## Nonlinear Equations in Conformal Geometry## New Orleans, LA, 2001
In her thesis, Chang worked on problems in classical analysis, in particular the study of boundary behavior of bounded analytic functions on the unit disc. Since then her research interest has gradually shifted to problems in real harmonic analysis, then to spectral theory of the Laplacian, and further to problems in geometric analysis, using PDE methods to study problems in differential geometry. She is currently interested in the conformal geometry of a class of 4-manifolds. She is developing new techniques involving higher order partial differential equations to understand the conformal structures in four dimension. Chang was awarded an Alfred P. Sloan Fellowship in 1979 and a Guggenheim Foundation Fellowship in 1999. She served as Vice-President of the American Mathematical Society (AMS) from 1989 to 1991 and was awarded the AMS Ruth Lyttle Satter Prize for outstanding contributions to mathematics research by a woman in 1995. She gave an invited AMS hour addresses at the Joint Mathematics Meetings in 1991 (Louisville, Kentucky) and in 2000 (Washington, D.C.) She was an invited speaker at the International Congress of Mathematics in 1986 (Berkeley, California). Chang is a firm believer that, given a suitable environment in which to develop, women and men are equally talented in mathematics. In her undergraduate class at Taiwan, there were 12 women in a class of 40 mathematics majors. Partially due to the enriching interaction among the classmates, several went on to become successful mathematicians." Chang has one daughter and one son. Her husband, Paul Yang, is also a mathematician and a long term scientific collaborator of Chang. In her spare time, she enjoys reading novels, taking walks and listening to music. |
