker at the ICM in Zürich. He was the second Vietnamese to receive the honor (after Frédéric Pham).

In 2009 Phong was awarded the Stefan Bergman Prize for his research on the operators involved in the Neumann ''d''-bar problem and on pseudo-differential operators.

In 2013, he was elected to the American Academy of Arts and Sciences.

He was named to the 2021 class of fellows of the American Mathematical Society "for contributions to analysis, geometry, and mathematical physics".

In 2024, he was elected to the National Academy of Sciences.
