Life

Chang moved with her family to Taiwan shortly after the Communists came to power in China (1949) , studied at the National Taiwan University (bachelor's degree in 1970) and received his doctorate in 1974 from the University of California, Berkeley under Donald Sarason ( On the structure of some Douglas Subalgebras ). Then she was 1974/75 Assistant Professor at the State University of New York at Buffalo , then until 1977 Assistant Professor at UCLA and 1977 to 1980 at the University of Maryland in College Park. From 1980 she was an Associate Professor and from 1982 Professor at UCLA. There she stayed, only interrupted from a year 1989 as a professor at the University of California, Berkeley until 2000. In addition, she was professor at Princeton University from 1998 , where she was director of the graduate center of the mathematics faculty from 2002 to 2006. Among other things, she was a visiting scholar at the Institute for Advanced Study (1976/77) and the ETH Zurich .

Among other things, Chang dealt with the boundary behavior of limited analytical functions on the unit disk, real harmonic analysis and applications of partial differential equations in geometric problems, such as the study of the spectrum of the Laplace operator on manifolds, the study of the partial differential equations for the Gaussian curvature on the sphere and the conformal geometry of four-dimensional manifolds.

Chang was a Sloan Fellow in 1979/80 and a Guggenheim Fellow in 1999. In 1986 she was invited speaker at the ICM in Berkeley (Extremal functions in a sharp form of Sobolev inequality) and in 2002 she gave a plenary lecture at the ICM in Beijing with her husband Paul C. Yang (Nonlinear partial differential equations in conformal geometry). From 1989 to 1991 she was Vice President of the American Mathematical Society . In 1995 she received the Ruth Lyttle Satter Prize of the AMS and in 2001 she was a Noether Lecturer , in 2018 an ICM Emmy Noether Lecturer . In 2008 she became a member of the American Academy of Arts and Sciences and in 2009 of the National Academy of Sciences . She is a Fellow of the American Mathematical Society.

She is married to the mathematician Paul C. Yang, who is also a Princeton professor and who she worked with, and has a daughter and a son.
